ULTRASOUND IN MEDICINE & BIOLOGY 2023:S0301-5629(23)00205-3. [PMID: 37414634 DOI: 10.1016/j.ultrasmedbio.2023.06.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 06/08/2023] [Accepted: 06/13/2023] [Indexed: 07/08/2023]
Abstract
OBJECTIVE Noble metal nanomaterials have been introduced as ideal sonosensitizers for sonodynamic therapy (SDT) of cancer. In this research, platinum nanoparticles (PtNPs) and mesoporous platinum (MPt) were first synthesized and then evaluated as novel sonosensitizers. METHODS Ultrasound waves were radiated at two different power densities and two different pulse ratios to develop a pulsed radiation route for SDT of the malignant melanoma cell line C540 (B16/F10). Fluorescence emission was recorded as an indicator of intracellular reactive oxygen generation during the treatment. RESULTS Platinum nanoparticles had an average diameter of 12 ± 7 nm and a zeta potential of -17.6 mV; also, MPt had a sponge-like and highly porous structure with a pore size <11 nm and a zeta potential of -39.5 mV. Both PtNPs and MPt, particularly the latter, enhanced the rate of inhibition of tumor cell growth on ultrasound radiation at an output power density of 1.0 W cm-2 and pulse ratio of 30% over 10 min without intensifying temperature. CONCLUSION Use of the developed pulsed (rather than continuous) radiation in SDT and PtNPs or MPT, without hyperthermia, resulted in a new effective cancer treatment method based on the mechanisms of cavitation and/or ROS generation.

Abstract
Nickel-zinc iron oxide (NZF) was introduced into a polyaniline (PANI) matrix by an in situ chemical oxidation polymerization approach. The surface composition and chemical states were investigated by X-ray photoelectron spectroscopy (XPS), which revealed an Fe 2p spectrum with the two peak positions of Fe 2p3/2 and Fe 2p1/2 at 711.00 and 724.48 eV, respectively. Deconvolution of the Fe 2p3/2 peak revealed two components with binding energies of 713.98 and 718.16 eV, corresponding to the presence of Fe cations in the octahedral and tetrahedral sites. Additionally, the Rietveld refinement of NZF showed a cubic system with the Fd3m space group. High-resolution transmission electron microscopy (HRTEM) analysis showed that the NZF material strongly interacts with polyaniline, while the selected area electron diffraction (SAED) pattern perfectly matched with the XRD data. Lognormal distribution was used to determine the particle size, which was found to be in the range of 1-100 nm. A flexible photodetector device utilizing the NZF-PANI nanohybrid was fabricated on an environmentally friendly, biodegradable cellulose paper substrate and the device exhibited excellent performance, i.e., a responsivity of 0.069 A W-1 and detectivity of 7.258 × 1010 Jones at a very low voltage of 0.1 V. The non-stretched device showed a responsivity of 24.980 A W-1 at 5 V, whereas at 2 cm-1 bending curvature, the device showed a responsivity of 20.175 A W-1, which was much higher than the responsivity of a commercial photodetector (<0.5 A W-1).

Abstract
Metal-based magnetic materials have been used in different fields due to their particular physical or chemical properties. The original magnetic properties can be influenced by the composition of constituent metals. As utilized in different application fields, such as imaging monitoring, thermal treatment, and combined integration in cancer therapies, fabricated metal-based magnetic materials can be doped with target metal elements in research. Furthermore, there is one possible new trend in human activities and basic cancer treatment. As has appeared in characterizations such as magnetic resonance, catalytic performance, thermal efficiency, etc., structural information about the real morphology, size distribution, and composition play important roles in its further applications. In cancer studies, metal-based magnetic materials are considered one appropriate material because of their ability to penetrate biological tissues, interact with cellular components, and induce noxious effects. The disruptions of cytoskeletons, membranes, and the generation of reactive oxygen species (ROS) further influence the efficiency of metal-based magnetic materials in related applications. While combining with cancer cells, these magnetic materials are not only applied in imaging monitoring focus areas but also could give the exact area information in the cure process while integrating ultrasound treatment. Here, we provide an overview of metal-based magnetic materials of various types and then their real applications in the magnetic resonance imaging (MRI) field and cancer cell treatments. We will demonstrate advancements in using ultrasound fields co-worked with MRI or ROS approaches. Besides iron oxides, there is a super-family of heterogeneous magnetic materials used as magnetic agents, imaging materials, catalytic candidates in cell signaling and tissue imaging, and the expression of cancer cells and their high sensitivity to chemical, thermal, and mechanical stimuli. On the other hand, the interactions between magnetic candidates and cancer tissues may be used in drug delivery systems. The materials’ surface structure characteristics are introduced as drug loading substrates as much as possible. We emphasize that further research is required to fully characterize the mechanisms of underlying ultrasounds induced together, and their appropriate relevance for materials toxicology and biomedical applications.

Abstract
Trichomoniasis, an infectious disease caused by a parasite called Trichomonas vaginalis (T. vaginalis), enhances the risk of HIV infection, cervical and prostate cancer, and infertility. Therefore, efforts have to be made for accurate, specific, and rapid diagnosise and treatment of trichomoniasis. Today, optical nanosensors have created an opportunity for diagnosis without sophisticated and expensive tools and the need for expertise; at the same time, they are highly sensitive and fast. An optical nano-genosensor was designed by conjugation of gold nanoparticles and a specific oligonucleotide (AuNPs-probe) from repeated DNA target for specific and sensitive polymerase chain reaction diagnosis of T. vaginalis gene sequence (L23861.1). The hybridization of AuNPs-probe was investigated with different concentrations of complementary sequence in synthesized target, gene sequence of standard T. vaginalis genomic DNA extraction, and PCR products of genomic DNA samples extracted from patients. Negative samples including synthesized non-complementary sequence, genomics DNA of other pathogens, and genomics DNA of healthy persons were considered for proof of the accuracy of the sensor function. The occurrence of correct hybridization was detected by adding acid to the medium and observing the changes in the color of the medium and spectroscopic spectrum. Based on spectrophotometric results, the fabricated genosensor had detection limits of 35.16 and 31 pg μL-1 for the detection of synthetic target and genomic DNA sequences, respectively. The results confirmed the correct function of genosensor for the detection of T. vaginalis in clinical samples. Advantages such as low cost, visual detection, speed, and easy diagnosis encourage the use of this sensor in pathogen detection in the future.

Abstract
BACKGROUND Nowadays, it is needed to explore new routes to treat infectious bacterial pathogens due to prevalence of antibiotic-resistant bacteria. Antimicrobial photothermal therapy (PTT), as a new strategy, eradicates pathogenic bacteria. OBJECTIVE In this study, the antimicrobial effects of a carbon nanoparticles-polypyrrole nanocomposite (C-PPy) upon laser irradiation were investigated to destroy the pathogenic gram-negative Pseudomonas aeruginosa. MATERIAL AND METHODS In this experimental study, the bacterial cells were incubated with 50, 100 and 250 µg mL-1 concentrations of C-PPy and irradiated with a 808-nm laser at two power densities of 0.5 and 1.0 W cm-2. CFU numbers were counted for the irradiated cells, and compared to an untreated sample (kept in dark). To explore the antibacterial properties and mechanism(s) of C-PPy, temperature increment, reactive oxygen species formation, and protein and DNA leakages were evaluated. Field emission scanning electron microscopy was also employed to investigate morphological changes in the bacterial cell structures. RESULTS The results showed that following C-PPy attachment to the bacteria surface, irradiation of near-infrared light resulted in a significant decrement in the bacterial cell viability due to photothermal lysis. Slightly increase in protein leakage and significantly increase intracellular reactive oxygen species (ROS) were observed in the bacteria upon treating with C-PPy. CONCLUSION Photo-ablation strategy is a new minimally invasive and inexpensive method without overdose risk manner for combat with bacteria.

Abstract
BACKGROUND Metal nanomaterials have a significant potential as photosensitizer and radiosensitizer. The purpose of this study was to evaluate the cytotoxicity of a platinum mesoporous nanostructure (Pt MN) toward a melanoma cancer cell line upon combined laser radiation (808 nm, 1 and 1.5 W cm-2) and X-ray irradiation (6 MV, 2, 4, and 6 Gy). METHODS Pt MN was synthesized by a simple procedure and characterized by field emission scanning and transmission electron microscopy. A mouse malignant melanoma cell line C540 (B16/F10) was treated with Pt MN, laser light and/or X-ray. RESULTS Pt MN had a mesoporous structure with a sponge-resemble shape comprised of ensembles of very small adhered particles of <11 nm and about 5-nm pores. While Pt MN represented a low toxicity toward and considerable uptake into the cell line in a concentration range of 10-100 μg mL-1, laser light radiation alone was also not toxic, and X-ray irradiation alone induced a limited toxicity, Pt MN was toxic against the cells in a dose dependent manner upon laser light radiation, X-ray irradiation, or their combined exposure. The killing efficacy of Pt MN upon X-ray irradiation was more obvious at 72 h post-treatment. The combined exposure (laser radiation followed by X-ray irradiation) led to a deep cell killing and a very low melanoma cell viability (∼1%). Significant melanoma cancer cell killing of Pt MN was due to reactive oxygen species (ROS) production upon combined exposure of laser and X-ray, while cell killing upon laser light radiation was due to heat generation. CONCLUSION Pt MN was introduced as a supreme laser/X-ray sensitizer for treatment of cancer with a high ability to produce ROS and a potent impact on decreasing cell viability.

Abstract
Widespread resistance to antibiotics amongst pathogens has become a tremendous challenge of high morbidity and mortality rates which increases the needs to exploring novel methods of treatment. An efficient antimicrobial procedure to root out pathogenic bacteria is photothermal therapy. In this study, antimicrobial effects of a polypyrrole-carbon nanocomposite (PPy-C) upon laser irradiation in order to destroy the pathogenic gram-positive bacterium, methicillin-resistant Staphylococcus aureus (MRSA) were assessed. The bacterial cells were incubated with 500, 750 and 1000 μg ml-1 concentrations of PPy-C and irradiated with an 808-nm laser at a power density of 1.0 W cm-2. To indicate the biocompatibility and toxic effect of the nanocomposite without and with laser irradiation, the authors counted the number of CFUs and compared it to an untreated sample. Antibacterial mechanisms of PPy-C were assessed through temperature increment, reactive oxygen species production, and protein and DNA leakages. Photothermal heating assay showed that 26°C temperature increases in the presence of 1000 µg ml-1 PPy-C led to >98% killing of MRSA. Furthermore, 20 min radiation of near-infrared light to PPy-C in different concentrations indicated destruction and reduction in the MRSA biofilm formation. Therefore, PPy-C was introduced as a photothermal absorber with a bactericidal effect in MRSA.

Abstract
Gold nanoparticles-enabled intracellular surface-enhanced Raman spectroscopy (SERS) provides a sensitive and promising technique for single cell analysis. Compared with spherical gold nanoparticles, gold nanoflowers, i.e., flower-shaped gold nanostructures, can produce a stronger SERS signal. Current exploration of gold nanoflowers for intracellular SERS has been considerably limited by the difficulties in preparation, as well as background signal and cytotoxicity arising from the surfactant capping layer. Recently, we have developed a facile and surfactant-free method for fabricating hollow-channel gold nanoflowers (HAuNFs) with great single-particle SERS activity. In this paper, we investigate the cellular uptake and cytotoxicity of our HAuNFs using a RAW 264.7 macrophage cell line, and have observed effective cellular internalization and low cytotoxicity. We have further engineered our HAuNFs into SERS-active tags, and demonstrated the functionality of the obtained tags as trimodal nanoprobes for dark-field and fluorescence microscopy imaging, together with intracellular SERS.

Abstract
Detection of leishmaniasis is important in clinical diagnoses. In the present study, identification of Leishmania parasites was performed by a label-free, PCR-free and signal-on ultrasensitive electrochemical DNA biosensor. Gold nanoleaves were firstly electrodeposited by an electrodeposition method using spermidine as a shape directing agent. The biosensor was fabricated by immobilization of a Leishmania major specific DNA probe onto gold nanoleaves, and methylene blue was employed as a marker. Hybridization of the complementary single stranded DNA sequence with the biosensor under the selected conditions was then investigated. The biosensor could detect a synthetic DNA target in a range of 1.0×10-10 to 1.0×10-19molL-1 with a limit of detection of 1.8×10-20molL-1, and genomic DNA in a range of 0.5-20ngμL-1 with a limit of detection of 0.07ngμL-1. The biosensor could distinguish Leishmania major from a non-complementary-sequence oligonucleotide and the tropica species with a high selectivity. The biosensor was applicable to detect Leishmania major in patient samples.
