Abstract
Nanomedicine is promising for disease prevention and treatment, but there are still many challenges that hinder its rapid development. A major challenge is to efficiently seek candidates with the desired therapeutic functions from tremendously available materials. Here, we report an integrated computational and experimental framework to seek alloy nanoparticles from the Materials Project library for antibacterial applications, aiming to learn the inverse screening concept from traditional medicine for nanomedicine. Because strong peroxidase-like catalytic activity and weak toxicity to normal cells are the desired material properties for antibacterial usage, computational screening implementing theoretical prediction models of catalytic activity and cytotoxicity is first conducted to select the candidates. Then, experimental screening based on scanning probe block copolymer lithography is used to verify and refine the computational screening results. Finally, the best candidate AuCu3 is synthesized in solution and its antibacterial performance over other nanoparticles against S. aureus and E. coli. is experimentally confirmed. The results show the power of inverse screening in accelerating the research and development of antibacterial nanomedicine, which may inspire similar strategies for other nanomedicines in the future.

[PMID: 36875960 PMCID: PMC9975142 DOI: 10.1007/s13205-023-03516-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Accepted: 02/13/2023] [Indexed: 03/06/2023] Open
Abstract
Plant growth regulators tagged on metallic oxide nanoparticles (NPs) may function as nanofertilizers with reduced toxicity of NPs. CuO NPs were synthesized to function as nanocarriers of Indole-3-acetic acid (IAA). Powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) revealed 30.4 nm size of NPs and sheet-like structure, respectively, of CuO-IAA NPs. Fourier-transform infrared spectroscopy (FTIR) confirmed CuO-IAA formation. IAA-decorated CuO NPs enhanced the physiological parameters of Chickpea plants, i.e., root length, shoot length, and biomass compared to naked CuO NPs. The variation in physiological response was due to change of phytochemical contents in plants. Phenolic content increased up to 17.98 and 18.13 µgGAE/mg DW at 20 and 40 mg/L of CuO-IAA NPs, respectively. However, significant decrease in antioxidant enzymes' activity was recorded compared to control. Presence of CuO-IAA NPs increased the reducing potential of plants at higher concentration of NPs, while decrease in total antioxidant response was observed. This study concludes that IAA conjugation to CuO NPs reduces toxicity of NPs. Furthermore, NPs can be explored as nanocarriers for plant modulators and slow release in future studies.

Abstract
Recently, the design and biosynthesis of metallic nanoparticles (NPs) have drawn immense interest, but their very specific function and secondary toxic effects are major concern towards commercial application of NPs. That's why environment-friendly (nontoxic) NPs having multiple functions are extremely important. Herein, we report the mechanism of biosynthesis of mono and bimetallic (Au-Ag) alloy NPs and study their multifunctional (antioxidant, antifungal and catalytic) activity and ecotoxicological property. AgNPs exhibit phytotoxicity (at 100 μg/ml) on morphological characteristics of Lentil (during germination), while alloy and AuNPs are non-toxic (up to 100 μg/ml). In-vitro antioxidant response using DPPH methods reveals that alloy NPs (IC50 = 55.8 μg/ml) possesses better antioxidant activity compared to the monometallic NPs (IC50 = 73.6-82.6 μg/ml). In addition, alloy NPs displayed appreciable antifungal efficacy against a plant pathogenic fungus Gloeosporium musarum by structural damage to hyphae and conidia of the fungus. The catalytic performance of NPs for degradation of chlorpyriphos (CP) pesticide reveals that alloy NPs is more efficient in terms of rate constant (k = 0.405 d-1) and half-life (T50 = 1.71 d) compared to the monometallic counterparts (k = 0.115-0.178 d-1; T50 = 3.89-6.04 d). Degradation products of CP (3,5,6-trichloropyridinol and diethyl thiophosphate) are confirmed using mass spectrometry and based on that a degradation pathway has been suggested. Thus, these sustainable and ecological safe biogenic (Au-Ag) alloy NPs promise multiple applications as an antioxidant in the pharmaceutical sector, as a fungicide for disease control in agriculture, as a catalyst for remediation of toxic pollutants and in other pertinent areas.

ARTIFICIAL CELLS, NANOMEDICINE, AND BIOTECHNOLOGY 2021; 49:450-460.

Abstract
Zinc oxide nanoparticles (ZnO-NPs) have been produced by physical and chemical methods. Here, the comparative evaluation of both chemically-synthesised ZnO-NPs (C-ZNPs) and in-vitro cultured S. marianum mediated green-synthesised ZnO-NPs (G-ZNPs) were investigated on seed germination frequency, root and shoot growth, callus induction and biochemical profile of medicinally important plant Silybum marianum. Of all the treatments, callus-mediated ZnO-NPs gave optimum results for seed germination (65%), plantlet's root length (4.3 cm), shoot length (5.3 cm) and fresh and dry weights (220.4 g L-1 and 21.23 g L-1, respectively). Similarly, the accumulation of phenolic (12.3 µg/mg DW) and flavonoid (2.8 µg/mg DW) contents were also enhanced in callus cultures treated with G-ZNPs. We also observed maximum antioxidant activity (99%) in callus cultures treated with G-ZNPs, however, in case of plantlets, these activities were found highest for in-vitro whole plant-mediated ZnO-NPs. Moreover, G-ZNPs also enhanced total protein content (265.32 BSAE/20g FW) in callus cultures. G-ZNPs were further assessed for their effects on several multidrug resistant bacterial strains and human liver carcinoma (HepG2) cells and our findings revealed that callus extracts treated with G-ZNPs show ameliorated antibacterial (highest zone of inhibition (19 mm) against Klebsiella pneumonia) and anticancer (highest cytotoxicity of 64%) activities.

Abstract
Nanoparticles possess some unique properties which improve their biochemical reactivity. Plants, due to their stationary nature, are constantly exposed to nanoparticles present in the environment, which act as abiotic stress agents at sub-toxic concentrations and phytotoxic agents at higher concentrations. In general, nanoparticles exert their toxicological effect by the generation of reactive oxygen species to which plants respond by activating both enzymatic and non-enzymatic anti-oxidant defence mechanisms. One important manifestation of the defence response is the increased or de novo biosynthesis of secondary metabolites, many of which have commercial application. The present review extensively summarizes current knowledge about the application of different metallic, non-metallic and carbon-based nanoparticles as elicitors of economically important secondary metabolites in different plants, both in vivo and in vitro. Elicitation of secondary metabolites with nanoparticles in plant cultures, including hairy root cultures, is discussed. Another emergent technology is the ligand-harvesting of secondary metabolites using surface-functionalized nanoparticles, which is also mentioned. A brief explanation of the mechanism of action of nanoparticles on plant secondary metabolism is included. Optimum conditions and parameters to be evaluated and standardized for the successful commercial exploitation of this technology are also mentioned.

Eruca sativa Meal against Diabetic Neuropathic Pain: An H 2S-Mediated Effect of Glucoerucin. Molecules 2019; 24:molecules24163006.

Abstract
The management of pain in patients affected by diabetic neuropathy still represents an unmet therapeutic need. Recent data highlighted the pain-relieving efficacy of glucosinolates deriving from Brassicaceae. The purpose of this study was to evaluate the anti-hyperalgesic efficacy of Eruca sativa defatted seed meal, along with its main glucosinolate, glucoerucin (GER), on diabetic neuropathic pain induced in mice by streptozotocin (STZ). The mechanism of action was also investigated. Hypersensitivity was assessed by paw pressure and cold plate tests after the acute administration of the compounds. Once bio-activated by myrosinase, both E. sativa defatted meal (1 g kg−1 p.o.) and GER (100 µmol kg−1 p.o., equimolar to meal content) showed a dose-dependent pain-relieving effect in STZ-diabetic mice, but the meal was more effective than the glucosinolate. The co-administration with H2S scavengers abolished the pain relief mediated by both E. sativa meal and GER. Their effect was also prevented by selectively blocking Kv7 potassium channels. Repeated treatments with E. sativa meal did not induce tolerance to the anti-hypersensitive effect. In conclusion, E. sativa meal can be suggested as a new nutraceutical tool for pain relief in patients with diabetic neuropathy.

Abstract
Nanotechnology is one of the advance technologies that almost found implications in every field of science. The importance is due to the unique properties of nanoparticles. In this study, bimetallic alloys of copper (Cu) and gold (Au) were tested in submerge root cultures of Stevia rebaudiana for production of biomass and secondary metabolites. A known amount of inoculum roots were submerged in liquid Murashige and Skoog medium containing combination of naphthalene acetic acid (NAA; 0.5 mg l-1) and different ratios of nanoparticles (NPs). NAA augmented medium was used as control. The addition of nanoparticles (30 µg l-1) stimulated biomass accumulation (1.447 g/flask) on 27th day of log phases. The maximum total phenolics content (TPC; 16.17 mg/g-DW) and total flavonoids content (TFC; 4.20 mg/g-DW) were displayed using AuCu-NPs (1:3) and NAA. The same combinations enhanced total phenolic production (TPP; 116 mg/L) and total flavonoid production (TFP; 29.5 mg/L) in submerged cultures. A strong correlation was observed between phenolics, flavonoids and dry biomass. Moreover, maximum 1, 1-diphenyl-2-picrylhydrazyl (DPPH) activity of 79% was displayed by addition of AuCu (1:3) nanoparticles. In conclusion, nanoparticles application has shown a positive effect in enhancing biomass and secondary metabolites production in adventitious root cultures of Stevia rebaudiana.

Abstract
Nanoparticles have been used in many areas of biotechnology. In this study, an alternative surface sterilisation method was established for plant tissue cultures. Silver nanoparticles synthesised via green synthesis were used for the surface sterilisation of Lamiaceae seeds (Salvia farinecae, Ocimum basilicum - Large Leaf Italian, Thymus vulgaris, Ocimum basilicum var. purpurascens). Water extracts of dried Alkanna tinctorum rhizomes and Syzygium aromaticum flowers were utilised in the bioreduction of silver ions. The seeds were exposed to 0, 1, 7, 14 and 28 day-old colloidal solutions of silver nanoparticles and their effects on germination and surface sterilisation were determined. Fresh (0 and 1 day-old) colloidal solutions of silver nanoparticles were found very effective on surface sterilisation (100%). Moreover, they showed no negative effect on both germination and morphology of plantlets. It was shown that silver nanoparticles can be used as a surface sterilisation agent and they have no adverse effects on seed germination and in vitro plantlet growth.
