Abstract
SERS (Surface Enhanced Raman Spectroscopy) is a new Raman spectroscopy which relies on Surface Plasmon Resonance (SPR) of metal nanoparticles. We have applied colloidal silver and gold nanoparticles as amplifier agents to enhance nucleotide Raman signals. It is observed that without these enhancing agents, it is impossible to investigate nucleotide spectrum due to weak Raman signals. Interaction mechanism of Melphalan, an anticancer drug with four nucleotides (Adenine, Cytosine, Guanine, Thymine) was investigated using SERS to detect and identify changes due to alkylating process in Raman spectra. After incubating Melphalan drug with nucleotides for 24 h at 37 °C, some changes occurred in SERS spectrum and interpretation of SERS spectra revealed the influence of the alkyl substitution on peaks and Raman shifts. After incubation of Melphalan with each nucleotide, intensity of relevant SERS signals assigned to Amid III group of Cytosine and Amid I of Thymine decreased significantly, confirming alkylating taking place. In this study, we also investigated the effect of nanoparticles type on nucleotide spectrum. We could not obtain useful information in the cases of guanine nucleotide. The SERS spectrum of Cytosine as an example of nucleotides in aqueous solution compared to solid state and results demonstrated that in solid state better signals were obtained than in liquid state.

Abstract
The study of nanoparticle motion has fundamental relevance in a wide range of nanotechnology-based fields. Molecular dynamics simulations offer a powerful tool to elucidate the dynamics of complex systems and derive theoretical models that facilitate the invention and optimization of novel devices. This research contributes to this ongoing effort by investigating the motion of one-end capped carbon nanotubes within an aqueous environment through extensive molecular dynamics simulations. By exposing the carbon nanotubes to localized heating, propelled motion with velocities reaching up to ≈0.08 nm ps-1 was observed. Through systematic exploration of various parameters such as temperature, nanotube diameter, and size, we were able to elucidate the underlying mechanisms driving propulsion. Our findings demonstrate that the propulsive motion predominantly arises from a rocket-like mechanism facilitated by the progressive evaporation of water molecules entrapped within the carbon nanotube. Therefore, this study focuses on the complex interplay between nanoscale geometry, environmental conditions, and propulsion mechanisms in capped nanotubes, providing relevant insights into the design and optimization of nanoscale propulsion systems with various applications in nanotechnology and beyond.

Abstract
Here, starch derivatives, i.e., sodium starch octenylsuccinate (OSA starch, hereinafter referred to as OSA), were employed as both reducing and stabilizing agents for the unique, inexpensive, and simple synthesis of gold nanoparticles (OSA-AuNPs) in an aqueous solution with gold salt. The obtained OSA-AuNPs were characterized by UV-vis spectrophotometry, transmission electron microscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. The catalytic activity of the obtained gold colloids was studied in the reduction of organic dyes, including methylene blue (C.I. Basic Blue 9) and rhodamine B (C.I. Basic Violet 10), and food coloring, including tartrazine (E102) and azorubine (E122), by sodium borohydride. Moreover, OSA-AuNPs were utilized as signal amplifiers in surface-enhanced Raman spectroscopy. The obtained results confirmed that gold nanoparticles can be used as effective catalysts in reduction reactions of selected organic dyes, as well as signal enhancers in the SERS technique.

Abstract
![]()
Surface-enhanced Raman spectroscopy (SERS) fingerprinting
is highly
promising for identifying disease markers from complex mixtures of
clinical sample, which has the capability to take medical diagnoses
to the next level. Although vibrational frequency in Raman spectra
is unique for each biomolecule, which can be used as fingerprint identification,
it has not been considered to be used routinely for biosensing due
to the fact that the Raman signal is very weak. Contemporary SERS
has been demonstrated to be an excellent analytical tool for practical
label-free sensing applications due its ability to enhance Raman signals
by factors of up to 108–1014 orders of
magnitude. Although SERS was discovered more than 40 years ago, its
applications are still rare outside the spectroscopy community and
it is mainly due to the fact that how to control, manipulate and amplify
light on the “hot spots” near the metal surface is in
the infancy stage. In this Account, we describe our contribution
to develop nanoachitecture
based highly reproducible and ultrasensitive detection capability
SERS platform via low-cost synthetic routes. Using one-dimensional
(1D) carbon nanotube (CNT), two-dimensional (2D) graphene oxide (GO),
and zero-dimensional (0D) plasmonic nanoparticle, 0D to 3D SERS substrates
have been designed, which represent highly powerful platform for biological
diagnosis. We discuss the major design criteria we have used to develop
robust SERS substrate to possess high density “hot spots”
with very good reproducibility. SERS enhancement factor for 3D SERS
substrate is about 5 orders of magnitude higher than only plasmonic
nanoparticle and more than 9 orders of magnitude higher than 2D GO.
Theoretical finite-difference time-domain (FDTD) stimulation data
show that the electric field enhancement |E|2 can be more than 2 orders of magnitude in “hot spots”,
which suggests that SERS enhancement factors can be greater than 104 due to the formation of high density “hot spots”
in 3D substrate. Next, we discuss the utilization of nanoachitecture
based SERS substrate for ultrasensitive and selective diagnosis of
infectious disease organisms such as drug resistance bacteria and
mosquito-borne flavi-viruses that cause significant health problems
worldwide. SERS based “whole-organism fingerprints”
has been used to identify infectious disease organisms even when they
are so closely related that they are difficult to distinguish. The
detection capability can be as low as 10 CFU/mL for methicillin-resistant Staphylococcus aureus (MRSA) and 10 PFU/mL for Dengue virus
(DENV) and West Nile virus (WNV). After that, we introduce exciting
research findings by our group on the applications of nanoachitecture
based SERS substrate for the capture and fingerprint detection of
rotavirus from water and Alzheimer’s disease biomarkers from
whole blood sample. The SERS detection limit for β-amyloid (Aβ
proteins) and tau protein using 3D SERS platform is several orders
of magnitude higher than the currently used technology in clinics.
Finally, we highlight the promises, major challenges and prospect
of nanoachitecture based SERS in biomedical diagnosis field.

Abstract
A nanostructured hybrid consisting of a high-density and uniform assembly of gold nanoparticles (AuNPs) on multiwalled carbon nanotubes (MWCNTs) is always desired and demanded in various applications. However, a simple, cost effective and highly efficiency method is required in the fabrication of MWCNTs-AuNPs nanohybrids. This study introduces a method where MWCNTs were functionalizing with nitric acid (HNO3) and sulphuric acid (H2SO4) in ratio of 1:3 v/v by using ultrasonication. These functionalized MWCNTs served as substrates for gold nanoparticle deposition. Later, it was pre-mixed with tri-sodium citrate (Na3C6H5O7.2H2O), next it was reacted with nobel metal (AuNPs) via the addition of chloroauric acid (HAuCl4) at various pH. When HAuCl4 was added to the reaction system, Au3+ was directly reduced at the surface of the MWCNTs and gold nanoparticles were assembled along the MWCNTs. Fourier Transform Infrared (FTIR), Thermogravimetric Analysis (TGA), Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray (EDX) analysis and dispersion test were used to characterize the MWCNTs/AuNPs nanocomposites. The fully functionalized MWCNTs using acid oxidation at 4 hour using ultrasonication were used in synthesis of nanohybrids, and the optimum gold yield on MWCNTs obtained at pH 4. Compared to other methods, these procedures require low temperature without involving the need of any catalyst or surfactant which results in a simple and efficient method for fabrication of gold nanoparticles on carbon nanotubes.

Abstract
We report a strategy to fabricate a rapid and stable surface-enhanced Raman scattering (SERS)-based hybrid nanomaterial using gold nanopopcorns attached single-walled carbon nanotubes (AuNP@f3-SWCNTs) for label-free detection and photothermal killing of bacteria. Herein, previously ester-functionalized single-walled carbon nanotubes (f1-SWCNTs) undergo 1,3-dipolar cycloaddition reaction with in-situ generated nitrile imine under Microwave (MW) irradiation to form a doubly ester terminated SWCNTs cycloadduct (f2-SWCNTs). The ester terminals are further modified with 4-aminothiophenol (4-ATP) under MW-irradiation to form thiol-terminated SWCNTs templates (f3-SWCNTs) that allow gold nanopopcorns (AuNPs) to covalently and uniformly attach at a minimum inter-particle distance thus yielding a hybrid nanomaterial (AuNP@f3-SWCNT) with good aqueous stability and abundant 'hotspots'. Consequently, monoclonal E. coli antibody-conjugated bioassays fabricated with our AuNP@f3-SWCNT substrates (mAb-AuNP@f3-SWCNT) rapidly detect E. coli in water with good selectivity and impressive SERS sensitivity. The detection limit of E. coli 49979, selected as a model to establish proof of principle, was found to be 1.0×102 CFU/mL. Furthermore, the AuNP@f3-SWCNT hybrid nanomaterial offers impressive photothermal pathogen killing effects. The synergy-type enhancement effect arising from the inherent noble properties of the respective components of the hybrid nanomaterial indicate that our AuNP@f3-SWCNT has the potential for further application in multiplex detection in samples.

Abstract
This article reviews the latest progresses regarding the applications of carbon nanotubes (CNTs), including single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs), as multifunctional nano-probes for biomedical imaging. Utilizing the intrinsic band-gap fluorescence of semi-conducting single-walled carbon nanotubes (SWNTs), fluorescence imaging in the near infrared II (NIR-II) region with enhanced tissue penetration and spatial resolution has shown great promise in recent years. Raman imaging based on the resonance Raman scattering of SWNTs has also been explored by a number of groups for in vitro and in vivo imaging of biological samples. The strong absorbance of CNTs in the NIR region can be used for photoacoustic imaging, and their photoacoustic signals can be dramatically enhanced by adding organic dyes, or coating with gold shells. Taking advantages of metal nanoparticle impurities attached to nanotubes, CNTs can also serve as a T2-contrast agent in magnetic resonance (MR) imaging. In addition, when labeled with radioactive isotopes, many groups have developed nuclear imaging with functionalized CNTs. Therefore CNTs are unique imaging probes with great potential in biomedical multimodal imaging.

Abstract
The highly sensitive and molecule-specific technique of surface-enhanced Raman spectroscopy (SERS) generates high signal enhancements via localized optical fields on nanoscale metallic materials, which can be tuned by manipulation of the surface roughness and architecture on the submicrometer level. We investigate gold-functionalized vertically aligned carbon nanotube forests (VACNTs) as low-cost straightforward SERS nanoplatforms. We find that their SERS enhancements depend on their diameter and density, which are systematically optimized for their performance. Modeling of the VACNT-based SERS substrates confirms consistent dependence on structural parameters as observed experimentally. The created nanostructures span over large substrate areas, are readily configurable, and yield uniform and reproducible SERS enhancement factors. Further fabricated micropatterned VACNTs platforms are shown to deliver multiplexed SERS detection. The unique properties of CNTs, which can be synergistically utilized in VACNT-based substrates and patterned arrays, can thus provide new generation platforms for SERS detection.
