SERS provides essential data regarding the interaction of molecules in drugs with DNA. In the present study silver nanoparticles were synthesized using a solution combustion method with urea as fuel. The prepared silver nanoparticles are rod like structure. Surface-enhanced Raman scattering (SERS) of N-(1-2-bromophenyl)-2-(2-nitrophenyl)ethyl)-4-methylbenzenesulfonamide (BrS) adsorbed on the silver nanoparticle was studied. The nRs and Raman spectral analysis reveal that the BrS adsorbed tilted orientation on the silver surface. Vibrational modes of nRs along with HF calculations are also performed to study the HOMO and LUMO behavior and vibrational features of BrS.

Blood carries some of the most valuable biomarkers for disease screening as it interacts with various tissues and organs in the body. Human blood serum is a reservoir of high molecular weight fraction (HMWF) and low molecular weight fraction (LMWF) proteins. The LMWF proteins are considered disease marker proteins and are often suppressed by HMWF proteins during analysis.

The development of a sensitive and selective silver nanoparticle assay for the quantitation of vitamin C (SNaP-C), as ascorbic acid (AA) and total ascorbic acid (TAA = AA + dehydroascorbic acid, DHAA), is described. Three assay parameters were investigated and optimized: (1) synthesis of silver nanoparticles (AgNPs) to produce a reliable enhanced localized surface plasmon resonance (LSPR) in the presence of specific added antioxidants; (2) ensuring long-term stability of AA and DHAA in aqueous solutions; and (3) SNaP-C assay conditions to allow for rapid analysis of samples (beverages) by monitoring the enhanced LSPR. The synthesis of AgNPs using soluble starch as a capping agent and d-arabinose as a reducing agent was optimized in a CEM Discover SP laboratory microwave.

Recently, researchers have used silver nanoparticles (AgNPs) coupled with humic acid (HA) as antimicrobial agents. Herein, AgNPs were prepared and coupled with humic acid for their antimicrobial activities. The as-prepared AgNPs coupled with humic acid (HA) were characterized by an atomic force microscope (AFM), X-ray powder diffraction (XRD), zeta potential, zeta sizer, Fourier-transform infrared (FT-IR) spectroscopy, and UV-VIS spectrophotometer.

Detection of biomolecules, Glutathione (GSH) in particular, is important because it helps assess antioxidant capacity, cellular protection, detoxification processes, and potential disease associations. Monitoring glutathione levels can provide valuable information about overall health and well-being. Many medical disorders have been connected to glutathione levels.
