TiO2/AgNPs SERS substrate for the detection of multi-molecules with a self-cleaning and high enhancement factor using the UV-induced method

Mu Jiang et al.

Summary: An ultraviolet light-induced method was used to grow silver nanoparticles (AgNPs) on the surface of titanium dioxide (TiO2) nanospheres and achieve self-cleaning function. The TiO2/AgNPs composite samples were prepared as surface-enhanced Raman scattering (SERS) substrates by adjusting the duration of UV light exposure. The electromagnetic distribution and theoretical enhancement factor of TiO2/AgNPs were analyzed through simulation software. The samples exhibited a detection limit lower than 10(-12) mol/L and an analytical enhancement factor (AEF) of approximately 6.8x10(10) for the Rhodamine 6G (R6G) molecule under a 10-minute UV light-induced duration. Additionally, the samples showed self-cleaning functionality and demonstrated stability and repeatability for up to 5 cycles.

Hybrid Surface-Enhanced Raman Scattering Substrates for the Trace Detection of Ammonium Nitrate, Thiram, and Nile Blue

Jagannath Rathod et al.

Summary: In this study, we fabricated and evaluated hybrid surface-enhanced Raman scattering (SERS) substrates using laser ablation and chemical methods for the trace-level detection of various analyte molecules. The laser-processed silver structures showed reasonably good enhancements in the Raman signal intensities, while the Au nanostar-decorated laser-processed silver substrate exhibited higher enhancement compared to the plain laser-processed silver and Au nanostar-loaded silver substrates.

The Prevalence of Opioids in US Drinking Water Sources Detected Using Direct-Injection High-Performance Liquid Chromatography-Tandem Mass Spectrometry

Christopher S. Skaggs et al.

Summary: Contamination of water sources with active pharmaceutical ingredients (APIs), including opioids, has become more common in recent years. This study developed and validated a method for the ultratrace determination of fentanyl, hydrocodone, and codeine in drinking water using high-performance liquid-chromatography tandem mass spectrometry (HPLC-MS/MS). The method was used to test drinking water samples from 53 locations in the US, with hydrocodone and codeine detected in approximately 40% of the samples tested. Codeine was detected at higher concentrations than hydrocodone, while fentanyl was not detected in any samples. These findings raise concern and highlight the importance of continued monitoring of these drugs in drinking water.

The Origin of Mo2C Films for Surface-Enhanced Raman Scattering Analysis: Electromagnetic or Chemical Enhancement?

Chang Ji et al.

Summary: This study investigates the origin of surface-enhanced Raman scattering (SERS) using a two-dimensional (2D) semimetal material, molybdenum carbide (Mo2C) film, and demonstrates that its enhancement effect is of chemical origin. The study also proposes doping strategies to optimize the SERS sensitivity of Mo2C.

Coupling of plasmonic nanoparticles on a semiconductor substrate via a modified discrete dipole approximation method

Diogo F. Carvalho et al.

Summary: Understanding the plasmonic coupling between metallic nanoparticles (NPs) in a 2D array and the effect of a semiconductor substrate is crucial for optimizing optoelectronic structures. This study presents a simple semi-analytical approach based on the discrete dipole approximation (DDA) to simulate the far-field and near-field properties of NP arrays, taking into account particle coupling and the presence of a semiconductor substrate. The method is validated for Ag NP dimers and single Ag NPs on a GaN substrate, and then applied to square and random arrays of Ag NPs. It is found that increasing the NP surface density on a GaN substrate results in a redshift of the dipolar resonance frequency and enhanced near-field properties. The single dipole approach used in this model allows for efficient computational times, making it advantageous for predicting optical properties in large NP arrays on semiconductor substrates for various applications.

Inkjet Printing of Ag and Polystyrene Nanoparticle Emulsions for the One-Step Fabrication of Hydrophobic Paper-Based Surface-Enhanced Raman Scattering Substrates

Natercia C. T. Martins et al.

Summary: This study introduces a general method to fabricate hydrophobic paper-based SERS substrates and optimizes their performance by controlling factors such as the ratio of nanoparticles and the number of printing layers. The selected substrates showed good SERS performance for various analytes, with specific analysis conducted on the pesticide thiram. The one-step fabrication method is suggested to enhance the SERS performance of the paper substrates through nanoscale features of the hydrophobic coating.
