This work presents a novel filter paper-based method using surface-enhanced Raman spectroscopy (SERS), for detecting polystyrene nanoplastics (PSNPs). The SERS system used a simple mixture of spherical Au nanoparticles (AuNPs) and 20 nm nanoplastics deposited onto a filter paper which offered a detection limit of 10 μg mL with a sample volume of 50 μL, and in a rare case 5.0 μg mL (with four aliquits of 50 μL).

Applied Science Department, The NorthCap University, 122017, Gurugram, Haryana, India.
For the first time, a TiCT-MXene and poly (3, 4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT: PSS) composite-modified electrode has been developed for electrochemical detection of the bilirubin (BR) by molecularly imprinted ortho-phenylenediamine (o-PD). BR is a biomarker for liver-related diseases. High levels of BR imply liver dysfunction; hence, its exact and rapid measurement is indispensable to its immediate diagnosis and treatment.

Development of a multiplexed and sensitive biosensing platform is a priority for public health security. We report a micropore resistance counting platform based on polystyrene microsphere size-based encoding and Argonaute (CbAgo) decoding for multiplexed and ultrasensitive detection. Initially, we constructed a target DNA-modified polystyrene microsphere coding system based on micropore resistance counting.

The lining cavities in tunnels have strong concealment and pose significant risks, seriously affecting tunnel operational safety. Therefore, it is necessary to develop efficient and high-precision detection techniques for tunnel lining cavities. In this study, concrete slabs with different parameter cavities were selected as the research object, and experiments on remote detection using Laser Doppler Vibrometry were conducted.
