Silver nanoparticle-decorated TiO2 nanotube array for solid-phase microextraction and SERS detection of antibiotic residue in milk

Recent advances in silver nanoparticle-based electrochemical sensors for determining organic pollutants in water: a review

“…Recently, they attracted great attention as optical probes for several organic pollutants because of their strong absorption band, which is very sensitive to the particle size, shape, and relative permittivity of the local environment, in the visible region of light 53 . AgNP-based optical sensors were reported for the detection of pesticides 20,[54][55][56][57][58][59] , organic dyes 60 , drugs [61][62] , nitro-aromatics 63 , and mycotoxins 64 . Electrochemical sensors, such as AgNP-based electrochemical sensors, are considered promising for detecting organic pollutants with sufficient sensitivity and selectivity compared with the optical sensors 65 .…”

A Wearable PVA Film Supported TiO2 Nanoparticles Decorated NaNbO3 Nanoflakes‐Based SERS Sensor for Simultaneous Detection of Metabolites and Biomolecules in Human Sweat Samples

“…[22] Jing et al studied the solid-phase microextraction and SERS detection of antibiotics in residue milk using the silver nanoparticles-decorated TiO 2 nanotube array as active substrate. [23] The bandgap of the TiO 2 reported for both rutile and anatase phases are 3.2 and 3.35 eV, respectively. Thus, TiO 2 has been used as a complex to enhance Raman scattering in biosensing applications.…”

Cu-Doped Boron Nitride Nanosheets for Solid-Phase Extraction and Determination of Rhodamine B in Foods Matrix

“…Solid-phase extraction (SPE), a sample pretreatment method, has been widely used to pretreat pesticides, antibiotics, and other chemical products [ 6 , 7 , 8 ] due to its excellent advantages, such as high efficiency and easy operation [ 9 ]. Additionally, the adsorption efficiency of SPE mainly depends on the interactions between packing adsorbents and analytes [ 10 , 11 ].…”
