Development of molecularly imprinted polymers-surface-enhanced Raman spectroscopy/colorimetric dual sensor for determination of chlorpyrifos in apple juice

Molecularly imprinted polymers for sample preparation and biosensing in food analysis: Progress and perspectives

“…The development of surface enhanced Raman spectroscopy (SERS) biosensors has generated huge interest in the research community due to their high sensitivity and ability to perform multiplex detection (Bantz et al, 2011;Rodriguez-Lorenzo et al, 2012). In food analysis, several papers have described the use of these types of sensors with MIP receptors (Feng et al, 2017;Feng and Lu, 2015). In 2013, bisphenol A molecularly imprinted gold nanoparticles were made as the substrate for a SERS biosensor which was capable of detecting bisphenol A in beverages with a detection limit of 0.12 mg L −1 (Xue et al, 2013).…”

A novel sensing layer based on metal–organic framework UiO-66 modified with TiO2–graphene oxide: application to rapid, sensitive and simultaneous determination of paraoxon and chlorpyrifos

“…CPF is moderately toxic to humans as a neurotoxin and endocrine disruptor and is especially harmful to pregnant women and infants. 9 Therefore, over recent years significant effort has gone into the development of efficient and sensitive methods such as liquid or gas chromatography (HPLC or GC) for detection of these pesticides. However, these techniques are not appropriate for in situ and real-time detection and require expensive equipment and highly trained personnel for their operation as well as timeconsuming extraction and cleanup steps.…”

Luminol Chemiluminescence Catalyzed by Silver Nanoparticles for the Sensitive Determination of Penicillamine

“…Silver and gold nanoparticles have been considered as hallmark during exploitation of Surface Enhanced Raman Spectroscopy, a technique that opened new avenues in research allowing detection of agrochemicals, biochemical molecules and toxins at ultra-trace levels and making it an important diagnostic technology [11][12][13][14][15][16][17]. Moreover, silver is known for its high toxicity to a wide range of microorganisms, this has, in turn, driven lots of attention to investigate AgNPs as a promising antimicrobial agent [18,19].…”
