“…It was found that the LOD of 3.9 pg/ml having linearity ranging from 0.001-1 ng ml −1 was attained [Fig. 13A Recently, Li et al 114 has constructed novel capillary monolithic 3D structural based SERS platform comprising Au@cDNA@Ag@Cyanine 3-aptamer nanoparticles (Au@cDNA@Ag@Cy3-Apt NPs) for BPA determination. The developed SERS based aptasensor involve the combined efforts of both aptamer-affinity recognition and in-capillary SERS approach, in which the capillary monolith benefits are integrated with aptamer selectivity and excellent SERS characteristics of silvergold NPs.…”

Recent research has focused on detection of bisphenol A (BPA), a prominent endocrine disruptor (EDC), because of major health concerns. It is employed as a raw material to produce harmful environmental pollutants such as polycarbonate plastics, thermal papers, and epoxy resins. BPA is a renowned EDC that mimics oestrogen hormone and disrupts both endocrine and reproductive systems. Although many analytical methods have been used to detect BPA, using aptamers as a bioreceptor has shown to be fairly promising in this respect because of its inexpensiveness, speed, high sensitivity, and specificity and portable benefits. Quantum dots, metal associated oxide nanocomposites, metal-organic framework, polymer nanocomposites, carboneous nanomaterials, and molecularly-imprinted polymers were all proposed as aptamer-based sensors for the sensitive screening of BPA. This review summarises advancements done in the aptasensors area since 2011 for determination of BPA in food products, water samples, and human body fluids using different transducers, including electrochemical, optical, and other techniques. In addition, we delve into the challenges and potential opportunities associated with aptasensors specifically tailored for BPA recognition. We hope it will serve as a valuable resource for researchers and scientists offering insights to guide future studies and advancements in the new aptasensors development for BPA detection.
