Recent advances in gold nanoparticle-based colorimetric aptasensors for chemical and biological analyses: supplementary materials

Aptasensors are amazing among many currently formed procedures due to their excellent particularity,

selectivity and responsiveness. These biosensors get more popular in combination with gold nanoparticles

(AuNPs) to detect chemical and biological molecules. The response of AuNPs by changing color provides a

simple explanation of outcomes. The authors review the recent developments in AuNP-based colorimetric

aptasensors designed to sense different chemical and biological molecules. They summarize the procedure

of AuNP-based detection and the ordinary instances of currently formed AuNP-based colorimetric

procedures. Furthermore, their uses for detecting different analytes based on analyte types are given

and the present challenges, overview, and positive views for forming new aptasensors are also regarded.
