Abstract:A sensitive and facile electrochemical immunosensor for ultrasensitive detection of hepatitis B surface antigen (HBsAg) was designed, which was based on platinum nanoparticle decorated amino silane functionalized montmorillonite (Pt-NH 2 -MMT). As it is a luminosilicate clay mineral, the advantages of montmorillonite (MMT), such as a large specific surface area, good adsorption/ion exchange capacity and innocuousness, endow Pt-NH 2 -MMT with better sensing performance. The platinum nanoparticles (Pt NPs) also … Show more
“…An electrode is a vital element in an electrochemical biosensor, which is designed to transform the recognition of a biological molecule into an easily quantiable electrical signal. 12,13 Screen printing technology is a well-developed method and widely used to fabricate disposable and economical electrochemical sensors. Screen-printed electrodes (SPEs) satisfy the need for highly reproducible, sensitive and cost-effective detection methods.…”
To explore the possibility of achieving rapid and in situ detection of aflatoxin B1 (AFB1), a portable biosensing instrument consisting of an impedance detector and a 3D-printed USB-compatible sensor chip was developed.
