This study reports the design and evaluation of a new synthetic receptor sensor based on amalgamation biomolecular recognition elements molecular imprinting to overcome some challenges faced by conventional protein imprinting. A thiolated DNA aptamer with established affinity for prostate specific antigen (PSA) was complexed PSA prior being immobilised surface gold electrode. Controlled electropolymerisation dopamine around complex served both entrap complex, holding in, or near to, it's...

Abstract Hollow microneedle devices as a technology for interstitial fluid extraction show promise the minimally invasive point‐of‐care detection of analytes. Despite increasing efforts toward on‐patch diagnostics, use hollow microneedles has been limited due to complexity caused by integrating with established diagnostic techniques. Herein, 3D printing method is utilized, provide low‐cost manufacturing custom‐designed devices, allowing easy integration lateral flow assays rapid and...
