Highly sensitive biosensor based on graphene–poly (3-aminobenzoic acid) modified electrodes and porous-hollowed-silver-gold nanoparticle labelling for prostate cancer detection

Recent studies show that electrochemical biosensors offer simple, robust and low-cost solution for point-of-care applications. To meet rigorous requirements of early disease diagnosis and other medical applications, nanomaterials have been investigated to increase sensitivity and selectivity of electrochemical sensors. Herein, we successfully developed graphene-poly(3-aminobenzoic acid) (GP-P3ABA) nanomaterial-conductive polymer composite for...
