What is it about?

Gold nanoparticles in polypyrrole matrix enhance enzymatic electrochemical biosensing, enhancing acetylcholinesterase's enzyme activity. Remarkable sensitivity improvement of 145 % based on electrochemical techniques. A wide sensing range was also achieved, increasing versatility and accuracy across various concentrations. Finally, femtomolar detection of the pesticide methyl parathion was achieved.
