In a study published in Analytical Chemistry, researchers have designed a microfluidic photoelectrochemical (PEC) aptasensor using photoactive AgBr/CuBi2O4 (ACO) composites for rapid and ultrasensitive detection of environmental contaminants.
Keeping harmful compounds out of the food supply chain is a key factor when ensuring consumer safety. Now, researchers at Ural Federation University and Potovsky Institute of Organic Synthesis, Russia, have developed an advanced ultrasensitive electrochemical sensor that can detect nitrobenzene in commercial honey solutions.
