Electrochemical aptasensor based on black phosphorus-porous graphene nanocomposites for high-performance detection of Hg2+

Aptamer-Based Potentiometric Sensor Enables Highly Selective and Neurocompatible Neurochemical Sensing in Rat Brain

“…Alternatively, the modification of electrochemical sensors with enzymatic or synthetic recognition receptors represents an effective approach to achieve discerning detection capabilities. Among these receptor materials, nucleic acid-based aptamers emerge as highly promising candidates for sensing applications, owing to their notable attributes of high specificity, binding affinity, and programmability. , The strategic incorporation of aptamers into electrode designs, such as carbon fiber electrodes (CFEs) , or field-effect transistors, , has yielded a remarkable class of neuroprobes renowned for their unparalleled selectivity. These aptamer-based neuroprobes facilitate real-time monitoring of a great panel of neurotransmitters within the living brains of animals.…”
