Dopamine is a key catecholamine neurotransmitter and it has critical roles in the function of
the human central nervous system. Abnormal release of dopamine is related to neurological …

Over the last three decades, numerous aptamer-based biosensors have been reported. The
basis of these sensors is the selective binding of target analytes by aptamers. In the last few …

Detection of analytes by means of field-effect transistors bearing ligand-specific receptors is
fundamentally limited by the shielding created by the electrical double layer (the “Debye …

Aptamers are single‐stranded oligonucleotides that bind to targets with high affinity and
selectivity. Their use as molecular recognition elements has emerged as a viable approach …

Target-directed aptamer adsorption by gold nanoparticles (AuNPs) has been widely used to
develop label-free colorimetric biosensors. However, the potential interactions between …

A novel concept to improve the catalytic functions of nucleic acids (DNAzymes) is
introduced. The method involves the conjugation of a DNA recognition sequence (aptamer) …

It has been almost 30 years since the invention of Systematic Evolution of Ligands by
Exponential Enrichment (SELEX) methodology and the description of the first aptamers. In …

The last decade has witnessed tremendous advances in the use of graphene and graphene-
based nanocomposites for the fabrication of electrochemical (EC) sensors and biosensors …

Nondestructive neurotransmitter detection and real‐time monitoring of stem cell
differentiation are both of great significance in the field of neurodegenerative disease and …

Neurotransmitters as electrochemical signaling molecules are essential for proper brain
function and their dysfunction is involved in several mental disorders. Therefore, the …
