The levels of aspartate aminotransferase (AST/GOT) and alanine aminotransferase
(ALT/GPT) in serum can help people diagnose body tissues especially the heart and the …

Biosensors, combining a selective biological recognition element and a sensitive
transducer, are versatile analytical tools applied more and more in different fields, such as …

A homogeneous chitosan–ferrocene/graphene oxide/glucose oxidase (CS–Fc/GO/GOx)
nanocomposite film was successfully constructed as a novel platform for the fabrication of …

Development of reagentless biosensors implies the tight and functional immobilisation of
biological recognition elements on transducer surfaces. Specifically, in the case of …

We present a flexible microsensor, based on a polymer substrate, for multiparametric,
electrochemical in vivo monitoring. The sensor strip with a microelectrode array at the tip …

GABA and glutamate sampled from the brain by microdialysis do not always fulfill the classic
criteria for exocytotic release. In this regard the origin (neuronal vs. astroglial, synaptic vs …

Chemical signalling underlies every function of the nervous system, from those of which we
are unaware, for example, control of the heart, to higher cognitive functions, such as …

Glutamate (Glu) is recognized as a vital neurotransmitter released via vesicular exocytosis
and plays important roles in many physiological processes. Microelectrode amperometry …

Ferrocene redox polymers based on the coupling of ferrocenecarboxaldehyde to both linear
and branched poly (ethylenimine)(PEI) have been prepared to investigate the effects of pH …

Brain-implantable microprobe arrays, 6.5 mm shaft-length, incorporating several recessed Pt
microelectrodes (50μm× 150μm) and an integrated Ag/AgCl reference electrode fabricated …
