Use of a highly sensitive, selective capacitive biosensor is reported for label-free, real-time, easy and rapid detection of trypsin by using the micro contact imprinting method.
A strategy for the detection of aflatoxin B1 using a capacitive biosensor has been studied. The use of proteins for the generation of sites with high specificity against aflatoxin B1 are produced via bioimprinting.
In this study, a label-free, selective and sensitive microcontact imprinted capacitive biosensor was developed for
the detection of Escherichia coli.
Prostate-specific antigen (PSA) is an important biomarker for diagnosis and prognosis of prostate cancer. Herein, microcontact PSA-imprinted surface plasmon resonance (SPR) sensor chip was developed for sensitive, real-time detection of PSA.
Capacitive binding assays have long been considered highly sensitive. The underlying method includes sending short potential pulses and then registering the current. With the introduction
of current pulses and registration of potential responses, the stability improved significantly.
A capacitive biosensor was used for detection of aflatoxin B1. Two different methods for cleaning gold electrodes were evaluated using cyclic voltammetry in the presence of ferricyanide as redox couple. The methods involve use of a sequence of cleaning steps avoiding the use of Piranha solution and plasma cleaner.
An affinity sensor based on capacitive transduction was developed to detect a model compound, metergoline, in a continuous flow system. This system simulates the monitoring of low-molecular weight organic compounds in natural flowing waters, i.e. rivers and streams.
