Liposomes have been widely applied as carriers of molecules in the fields of nanodevices, drug delivery and gene delivery, as well as a mimic for cell membranes. In the biosensor field, liposomes find special application in signal amplification, due to their excellent carrier properties for encapsulation of signal marker compounds across a wide ...

AbstractIn this paper we proposed a palladium(II) biosensor. The biosensor is based on determining of interactions between palladium(II) and metallothionein modified hanging mercury drop electrode by means of differential pulse voltammetry. We studied influence of two supporting electrolytes (potassium or sodium chloride) on the signals of the ...

Chemical Society Reviews, 2010
Electrochemical biosensors combine the sensitivity of electroanalytical methods with the inherent bioselectivity of the biological component. The biological component in the sensor recognizes its analyte resulting in a catalytic or binding event that ultimately produces an electrical signal monitored by a transducer that is proportional to analyte ...

Biosensors are sensors in which biomolecular interactions are used as sensing reactions. Biomolecular interactions, when combined with a microcantilever platform, can produce an extremely powerful biosensing design. The resonance frequency of a microcantilever shifts sensitively due to mass loading from molecular interaction as in the case of any ...

Current Opinion in Biotechnology, 1996
Over the past 18 months, our understanding of the chemistry and engineering principles of amperometric biosensors, including bioaffinity sensors, has deepened. In addition, several novel amperometric biosensors have been commercialized and progress has been made in the design of subcutaneous sensors, particularly those for glucose.

Gravimetric transducers produce a signal based on a change in mass. These transducers can be used to construct gas sensors or biosensors using odorant binding proteins (OBPs) as recognition elements for small volatile organic compounds. The methods described in this chapter are based on the immobilization of the OBPs onto functionalized (activated ...
