A flow injection system using electrochemical biosensor for in-time monitoring of lactic acid at the skin's surface was fabricated and tested. The system consists of a microfluidic ‘skin-patch’ sampling device and an electrochemical biosensor using a carbon graphite electrode. In order to enhance the stability of monitoring, lactic acid excreted at the skin's surface was directly solved into the career...
Amperometric biosensors are complex systems and they require a combination of technologies for their development. The aim of the present work is to propose a new approach in order to develop nanostructured biosensors for the real-time detection of multiple metabolites in cell culture flasks. The fabrication of five Au working electrodes onto silicon substrate is achieved with CMOS compatible microtechnology...
The objective of this work is the systematic study of the use of electrochemical readout for advanced diagnosis and drug monitoring. Whereas to date various electrochemical principles have been studied and successfully tested, they typically operate on a single target molecule and are not integrated in a full data analysis chain. The present work aims to view various sensing approaches and explore...
A novel single-chip and multiplexed read-out circuit for multi-electrode electrochemical sensors, in standard 0.18 μm UMC CMOS technology, is presented. The circuit is a part of a fully-integrated biochip (in design) for the detection of multiple metabolites. The proposed topology is based on the potentiostat approach, and it is devoted to detect currents within the range of 250 pA 650...
The paper presents an innovative distributed measurement system for wine fermentation monitoring. The system intelligence is distributed among some Local Measurement Units (LMU) and a Manager Unit (MU). LMU's, made by a biosensor with its conditioning circuit plus a signal acquisition and processing module, can be integrated in complex multi-sensor schemes for process monitoring under control of a...
