Microdialysis: its role in diagnostics and in understanding nutrition

Probe Scientific Limited, Bedford, United Kingdom


Microdialysis is at the forefront of tissue monitoring techniques. The co-development of microdialysis and electrochemical detection during the 1970s and 80s provided neurochemists with unprecedented capabilities to study brain chemistry and neuropharmacology. The slow adoption of microdialysis for clinical practice reflects our lack of knowledge and the habitual use of blood sampling for diagnostics. However, as more diabetics move from 'finger-sticking' to wearable biosensors for continuous monitoring, the limitations of conventional blood sampling become clearer and the search is on for better tools to understand the dynamic flux occuring within the body. Microdialysis with online biosensors is one such tool and provides a new impetus in the field of diagnostics and nutrition. This presentation outlines developments and provides examples of new capabilities.

Electrochemical microbiosensors for medical monitoring

Institute of Analytical Sciences, Claude Bernard University Lyon 1


Biosensors are devices including a recognition part of biological origin associated to a transduction part, allowing the transduction effect of the recognition of the target specie into an electrical or optical signal. In this presentation, two types of electrochemical biosensors will for medical monitoring will be presented:

-          Enzymatic field-effect transistors for monitoring urea and creatinine concentration during hemodialysis, for improving patients’ comfort and dialysis efficiency [1].

-          conductometric biosensor for the generic, rapid and sensitive detection of Gram-negative bacteria, bacterial contamination of platelet concentrates being the highest infectious risk in transfusion despite the current preventive strategies, in developed countries [2,3].
