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].

Presentation

1.       PalmSense

The aim of PalmSens is:

·   To provide developers and producers of electrochemical sensors with portable, battery powered or low-cost and fully programmable electronic devices. These devices can be modified according to specifications given by users.

·  To promote the use of electrochemical sensors outside dedicated laboratories, by supplying handheld instruments as well as specific electrochemical sensors.

·  To provide researchers with electrochemical instruments at reasonable costs.

2.       eDAQ (http://www.edaq.com/)

eDAQ manufactures laboratory instruments and data acquisition systems for electrochemistry, chromatography, flow analysis, contactless conductivity, sensor recording, electrochemical impedance, teaching and research.

eDAQ recording systems are 'plug-and-play' with USB connection to your computer! View our screencast videos showing to use the software.

Fully software-controlled potentiostats and isoPods (pH, conductivity, temperature, etc) can be used in conjunction with our e-corder systems, as can many third party instruments and electrodes, transducers & accessories.

3.       BASI (http://www.basinc.com)      

BASi provides drug developers with superior scientific research and innovative analytical instrumentation, which saves time, saves money, and saves lives, to bring revolutionary new drugs to market quickly and safely.

4.       C-Tech innovation  (https://www.ctechinnovation.com)

C-Flow is a range of electrochemical cells and systems produced by C-Tech Innovation, a specialist in electrochemical technology based in the UK. With 50 years’ experience in providing technology solutions and equipment, C-Tech has a deep institutional understanding of electrochemistry and the needs of re-searchers, engineers and technicians working in the field. Dissatisfied with the solutions currently on the market, C-Tech has poured those years of expertise into creating the equipment they wanted to use – the most versatile and easy-to-use electrochemical cells and systems in the world.
