(While using j.Vitamin y.Treherne)Researchresearch interestsmy interests lie in observation cells, in health insurance and disease, by looking for the dynamics of living systems.Particularly, i been fascinated by following cell activity non invasively by sampling chemical profiles in the unstirred layers surrounding single cells and tissues.The unstirred layer is unexpectedly deep.In still culture medium estimates range up to 300m as well as flowing medium this layer can be 10s of microns in depth.There is ample volume for proving chemical gradients in the boundary layers that result from cell activity and ample space for deploying electrochemical sensors of micron diameters within these layers.Chemical signals are very secure, specially when backgrounds and/or competing chemicals are low in activity.But the truth is, instabilities in the electrode and the playback quality circuit frequently prevent extraction of useful data.Here a modulation course of action, called self referencing, is needed.With this method an electrochemical microelectrode records chemically dependent signals at djzine two positions and a differential is calculated.This results in a 1000 fold improvement in resolution over the same electrode in a static construction.Both potentiometric and amperometric sensors allow you, giving you high spatial and temporal fidelity.
