An array of individually addressable micro-needles for mapping pH distributions.

Bioelectrochemical Imaging with Micro/Nanoelectrode Systems

This paper report a novel approach for bioimaging with two different micro/nanoelectrode systems; i. e., scanning electrochemical microscopy (SECM) and individually addressable microelectrode array. Hybrid SECM systems with shear-force or ion-conductance feedback distance control were applied to high resolution and simultaneous imaging of topography and electrochemical responses of enzymes and ...

Addressable Electrode Array Device Incorporated with Ida Electrodes for Biological Analyses

In the past decade, several kinds of microelectrode arrays have been applied to chemical and biological analyses. These electrochemical array devices have substantial advantages, including rapid response time and qualitative and quantitative detection. Among the various systems that are based on electrochemical detection, individually addressable electrode arrays have been used for simultaneous...

Fabrication of conical microneedles array using photolithography

Background and Aim: Microneedle technology has led to huge changes in the field of drug delivery medicine. Using microneedles, the drug can be injected locally, painlessly, and in very low and controlled doses with high precision. Local drug delivery through the skin with microneedles has many advantages over other methods of drug delivery. In this method, the drug does not enter the gastrointe...

Micro-LED arrays: a tool for two-dimensional neuron stimulation

Stimulating neuron cells with light is an exciting new technology that is revolutionizing the neurosciences. To date, due to the optical complexity that is involved, photostimulation has only been achieved at a single site using high power light sources. Here we present a GaN based micro-light emitting diode (LED) array that can open the way to multi-site photostimulation of neuron cells. The d...
