Microsensors for minimally invasive diagnostics

Describes the use of excimer lasers for microfabricating various minimally invasive biomedical sensor diagnostic devices. Excimer lasers are the brightest sources of controllable ultraviolet light yet developed by man. Currently excimer lasers are being used to fabricate some of the small structures that form the key technology of a number of medical probes and microsensors. Precision microdrilling with excimer lasers is now routine when making some of the delicate medical probes that measure in situ properties of blood in human arteries. The author discusses biomedical blood sensors, fibre grating sensors and microdisc array chemical sensors
