Closed filter system, coating

PERSONAL PROTECTION wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls use dust and splash proof safety goggles a closed system of local exhaust ventilation is recommended to control emissions at the source and to prevent dispersion into general work area wear positive pressure self-contained breathing apparatus in oxygen deficient atmospheres for extra personal protection, a P2 filter respirator for harmful particles should be worn maintain eyewash fountains and quick-drench facilities in work area. 

Since the optofluidic imaging systems are lens-free, after the source and the object plane, the only other portion is the sensor. Normally the sensor is made the base of the microfluidic platform, so that it can be as close to the object plane as possible. A CMOS sensor is used such that apertures are punched on a glass slide that acts as a cover for the sensor and each aperture is punched such that it corresponds to one pixel on the sensor. Since it is a semiconductor device, it can be directly coupled to an image retriever like a computer, as soon as the image is acquired, for further processing. Filters can also be coated over the sensors especially while working with...
