Different elements of the micro-FACS,  fabrication of opto-biochips, particle detection and  velocity measurement, and flow switching, are studied  in the present work. Biochips were fabricated by  casting polydimethylsiloxane (PDMS) on the masters  fabricated by direct laser-writing, and standard  lithography and dry etching. In a different approach,  biochips with integrated waveguides and microchannels  were fabricated photolithographically on glass  substrates using a negative photoresist, SU-8. In  these opto-biochips, two excitation waveguides  carrying two different wavelengths intersect the  microchannel at two points separated and one large  output waveguide carry fluorescence signals to a  single filtered detector. The velocities of the  microparticles were determined by the captured  fluorescence from the double peak. Simulations based  on beam propagation method were used to predict the  performance of the SU-8 waveguides and the intensity  at the two intersections has been compared with the  experimental results.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838389592\"\u003e\u003ch3\u003eAuthor''s summarizes his research work in the areas of Microfluidics and Photonics\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838389592","offer_id":39469296287837,"sku":"9783838389592","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/71dae7b2-6cd2-407c-a37b-1711947f5f59.jpg?v=1758875445","url":"https:\/\/shop.autorenwelt.de\/en\/products\/opto-biochips-for-microcytometry-von-sanket-goel","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
