ure ▁for ▁ret inal ▁dise ases ▁including ▁total ▁blind ness . ▁So ▁far , ▁only ▁partial ▁vision ▁repair ▁has ▁been ▁reported . ▁ ▁Micro fl uid ic ▁devices ▁ ▁Due ▁to ▁some ▁of ▁the ▁problems ▁with ▁F AC S ▁and ▁MAC S ▁devices , ▁micro fl uid ic ▁cell ▁sorting ▁devices ▁have ▁been ▁recently ▁investig ated ▁and ▁research ▁is ▁being ▁conducted ▁in ▁an ▁attempt ▁to ▁commercial ize ▁these ▁devices ▁for ▁clin ical ▁use ▁and ▁point ▁of ▁care ▁applications . ▁Micro fl uid ic ▁devices ▁overcome ▁some ▁of ▁the ▁limitations ▁of ▁other ▁methods ▁by ▁providing ▁a ▁compar able ▁target ▁cell ▁pur ity ▁of ▁around ▁ 9 9 % ▁in ▁some ▁cases ▁and ▁high ▁cell ▁outputs ▁of ▁around ▁ 4 8 , 0 0 0 ▁cells / second . ▁Other ▁benefits ▁include ▁reduced ▁risk ▁of ▁comprom ising ▁the ▁cell ▁vi ability ▁due ▁to ▁lower ing ▁the ▁need ▁for ▁high ▁pressure ▁she ath ▁flow ▁to ▁focus ▁the ▁cells , ▁multi - path way ▁sorting ▁ability ▁with ▁some ▁devices ▁allowing ▁ 5 ▁different ▁out lets ▁for ▁separation , ▁decre ased ▁cost ▁of ▁micro fl uid ic ▁channels ▁due ▁to ▁cheap ▁manufact uring ▁methods , ▁lower ▁power ▁consumption , ▁and ▁smaller ▁size ▁foot print ▁with ▁some ▁devices ▁being ▁the ▁size ▁of ▁a ▁credit ▁card . ▁ ▁The ▁development ▁of ▁small ▁micro ▁channels ▁made ▁with ▁soft ▁l ith ography ▁techniques ▁that ▁util ize ▁materials ▁such ▁as ▁pol yd im eth yl sil ox ane ▁( PD MS ) ▁and ▁epo x ies ▁offers ▁a ▁unique ▁way ▁to ▁sort ▁cells
