21st International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2017 1145-1146 2020年
Here we present a new approach to rapid formation of collagen gel tubes using microfluidic devices made of phosphate particle-embedding PDMS (PP-PDMS). An acidic solution of collagen, introduced into the PP-PDMS channel, was rapidly transformed in...
