Microfluidic device with optical sensor element based on sodiumborosilicate porous glasses for immune analysis

Results of studies on the implementation of a competitive immune analysis on at sodiumborosilicate porous glass SBS-MAP (490 nm average pore size, porosity 50 %) and in a microfluidic device with an integrated sensor element are discussed in the article. The opportunity of insulin detection is demonstrated in concentration range (2.9∙10 -7÷2.3∙10 -6) М at sensor element in sample volume 600 μl and in microfluidic device with sensor element in sample volume 40 μl.
