Abstract

We have developed a novel immunoassay device which has a long and thin wall structure inside a microchannel, hence the name 'immuno-wall device'. Unreacted antigens and antibodies were completely removed by just immersing the device in a washing buffer for 1 minute. The long structure also allowed us to analyze fluorescence intensity by using inexpensive desktop fluorescence reader ($6,000) instead of expensive fluorescence microscopes. By using the immuno-wall devices and the fluorescence reader, the high-sensitivity C-reactive protein assays were performed with sample-in-answer-out in 15 minutes.
