Cellulose Paper Sensors Modified with Zwitterionic Poly(carboxybetaine) for Sensing and Detection in Complex Media

Poly(carboxybetaine) (PCB) functionalized cellulose paper was used as a paper-based microfluidic device. The results showed that the PCB modified paper sensor was able to achieve (a) more rapid and sensitive glucose detection from undiluted human serum compared to bare cellulose and (b) specific ant...

Zusammenfassung:Poly(carboxybetaine) (PCB) functionalized cellulose paper was used as a paper-based microfluidic device. The results showed that the PCB modified paper sensor was able to achieve (a) more rapid and sensitive glucose detection from undiluted human serum compared to bare cellulose and (b) specific antigen detection via covalently immobilized antibodies.
