A Printable OECT for Simple Integration in Nitrocellulose-Based Assays. [PDF]

ACS Sens
Paper-based biosensors hold significant promise for point-of-care (POC) diagnostic applications. Among these, lateral flow assays (LFAs) are particularly appealing due to their ease of use, portability, and low cost. However, their limited sensi-tivity and qualitative output set drawbacks on their reliability and widespread application.
