Scientists from the ICN2 Nanobioelectronics and Biosensors Group led by ICREA Prof. Arben Merkoçi have carried out a study to enhance the sensitivity of lateral flow tests. They included cellulose nanofibers in the test area, producing an average increase of 36.6 percent of the colorimetric signal on positive tests. The proposed modification can be easily applied to any kind of lateral flow strip, enabling its use in point-of-care applications.
