PEG-Modified Selenium Nanoparticles Dramatically Increases Antibody Binding Sites for Ultrasensitive Point-of-Care Detection of NT-proBNP.

Nanoparticle technology dramatically improves detection of heart failure signals in blood, potentially enabling faster diagnosis with simpler point-of-care tests.

This Analytical Chemistry paper describes PEG-modified selenium nanoparticles that dramatically increase antibody binding sites for ultrasensitive point-of-care detection of NT-proBNP, a key heart failure biomarker. The technology could improve rapid cardiac diagnostics in resource-limited settings.
