On-chip filtration enrichment and ultrasensitive nanozyme-catalyzed colorimetric detection of Streptococcus pneumoniae in saliva samples.

Streptococcus pneumoniae (S. pneumoniae) is a major cause of respiratory infections, requiring rapid, sensitive, and accessible diagnostic tools for early intervention, especially in resource-limited settings. Herein, we developed a microfluidic immu…
