Size-Selective Bubble-Array Acoustofluidic Separation Enables Colorimetric Detection of Salmonella.
Rapid and reliable detection of foodborne pathogens is essential for ensuring food safety. Here, we report an integrated acoustofluidic biosensing platform for quantitative detection of Salmonella that couples a vibrating bubble-array microchannel with nanozyme-based colorimetric readout. In this design, air bubbles ar...
