Abstract

Real-time enrichment and detection of airborne bacteria is an emerging and rapidly evolving field of research because of the ability of these pathogens to cause infectious diseases. In this paper, we introduce gold nanoparticles embedded microfluidic chips which is suitable for enrichment bacteria and extracting DNAs from airborne bacteria. Using herringbone microstructures, introduced bacteria are captured onto the inner surfaces of channels. Subsequently, 532nm wavelength of laser is irradiated to gold nanoparticle-embedded chips for 2 minutes. Then, we can identify that the enrichment efficiency is almost 95% and the killing rate of bacteria is up to 88%.
