Colorimetric Detection of Bacteria Using Au Nanoparticles

Colorimetric detection, a technique that observes changes in colour as a signal, has been employed in the identification of bacterial presence using gold nanoparticles (Au-NPs). Au-NPs exhibit unique optical properties, changing their colour in response to bacterial interactions. This straightforwar...

description Colorimetric detection, a technique that observes changes in colour as a signal, has been employed in the identification of bacterial presence using gold nanoparticles (Au-NPs). Au-NPs exhibit unique optical properties, changing their colour in response to bacterial interactions. This straightforward and rapid method offers potential for early diagnosis and monitoring of bacterial infections. The sensitivity and specificity of Au-NPs provide a promising tool for the next-generation point-of-care diagnostics, streamlining bacterial detection without the need for complex instrumentation.
