In the presence of harmful pathogens, receptor coated silver nanoparticles (AgNPs) preferentially bind to the bacterial surface and urease catalytically elevates the pH of the solution, which is sensed by a pH responsive chromogenic dye. The assay demarcates bacterial contamination levels up to 102 cells mL-1 in a field-friendly method. date: 2019-04-18 date_type: published publication: Chemical communications (Cambridge, England) volume: 55 number: 33 publisher: Royal Society of Chemistry pagerange: 4765-4768 refereed: TRUE issn: 1364-548X official_url: https://pubs.rsc.org/en/content/articlelanding/2019/CC/C9CC00225A#!divAbstract citation: Singh, Pargat and Kakkar, Saloni and Bharti, . and Kumar, Rajesh and Bhalla, Vijayender (2019) Rapid and sensitive colorimetric detection of pathogens based on silver-urease interactions.
