Branching and size of CTAB-coated gold nanostars control the colorimetric detection of bacteria
Verma, Mohit S.; Chen, Paul Z.; Jones, Lyndon W.; Gu, Frank X. (Royal Society of Chemistry, 2014)Rapid detection of pathogenic bacteria is challenging because conventional methods require long incubation times. Nanoparticles have the potential to detect pathogens before they can cause an infection. Gold nanostars have ... -
Controlling “chemical nose” biosensor characteristics by modulating gold nanoparticle shape and concentration
Verma, Mohit S.; Chen, Paul Z.; Jones, Lyndon W.; Gu, Frank X. (Elsevier, 2015-09)Conventional lock-and-key biosensors often only detect a single pathogen because they incorporate biomolecules with high specificity. “Chemical nose” biosensors are overcoming this limitation and identifying multiple ... -
Towards point-of-care detection of polymicrobial infections: Rapid colorimetric response using a portable spectrophotometer
Verma, Mohit S.; Tsuji, Jackson M.; Hall, Brad; Chen, Paul Z.; Forrest, James; Jones, Lyndon W.; Gu, Frank X. (Elsevier, 2016-09)Infectious diseases spread rapidly because current diagnostic methods are slow, expensive, and require technical expertise. Biosensors have recently been used as devices that can be deployed at the point-of-care for rapid ...
