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 ... -
Petroleomic analysis of the treatment of naphthenic organics in oil sands process-affected water with buoyant photocatalysts
Leshuk, Tim; Peru, Kerry M.; de Oliveira Livera, Diogo; Tripp, Austin; Bardo, Patrick; Headley, John V.; Gu, Frank (Elsevier, 2018-09-15)The persistence of toxicity associated with the soluble naphthenic organic compounds (NOCs) of oil sands process-affected water (OSPW) implies that a treatment solution may be necessary to enable safe return of this water ... -
Spiky gold shells on magnetic particles for DNA biosensors
Bedford, Erin E.; Boujday, Souhir; Pradier, Claire-Marie; Gu, Frank X. (Elsevier, 2018-05-15)Combined separation and detection of biomolecules has the potential to speed up and improve the sensitivity of disease detection, environmental testing, and biomolecular analysis. In this work, we synthesized magnetic ... -
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 ...
