Rapid measurement of waterborne bacterial viability based on difunctional gold nanoprobe

Abstract

A colorimetric method is proposed to measure waterborne bacterial viability by using a difunctional gold nanoprobe that can generate color signals while recognizing bacterial suspensions of different viabilities.

Development of a Colorimetric Urease Test Based on Au NPS Capped with Anthocyanin for the Rapid Detection of Helicobacter pylori through Multiple Readouts

“…Up to date, gold nanoparticles (Au NPs) have been in use for a wide range of biomedical applications like drug delivery, disease treatment, optical imaging and catalysis owing to their physical and chemical properties. [1][2][3][4][5][6][7][8][9][10][11][12] In addition to that, Au NPs have been heavily incorporated to various sensing platform to colorimetrically detect a wide variety of targets including metal/nonmetals ions, [13][14][15][16] organic or biomolecules [17][18][19] and even virus, bacteria and also cancer cells [20][21][22][23][24][25][26] due its unique surface plasmon resonance (SPR) property. For instance, while the dispersed spherical Au NPs in solution gives wine-red color, when they are in close proximity each other, they are in tendency to aggregation and induce blue-purple color.…”
