Abstract

Achieving selective and sensitive carbohydrate–protein interactions (CPIs) using nanotechnology is an intriguing area of research. Here we demonstrate that the different shapes of gold nanoparticles (AuNPs) functionalized with monosaccharides tune the bacterial aggregations. The mechanism of aggregation revealed that the large number of surface interactions of rod shaped mannose-AuNPs with E. coli ORN 178 compared with spherical and star-shaped AuNPs exhibited higher avidity and sensitivity. Moreover, such sensitive binding can be used for effective inhibition of bacterial infection of cells. [ABSTRACT FROM AUTHOR]

Abstract

We describe here the sugar functionalized β-cyclodextrin–ferrocene glass slides as fully reversible bacterial biosensors under the influence of external adamantane carboxylic acid. The prototype d-mannose –E. coli ORN 178 and l-fucose –P. aeruginosa interactions serve as a model to illustrate the new approach. [ABSTRACT FROM AUTHOR]
