Abstract
The present invention relates, in general terms, to nanoparticle solutions, kits, devices and methods of use thereof. The present invention is suitable for use in quantifying bacterial cells in a sample. The method of quantifying bacterial cells in a sample comprises passing the sample in a liquid form and an aqueous nanoparticle solution through a porous substrate such that the bacterial cells in the sample is trapped on the porous substrate and can be quantified by a colorimetric and/or fluorescence output emitted from the nanoparticle bound to the bacterial cells.
