| 摘要 |
A method of collecting and detecting microorganisms in a fluid, comprising the steps of treating a substrate with a polycationic electrolyte, such as poly-L-lysine or polyethyleneimine (PEI), causing microorganisms to be adhered to the substrate and scanning the substrate with a scanning laser in order to count or detect the microorganisms. Also claimed is a method of collecting and detecting microorganisms in a fluid comprising subjecting a sample of the fluid to dielectrophoresis and collecting the microorganisms onto a microelectrode, scanning the microelectrode using a scanning laser and determining the number of microorganisms present on the microelectrode. |
