METHOD FOR MEASURING THE AMOUNT OF BACTERIA

摘要

PURPOSE: A method for measuring the amount of bacteria using a nano biosensor is provided to quickly measure the number of bacteria with high sensitivity. CONSTITUTION: A method for measuring the number of bacteria comprises: a step of isolating bacteria group in a sample; a step of inputting antibody-fixed nano biosensor to the bacteria group to label only bacteria; a step of removing unlabeled bacteria; a step of measuring the number of bacteria in the sample using fluorescence intensity generated in the nano biosensor. The step of isolating bacteria group comprises: a step of inputting magnetic particles having antibodies on the surface; and a step of separating bacteria using a magnet.
