The invention discloses a laser rapid detection and sterilization integrated device and method for viruses and bacteria. The device comprises a laser, a light beam scanning element, a sample collection element, a micro-fluidic chip and a Raman spectrum detection platform. The laser comprises a laser generation source, a light splitting element and a frequency doubling element. A light beam emittedby the laser generation source forms two split light beams through the light splitting element, and one beam forms an excitation light source of the Raman spectrum detection platform. A sample is adsorbed and blocked by the nanotube assembly of the micro-fluidic chip according to the size from large to small to form a bacterial virus area classified according to the size; the excitation light source irradiates each bacterial virus area to obtain microbial identification information; and the other beam forms an ultraviolet laser beam through the frequency doubling element, and the ultravioletlaser beam flows to the be
