Laser rapid detection and sterilization integrated device and method for viruses and bacteria

Abstract

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 beam scanning element. According to the invention, a closed-loop process of rapid detection, disinfection and disinfection and disinfection effect recheck of bacterial virusesis realized, the effectiveness of disinfection and disinfection is ensured, the disinfection and disinfection efficiency is high, the disinfection and disinfection are rapid and targeted, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of sterilization and disinfection devices, and more specifically relates to an integrated device and method for laser rapid detection and disinfection of viruses and bacteria. Background technique [0002] In response to the food environment safety and public health issues that people are concerned about, the poor food environment and poor public health cause the growth and infection of bacteria and viruses, and the diseases and epidemics caused have a profound impact on my country's society and economy. , equipment and other deficiencies. There is an urgent need for a rapid detection and disinfecting integrated technology to carry out scientific disease prevention and build a food safety system and public health safety system under the new situation. [0003] In modern society, the food environment problems in supermarkets, vegetable markets and other places are closely related to the health and safety prob...

AI Technical Summary

Problems solved by technology

Currently, the workload of health and safety inspections in public places is heavy, and there is a lack of detection methods for bacteria and viruses. The existing detection technology generally adopts the "offline" detection mode of on-site sampling, laboratory extraction and specific detection, which has poor real-time performance and is not sensitive to unknown bacteria. The specific detection of viruses is difficult; and the existing bacteria and virus disinfecting in public places cannot be targeted and blind; the disinfecting methods are inefficient and mostly have harmful residues, which is unsafe; valid, uncertain

[0004] In the case of a large-scale epidemic situation, when it is necessary to screen personnel, the complex screening process increases the burden on medical staff and the risk of infection, and a simple and fast automatic detection method is required; the existing bacterial virus detection needs to understand the DNA / RNA characteristics of the corresponding bacterial virus , the RT-PCR detection of the corresponding bacterial virus can be carried out, and the prevention of new bacterial viruses cannot be achieved
