5 results about "Pathogen inactivation" patented technology

This invention provides a method for preparing pathological sections of plague-affected experimental animals. The method includes the following steps: S1: sample pretreatment and fixation; S2: pathogen inactivation verification; S3: tissue dehydration, clearing, and paraffin embedding; S4: paraffin embedding; S5: sectioning and spreading; S6: staining; S7: mounting. The method for preparing pathological sections of plague-affected experimental animals provided by this invention has the advantages of ensuring absolute safety in the preparation process of high-risk pathogen sections through strict biosafety zoning and double inactivation verification, and obtaining high-quality pathological sections.

To provide a pathogen inactivation device that can suppress ineffective consumption of a radical and is excellent in energy efficiency of treatment, and a pathogen inactivation method.SOLUTION: A pathogen inactivation device 1 comprises: a plasma generation chamber 10; a high-voltage electrode 20 and a ground electrode 30 that are arranged opposite to each other at a distance within the plasma generation chamber 10; a flow rate adjustment 40 that adjusts a flow rate of plasma source gas flowing into the plasma generation chamber 10; a pressure reducing pump 50 and a pressure adjustment 60 that adjust the pressure in the plasma generation chamber 10 to a predetermined pressure; and a high voltage power source 70 that generates discharge plasma P between the high voltage electrode 20 and the ground electrode 30.SELECTED DRAWING: Figure 1

A cell destruction method includes providing an anionic biomarker that comprises a magnetic material such as an iron or an iron compound. The anionic biomarker is introduced into an organism having pathogen cells with a negative charge. The anionic biomarkers are attracted to the negative charges of the pathogen and couple thereto. The anionic biomarker may also have a coupler portion that further aids in the anionic biomarker coupling to and being bound to the pathogen cell and / or cell wall. An electric field may be produced to cause the anionic biomarkers and / or the negative charges of the pathogen cell to polarize on or along the pathogen cell. A magnetic field is directed to cause the anionic biomarker, or magnetic material thereof to move and damage the cell. The magnetic field may be an alternating magnetic field that causes the magnetic material to oscillate and damage the cell wall.

An improved technology for inactivation of viruses, for example the SARS-COV-2 virus that is causing the Covid-19 pandemic, is described. The technology can include a device that includes a substrate coated in a polymer that is infused with a pathogen inactivating material. In various embodiments, at a given time, a portion of the pathogen inactivating material is exposed to the environment, and the device is configured to periodically or intermittently expose additional pathogen inactivating material to the environment. For example, the polymer can be ablative or sacrificial.
