The gold standard method for identifying Ebola virus in blood samples requires that the blood sample be sealed in a refrigerated container and sent to a specialist laboratory away from the patient's home. Such laboratories use a reverse transcriptase polymerase chain reaction (RT-PCR) method to check for viruses. After the virus is not detected in the blood, the virus may still be contained in the body fluid, and the lengthy testing process may delay the detection, treatment and real-time monitoring of the viral load.
Scientists and their counterparts at the Korean Institute of Science and Technology (KIST, Saarbrücken, Germany) designed an instrument that can perform four-way RT-PCR, including two controls and two patient blood samples. Traditional tests take hours to more than one day to get results. The new assay process takes only 30 minutes to complete. The required amount of blood is 100 nanoliters and may only be collected from your fingertips.
Experiments have shown that the device can perform four-way PCR simultaneously, including a positive control, Ebola RNA and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) RNA, and a negative control. The device successfully detected Ebola RNA (RNA). The test not only diagnoses the disease, but also generates information on how many copies of the RNA are contained in each sample. Experts say the tool is also expected to help medical workers track viral load in semen, milk and eye fluids after the patient recovers.
Relative quantification was obtained by comparing the critical cycle numbers (CT) of the two samples. The entire process includes reverse transcription, PCR amplification, and melting curve analysis (MCA), which can be completed in less than 37 minutes. The next step is to integrate the sample preparation device to form an integrated system. After inputting the sample, the results are directly obtained for the diagnosis of infectious diseases by the bedside.

Dynamic disinfection is a process of disinfection and cleaning of air and surfaces in indoor Spaces. A
new method of safe disinfection that does not cause harm or interference to people and the environment on
site.The charged particles and active oxygen components produced by the low-temperature plasma in the
equipment play a major role in the process of killing bacteria and viruses, and have the effect of
broad-spectrum sterilization. It can not only inactivate aerosol plankton in the air and bacteria
and viruses on the surface of object but also effectively decompose formaldehyde and volatile organic
compounds, degrade all kinds of bad smell and purify it Air environment.A small amount of high purity
zone.
Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to decoration pollution that can absorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc. , bacteria, allergens, etc.), household appliances that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and building.
There are many different technologies and media in air purifiers that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Carbon core filter technology, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are used at the same time.
