The main idea behind viral processing is to stop the viruses in a given sample from contaminating the desired product. The two most widely used methods of viral processing are viral removal and viral inactivation. The former is a method in which all viruses are simply removed from the sample completely. The latter method is one in which the viruses may remain in the final product, but in a non-infective form. These techniques are used widely in the food and blood plasma industries, as those products can be harmed by the presence of viral particles. Some of the more common viruses removed by these methods are the HIV-1 and HIV-2 viruses; hepatitis A, B, and C; and parvoviruses. The methods used in the plasma industry have been summarized (Horowitz B., Minor P., Morgenthaler J. J., Burnouf T., McIntosh R., Padilla A., Thorpe R. and van Aken W. G. Who Expert Committee on Biological Standardization. World Health Organ Tech Rep Ser. 924: 1-232, 2004.) In some cases, however, it is the virus itself that is the desired product, as is often the case with the HIV. In many cases, researchers may be trying to extract the viruses from the blood for study, not specifically for blood purification. It is also common to use these types of techniques to remove particles produced as a result of viral infection.

Caulis peristrophis for aquaculture tail water virus enrichment and disinfection and preparation method thereof
ActiveCN120288905BSpecific water treatment objectivesWaste water treatment from animal husbandryNanocarriersCyclic diguanylic acid
This invention discloses a periclump biocarrier for virus enrichment and elimination in aquaculture wastewater and its preparation method. The periclump biocarrier has a core-shell structure, with a core consisting of a signal layer loaded with catalytic particles, and an outer shell consisting of a support layer. The signal layer is a gel dispersed with cyclic diguanosine monophosphate, the catalytic particles are nanocarriers loaded with sodium percarbonate and potassium ferrocyanide, and the support layer is a porous polymer. This invention optimizes the virus enrichment capacity of biofilms and enhances in-situ elimination efficiency by integrating signal molecule regulation and free radical synergistic inactivation mechanisms. This periclump biocarrier not only improves the targeting and response speed of virus treatment but also overcomes the environmental risks and cost bottlenecks of traditional methods, providing an innovative solution for the safe management of aquaculture water bodies, and can achieve a virus inactivation rate of ≥99.9%.

Virus processing method, device and system and storage medium
The invention discloses a virus processing method, device and system and a storage medium, and the method comprises the steps: comparing vehicle software mirror image data with a virus template library when the vehicle software mirror image data is received; when the comparison result is inconsistent, judging whether viruses exist in the vehicle software mirror image data or not; when the virus exists, an active confrontation mode is adopted to attack a source server of the virus so as to block a virus transmission source; when the virus is an unknown virus, acquiring feature information of the unknown virus; and updating a virus template library according to the feature information of the unknown virus. According to the scheme provided by the invention, when the virus is found, an active confrontation mode is adopted to attack the virus source server, so that the propagation path of the virus is effectively blocked, and the large-scale diffusion of the virus is prevented, thereby reducing the harm range of the virus and improving the network security.
