Teams from Japan, Pakistan and Vietnam develop bioactive mix Viroblock

A team of researchers from Japan, Pakistan and Vietnam have developed a mixture of aliphatic lipid chains and certain cyclodextrins. It is produced by enzymatic conversion from starch and can reduce the amount of lipids in the antiviral wall. As a result of silver penetration, viral replication is inhibited and infectious pathogens are killed.

The effectiveness of this bioactive chemical, called Viroblock (VB), was demonstrated by a four-to-counter reduction in H1N1, H5N1, coronavirus, and other virus-related respiratory illnesses. Logarithmic reduction is a measure of how drastically the decontamination process reduces the concentration of pollutants.

Face mask tests showed a 4-log reduction in treated and untreated specimens, with long-term effects on a variety of products such as drapes, medical garments, masks, and air filters.

We investigated the surface structure of PAN electrospinning nanofibers supplied with four different concentrations of VB. The size distribution of the nanofibers was determined to be 373.40 nm for pure PAN electrospinning nanofibers. Researchers reported in the journal that PAN electrospinning nanofibers with 0.5 percent VB had an average size of 366.55 nm and a standard deviation of 49.55 nm. Applied science..

Hydrophilicity was confirmed by the water content and water contact angle, which are important properties that determine the contamination sensitivity of the membrane.

The results showed that the integration of VB into PAN nanofibers did not affect the water content values. All specimens had a water contact angle of less than 90 degrees and all films produced were declared hydrophilic.

The results showed that as the proportion of VB in VB / PAN nanofibers increased, the mass residual rate of VB / PAN nanofibers increased. The amount of Ag present in VB justified the pattern, as Ag was thermally stable over this temperature range. The increase in VB concentration also resulted in a decrease in breathability.

The analysis was used to investigate the cytotoxicity of PAN nanostructures and VB / PAN nanofibers in biomedical applications. Cells have been shown to be more robust with greater absorption capacity of deposited formazan as VB levels increase. The vitality of all nanofibers improves over time, indicating that the framework is suitable for metabolic activity and cell proliferation.

After the wall was destroyed, silver infiltrated the bacteria and bound to sulfur-containing enzymes, causing reduced function and oxidative damage to DNA.

In short, this new study used an electrospinning process to effectively produce VB / PAN nanofibers with antiviral properties.
