Not only pathogenic bacteria, but also viruses, prions, fungi, their spores, and endotoxins generated by bacteria, are not responsible for spreading hospitals-acquired infections (HAIs) or nosocomial infections. Traditional approaches and standardization used in ventilation systems installed in hospitals involve two filter beds. As the pathogens and some of their byproducts go on entrapping with the regular usage within the filter beds, the filters need to be replaced after a specific period.
Now, scientists at Rice University have designed a graphene-based fabric that entraps a range of pathogens and eventually destroys or deactivates by applying extensive heat. It indicates that the graphene filter would be significantly durable than the traditional filter beds.
In some earlier research, Rice University built the innovative laser-induced graphene (LIG) fabric, which the researchers used as an efficient filter for ventilation systems. It is a conductive porous material formed by heating the unadulterated and atomically thin carbon sheets using an industrial laser cutter. By conducting sufficient voltage of electricity through it for a limited period, the temperature of LIG surpasses 350°C. At such extreme temperatures, along with bacteria, their endotoxins, spores, fungi, prions, and other hazardous airborne particles are deactivated. The heat treatment should be applied once in a while to destroy whatever gets adhered to the fabric. The heating and cooling process is quite quick and needs little operational energy.
On a related note, Camfil, a globally trusted company dedicated to manufacturing and developing clean air solutions, is eager to publicize the news revealing the efficiency of its molecular filtration systems set up in food processing and packaging units. Camfil’s concept behind designing molecular filtration evades the usage of sterilants, such as HP sterilants and PAA, in food processing units owing to the safety concerns.
Mark Davidson, Camfil’s Food and Beverage Segment Manager, told that commonly used sterilants in the aseptic filling are hydrogen peroxide and peracetic acid. The residues of such sterilants, if not addressed properly, could pose health risks to employees working in the facility and even delay the production time.
