Astrea Bioseparations Introduces Nereus LentiHERO, a Fit-for-purpose Solution for Lentiviral Vector Purification

“We believe that AstreAdept will be a game-changer,” explained Astrea Bioseparations’ CEO Terry Pizzie. “Our approach was to rapidly develop and incorporate this material into the Nereus LentiHERO, a simple, fit-for-purpose device that radically transforms how lentivirus can be purified [in terms of speed, recovery, and efficiency].

At Pack Expo, Schreiner MediPharm to Debut Functional Labels Designed from More Sustainable Materials

Schreiner MediPharm advises he new label concepts are based on existing items in Schreiner MediPharm’s roster of functional labeling solutions.

New test results demonstrate Saniconcentrate™, an additive technology patented by Parx Materials, reduces Covid-19 virus on surfaces by up to 99 percent in 24 hours.

Unlike other antimicrobial options, it achieves this without biocides, leaching, or harmful side effects, creating a breakthrough option for applications like touch surfaces in public areas, medical devices, or food contact applications. This proves Saniconcentrate™ will be a strong and safe tool in preventing the spread of viruses in the future.

With Saniconcentrate™, Parx Materials has created a way to make plastic intrinsically resistant to bacteria and viruses. The additive is homogenously incorporated into plastics to create an ’immune system’ inherent to the material.

Antimicrobial technologies have historically used biocides, such as silver or copper, to destroy microorganisms. While this method may effectively destroy bacteria and viruses, it can lead to toxic substances leaching out of the material, contaminating the products or surfaces it is trying to protect, as well as contaminating the environment and making recycling a more challenging task. In addition to relying on finite resources to work, bacteria and viruses tend to become resistant to biocides over time, reducing the biocides’ efficacy. Making bacteria viruses stronger so they become more difficult to battle and cause a bigger threat in the future.

Typically, bacteria and viruses attach to surfaces in order to sustain themselves over a long period of time. Inspired by the defense mechanisms of the human body, the technology of Parx Materials works by mimicking the physical characteristics of the human skin.

Saniconcentrate™ uses a trace element abundantly found in the body to prevent bacteria and viruses from adhering to surfaces, causing them to run through their usual lifecycle and die within hours. This ecological approach of dealing with germs can be seen as a natural way to keep bacteria and viruses at bay, instead of just killing them and inducing resistance.

As Saniconcentrate™ uses materials already found in the human body, it is biocompatible, safe and its applications are limitless. The technology is currently in use in major supermarkets and has shown outstanding results in medical trials.

A new study, carried out by an authorized laboratory, identifies the development of the amount of Covid-19 virus on plastic surfaces made with the Saniconcentrate™ additive. The test was carried out in accordance with ISO 21702:2019 “measurement of antiviral activity on plastics and other non-porous surfaces”. After 24 hours, the treated sample saw a 99 percent reduction in the virus.

A second test on a different material made with Saniconcentrate™, found a 53.23 percent reduction in Covid-19 virus after just six hours and a 93.24 percent reduction after 24 hours. This proves definitively that Saniconcentrate™ protects surfaces against coronavirus and therefore its spread. Here, Covid-19 and coronavirus refer to the SARS-CoV-2 virus; the tests were carried out using the COV2019 Italy/INMI1 strain.

Michal van der Jagt“Today’s struggles against the Covid-19 pandemic and antibiotic-resistant superbugs show that innovation is needed when it comes to antimicrobial materials,” commented Michaël van der Jagt, CEO of Parx Materials. “The test results showing a 99 percent reduction in coronavirus on Saniconcentrate™ treated surfaces confirms its ability to help us return to normal life using a safe and ecological approach.”

Parx Materials is currently looking for investment to further accelerate its scale-up.
