According to medical knowledge, SARS-CoV-2 virus behind COVID-19 is only one of the many viruses in the coronavirus family. In fact, many of these viruses are presents in animal populations and have the potential to transmit to the human population, in the way SARS-CoV-2 did.
Meanwhile, a team of researchers at the David Baltimore Professor of Biology and Bioengineering are engaged to develop vaccines for a host of related coronaviruses, with the objective to prevent pandemics in the future.
In fact, a team at Caltech have designed a protein-based subunit of 60 nanoparticles. The subunit is attached with up to eight different types of coronavirus. For experimental purpose, when the nanoparticle is injected into mice, it induces production of antibodies that react against different coronaviruses. This includes similar viruses that were not included on the nanoparticle.
The findings of the study is published in a paper in Science.
Platform for Nanoparticle vaccine developed by University of Oxford
Termed mosaic nanoparticle, the vaccine platform was earlier initially developed by collaborators at the University of Oxford. Structurally, the nanoparticle is in the shape of a cage made up of 60 identical proteins. And, each nanoparticle has a small protein tag that functions like a piece of Velcro.
To establish the efficacy of nanoparticles, the team used fragments of spike proteins of a few strain of coronaviruses, and engineered each coronavirus to have a protein tag that would attach to the ones on the cage. The mixing of viral pieces with the nanoparticle cage structure led to each virus tag to attach to a tag on the cage, making a nanoparticle that represents different strains of coronavirus on the surface.
Teflon is the trade name of polytetrafluoroethylene, or PTFE, by DuPont is a high-end thermoplastics that has been popularly used in food grade gasket. The rise in food industry applications is one of the key trends in the Teflon food grade market. Teflon is well-known for its non-stickiness and hence have been commercialized in food grade compliancy. A wide range of cooking appliances incorporate non-stick Teflon coating. These have gathered immense steam among health-conscious consumers. The chemical inertness over a wide temperature range has attracted the attention of food packaging industries over the years. Some of the other benefits Teflon coating offers are heat and water resistance. They have also score high on aesthetics of prospective customers. This is a key driver for opportunity in the Teflon food grade market.

Rising use of FDA-approved virgin PTFE in the food and beverages industry has broadened the revenue potential for industry players in the market. The incorporation of new fillers has further enhanced the properties of Teflon food grade.
North America and Asia Have Been Lucrative Markets
A thriving non-stick cookware market in Asia Pacific has been hotbed of opportunities for the value chain in the Teflon food grade market. North America is one of the key consumers of Teflon food grade. Apart from food applications, the versatility of PTFE has also reinforced the opportunity for manufacturers and chemical companies in the market.
However, in recent years Teflon has come under scanner due to its supposed carcinogenic nature. But the results have not been of any significant concern, and key consumer markets have continued to use Teflon-coated cookware. A case in point is the consumer base in the U.S. A growing body of research hasn’t been able to arrive at any definitive results about the chemical. On the other hand, the sheen of the Teflon food grade continues to elevate, seeing new markets and new consumers, and, hence new revenue streams.

Biologic surgical patches are expected to have a larger market share in comparison to synthetic surgical patches as it offers more benefits such as reduced risk of infections. Cardiovascular surgery is expected to have the largest revenue share in the application segment and will continue to dominate the market during the forecast period as well. This is due to rising cardiovascular diseases often leading to surgeries. According to CDC’s 2020 estimates, one person dies in every 36 seconds in the U.S from cardiovascular disease. The hospitals will contribute maximum revenue in the surgical patches market followed by ambulatory care services. The rise in prevalence of cardiovascular diseases majorly, in both developed and developing countries which is leading to a rise in the number of cardiovascular surgeries is expected to drive the growth of the market. In addition, the increase in geriatric population is also expected to drive the growth of the surgical patches market.

Geographically, the Surgical Patches Market is segmented into seven regions viz. Europe, South Asia, East Asia, Oceania, Latin America, North America and Middle East & Africa. The North America is expected to hold the largest market share in the global surgical patches market with U.S. being the major contributor of revenue. The developed healthcare infrastructure and the rising prevalence of cardiovascular diseases in North America is expected to boost the growth of the surgical patches market.
South Asia and East Asia is anticipated to experience maximum growth in the surgical patches market. This is attributed towards the rise in geriatric population in this region. Additionally, the increasing awareness regarding healthcare procedures and rising government initiatives is also expected to drive the growth of the market in this region.

Increased Prevalence Air Pollution to Widen Scope of Growth of the Market
Several established companies from various other industries as well as new entrants have made foray into the face mask market. A case in point is Adidas introducing reusable face mask, Face Cover. This face mask by Adidas is made using breathable recycled material and is sold on different e-commerce sites, such as Myntra, Adidas, Flipkart, and Amazon.com. Such innovations and developments are likely to support growth of the global reusable face mask market in the near future.
Increased entry of several start-ups, new entrants, and local manufacturers in the global reusable face mask market has resulted in environment-friendly and sustainable options. For instance, an apparel company, Onzie makes use of breathable, up-cycled bamboo fabric to produce reusable masks. Such innovative steps taken by various companies are likely to work in favor of the global reusable face mask market in the years to come.
