“…Such a charge distribution promotes spike corona stability and enhances virion attachment to receptors and membrane surfaces, which are mostly negatively charged (Adamczyk et al, 2021). Nonuniform charge distribution of the S protein also plays an important role in the non-specific electrostatic interactions of the virus with other charged macromolecules and macromolecular substrates in its environment (Javidpour et al, 2021; Arbeitman et al, 2021; Nie et al, 2021, 2022; Zhang et al, 2023).…”

Motivation: Charged amino acid residues on the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been shown to influence its binding to different cell surface receptors, its non-specific electrostatic interactions with the environment, and its structural stability and conformation. It is therefore important to obtain a good understanding of amino acid mutations that affect the total charge on the spike protein which have arisen across different SARS-CoV-2 lineages during the course of the virus' evolution. Results: We analyse the change in the number of ionizable amino acids and the corresponding total charge on the spike proteins of almost 2000 SARS-CoV-2 lineages that have emerged over the span of the pandemic. Our results show that the previously observed trend toward an increase in the positive charge on the spike protein of SARS-CoV-2 variants of concern has essentially stopped with the emergence of the early omicron variants. Furthermore, recently emerged lineages show a greater diversity in terms of their composition of ionizable amino acids. We also demonstrate that the patterns of change in the number of ionizable amino acids on the spike protein are characteristic of related lineages within the broader clade division of the SARS-CoV-2 phylogenetic tree. Due to the ubiquity of electrostatic interactions in the biological environment, our findings are relevant for a broad range of studies dealing with the structural stability of SARS-CoV-2 and its interactions with the environment. Availability: The data underlying the article are available in the online Supplementary Material.

The filtration of airborne particulate matter (PM) and aerosols utilizing nonwoven fibrous materials has received significant research concern due to the continuing global pandemics, especially the outbreak of coronavirus disease (COVID-19), and particularly for face masks as a measure of personal protection. Although spun-bond or melt-blown nonwoven fabrics are among the pioneer materials in the development of polymer microfiber-based face masks or air filters on a large scale, relatively new nonwoven manufacturing processes like electrospinning and solution blow spinning (SBS) are gaining momentum among manufacturers of filter membranes. The high filtration performance of nanofiber face masks is due to their high surface area to volume ratio which increases the interaction between the nanofiber and PM and improves the electrostatic charge distribution of electret filters, allowing enhanced capture capability based on electrostatic deposition. Moreover, the small diameter of nanofibrous filters improves the breathability of the face mask by providing the slip effect, which in turn reduces the pressure drop through the membrane. This paper provides a comprehensive review of contemporary advances in nanofiber face masks, detailing the working mechanism involved, reviewing recent experimental studies, and discussing improvements in filtration efficiency for three main nanofibrous air filtration strategies, including mechanical and electrostatic filtration and antimicrobial functionality. Furthermore, prospective research is introduced which considers the synergistic combination effects of the three filtration mechanisms in designing a multifunctional nanofiber structure that can efficiently capture a wide range of PM with higher filtration efficiency and lower drops in pressure. New trends in the antimicrobial activity of smart material-based nanofibrous membranes in the fight against infectious airborne agents are also described.
