Recent advances in materials science: a reinforced approach toward challenges against COVID-19.

With the recent COVID-19 pandemic, medical professionals and scientists have encountered an unprecedented trouble to make the latest technological solutions to work. Despite of abundant tools available as well as initiated for diagnosis and treatment, researchers in the healthcare systems were in backfoot to provide concrete answers to the demanding challenge of SARS-CoV-2. It has incited global collaborative efforts in every field from economic, social, and political to dedicated science to confront the growing demand toward solution to this outbreak.

Improved antibacterial and cellular response of electrets and piezobioceramics.

The bacterial contamination in implants has been recognized as one of the key issues in orthopedics. In this article, a new technique of electrical polarization of various non-piezoelectric and piezoelectric biocompatible ceramics has been explored to develop antibacterial implants. Optimally processed hydroxyapatite (HA), BaTiO (BT), CaTiO (CT), NaKNbO (NKN) and their composites have been used as model biomaterials to verify the concept.

Electro-mechanical and Polarization-Induced Antibacterial Response of 45S5 Bioglass-Sodium Potassium Niobate Piezoelectric Ceramic Composites.

Besides the excellent osteoconductivity and biocompatibility of 45S5 bioglass (BG), poor mechanical and electrical properties as well as susceptibility toward bacterial adhesion limit its widespread clinical applications. In this context, the present study investigates the effect of addition of piezoelectric sodium potassium niobate (NaKNbO; NKN) on mechanical, dielectric, and antibacterial response of BG. BG-NKN ( = 0, 10, 20, and 30 vol%) composites were synthesized at 800 °C for 30 min.

Effect of pre-existing diseases on COVID-19 infection and role of new sensors and biomaterials for its detection and treatment.

The entire world is suffering from a new type of viral disease, occurred by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The present article briefly discussed the genome sequencing and interaction of host cells with SARS-CoV-2. The influence of pre-existing diseases such as diabetes, heart disease and age of the patients on COVID-19 infection is reviewed.

Combined effect of surface polarization and ZnO addition on antibacterial and cellular response of Hydroxyapatite-ZnO composites.

Bacterial infection is among the serious concerns in orthopaedic during/after surgery. Here, we demonstrate a novel technique to induce the antibacterial response in biomaterial substrates via surface polarization. In the present work, hydroxyapatite, HA-xZnO (x = 3.
