This study involves the formulation of cobalt nanoparticles by means of ethanolic Azadirachta indica (neem) extract (CoNP@N). Later, the formulated buildup was incorporated into cotton fabric in order to mitigate antifungal infection. Optimization of the formulation was carried out by considering the effect of plant concentration, temperature, and revolutions per minute (rpm) used, through design of the experiment (DOE), response surface methodology (RSM), and ANOVA of the synthetic procedure. Hence, graph was potted with the aid of effecting parameters and the related factors (size of particle and zeta potential). Further characterization of nanoparticles was performed through scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Attenuated total reflection–Fourier transform infrared (ATR-FTIR) was considered for the detection of functional groups. The structural property of CoNP@N was calculated with the aid of powder X-ray diffraction (PXRD). The surface property was measured with the use of a surface area analyzer (SAA). The values of Inhibition concentration (IC50) and zone of inhibition (ZOI), were calculated, so as to determine the antifungal property against both the strains (Candida albicans, MTCC 227and Aspergillus niger, MTCC 8652). The further nano-coated cloth was subjected to a durability test, and hence the cloth was washed (through the purpose of time 0; 10; 25; and 50 washing cycles), and then its anti-fungal operation to a couple of strains was retained. Primarily, 51 μg/ml of cobalt nanoparticles incorporated on the cloth was retained but after 50 washing cycles in 500 ml of purified water, the cloth showed more efficiency contrary to C. albicans than towards A. niger. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2023.
Protective face mask: an effective weapon against SARS-CoV-2 with controlled environmental pollution
(Springer, 2024) Shovan Ghosh; Vivek Dave; Prashansa Sharma; Akash Patel; Arindam Kuila
Masks are face coverings that give protection from infectious agents, airborne pathogens, bacteria, viruses, surgical fog, dust, and other chemical hazards by acting as a barrier between the wearer and the environment. In the COVID-19 pandemic, this major personal protective equipment’s became essential part of our daily life. The aim of this review is to analyze and discuss the different types of masks with their pros and cons, manufacturing procedures, evaluation criteria, and application with some of the sterilization process for reuse and smart mask. The review used a thorough examination of the literature to analyze the preventive effects of surgical, N95, smart mask, and potential environmental damage from those masks. Several studies and evidence were also examined to understand the efficiency of different mask on different environment. N95 respirators are capable of filtering out non-oil-based 95% air-born particles, and surgical masks act as a protective barrier between the wearer and the environment. The application of spoon bond and melt blown techniques in the fabrication process of those masks improves their protective nature and makes them lightweight and comfortable. But the high demand and low supply forced users to reuse and extend their use after sterilizations, even though those masks are recommended to be used once. Universal masking in the SARS-COV-2 pandemic increased the chance of environmental pollution, so the application of smart masks became essential because of their high protection power and self-sterilizing and reusing capabilities.
