The sudden emergence of novel coronavirus CoVID-19 in China during the end of last year and its outburst all around the globe thereafter have raised serious questions about their instant management and diagnostic measures as it is infecting humans around in an exponential manner. The implementation of nanotechnology could perhaps ingenerate the rising distress due to the spread of the disease as the conventional antiviral drugs just control the symptoms. Nanoparticles drug delivery systems are engineered technologies that use nanoparticles for targeted drug delivery and controlled release of therapeutic agents. Nanoparticles based approach can replace the treatment with a more promising one that could meet these challenges. Understanding molecular pathogenesis of CoVID-19 infection is very important to exploit the nanoparticles to fight against it. A lot of nanostructures have been developed with antiviral and antibacterial properties for a variety of drug delivery and biomedical applications. The need of the hour is to exploit nano research to develop effective diagnostics tools, drugs, vaccines to treat and prohibit infection. In this paper an attempt has been made to understand the role and potential of various nanoparticles to inhibit CoVID-19 infection and its toxicity effects.

Aim: To investigate the application of Scrotal Heat Stress (SHS) and Pulsed Unfocused Ultrasound (PuFUS) to explore Blood-Testis Barrier (BTB) permeability in adult mice. Background: The BTB provides a stable microenvironment and a unique immune barrier for spermatogenesis. Meanwhile, it blocks macromolecular substances access, including therapeutic agents and antibodies, thereby it decreases the therapeutic or immunocontraception effects. Objectives: To determine the viability of these physical approaches in delivering macromolecular substances into seminiferous tubules. Material & Methods: Mice were subjected to receive single SHS intervention at 39°C, 41°C, or 43°C for 30 min. Whereas, mice received the PuFUS intervention at 1.75w/cm2, 1.25w/cm2, and 2.5w/cm2 for 2 min, 5 min, and 10 min, respectively. The Biotin and macromolecular substances (IgG, IgM, and exosomes) were separately injected into the testicular interstitium at different times following SHS or PuFUS interventions, to observe their penetration through BTB into seminiferous tubules. Results: As detected by Biotin tracer, the BTB opening started from day-2 following the SHS and lasted for more than three days, whereas the BTB opening started from 1.5h following PuFUS and lasted up to 24h. Apparent penetration of IgG, IgM, and exosomes into seminiferous tubules was observed after five days of the SHS at 43°C, but none at 39°C, or any conditions tested with PuFUS. Conclusion: The current results indicate that SHS at 43°C comparatively has the potential for delivering macromolecular substances into seminiferous tubules, whereas the PuFUS could be a novel, quick, and mild approach to open the BTB. These strategies might be useful for targeted drug delivery into testicular seminiferous tubules. However, further studies are warranted to validate our findings.

Abstract Annotation. Nanopowders of aluminum oxide silicon oxide and iron oxide with silver coating were produces by the radiation-chemical method. The dimensions of the nanoparticles were 50 to 80 nm, and the area can be changed from 2-3%, up to 40%. Was carried out the validation of antibacterial properties against E.coli and staphylococcus. Were estimated photocatalytic properties of nanopowders, which showed applications perspective as a photocatalytic agent. Cytotoxic properties were also investigated, which showed the relevance of the use of some the obtained composites for targeted drug delivery.

Magnetic iron oxide nanoparticles (MNPs) have been developed and applied for a broad range of biomedical applications, such as diagnostic imaging, magnetic fluid hyperthermia, targeted drug delivery, gene therapy and tissue repair. As one key element, reproducible synthesis routes of MNPs are capable of controlling and adjusting structure, size, shape and magnetic properties are mandatory. In this review, we discuss advanced methods for engineering and utilizing MNPs, such as continuous synthesis approaches using microtechnologies and the biosynthesis of magnetosomes, biotechnological synthesized iron oxide nanoparticles from bacteria. We compare the technologies and resulting MNPs with conventional synthetic routes. Prominent biomedical applications of the MNPs such as diagnostic imaging, magnetic fluid hyperthermia, targeted drug delivery and magnetic actuation in micro/nanorobots will be presented.
