ABSTRACT
The coronavirus disease2019 (COVID-19) pandemic has highlighted the need for disposable biosensors that can detect viruses in infected patients quickly due to fast response and also at a low cost.The present review provides an overview of the applications of disposable biosensors based on metal nanoparticles in enzymatic and non-enzymatic sensors with special reference to glucose and H2O2, immunosensors as well as genosensors (DNA biosensors in which the recognized event consists of the hybridization reaction)for point-of-care diagnostics. The disposable biosensors for COVID19 have also been discussed.
ABSTRACT
'Campus Visit' is the most significant facet of college enrolment program. An in-person strolling 'campus-tour' is a tiresome task that is generally infeasible for the guests to explore all the amenities within a day due to distance, time constraints, or due to budgetary imperatives. With the innovative movements, the idea of the computerized visit goes under a bigger brolly of Virtual Reality and because of the ongoing COVID-19 pandemic, the demand for virtual exploration is on the rise. VR has an incredible potential to reimagine and reconstruct the reality with magnificent visualizations by allowing virtual access to objects and places that may be out of reach in the real world. Undoubtedly, 'Virtual-Tour' has become a celebrated methodology for cheap and cheerful voyaging. This perlustration perspicuously elucidates the impactful usage of VR in assorted fields and spotlights the use of VR in 'Campus-Tour'. Additionally, it focusses on featuring the quality and restrictions of prior proposed VR techniques and ultimately, drives out the supreme strategy that offers an immersive experience to the end-user. © 2020 IEEE.
