Summary
The rapid propagation of novel human coronavirus 2019 and its emergence as a pandemic raising morbidity calls for taking more appropriate measures for rapid improvement of present diagnostic techniques which are time‐consuming, labour‐intensive and non‐portable. In this scenario, biosensors can be considered as a means to outmatch customary techniques and deliver point‐of‐care diagnostics for many diseases in a much better way owing to their speed, cost‐effectiveness, accuracy, sensitivity and selectivity. Besides this, these biosensors have been aptly used to detect a wide spectrum of viruses thus facilitating timely delivery of correct therapy. The present review is an attempt to analyse such different kinds of biosensors that have been implemented for virus detection. Recently, the field of nanotechnology has given a great push to diagnostic techniques by the development of smart and miniaturised nanobiosensors which have enhanced the diagnostic procedure and taken it to a new level. The portability, hardiness and affordability of nanobiosensor make them an apt diagnostic agent for different kinds of viruses including SARS‐CoV‐2. The role of such novel nanobiosensors in the diagnosis of SARS‐CoV‐2 has also been addressed comprehensively in the present review. Along with this, the challenges and future position of developing such ultrasensitive nanobiosensors which should be taken into consideration before declaring these nano‐weapons as the ideal futuristic gold standard of diagnosis has also been accounted for here.
The
noteworthy beneficiary to date in nanotechnology is cancer
management. Nanorobots are developed as the result of advancements
in the nanostructure, robotics, healthcare, and computer systems.
These devices at the nanoscale level are beneficial in the prevention,
diagnosis, and treatment of various health conditions notably cancer.
Though these structures have distinct potentialities, the usage of
inorganic substances in their construction can affect their performance
and can cause health issues in the body. To overcome this, naturally
inspired substances are incorporated in the fabrication process of
nanorobots termed biomimetic nanorobots that can overcome the immunological
responses and reduce the side effects with effective functionalization.
These biomimetic nanorobots can widen the opportunities in cancer
imaging and therapy. Herein, an up-to-date review of biomimetic nanorobots
along with their applications in cancer management is provided. Furthermore,
the safety issues and future directions of biomimetic nanorobots to
achieve clinical translation are also stated.
