Nanosensors are tiny devices that sense physical quantities and turn them into detectable and analysed signals. Numerous methods for creating nanosensors have been proposed, including top-down lithography, bottom-up assembly, and molecular self-assembly.
Nanosensors of various varieties are on the market and under research for a variety of applications, most notably in the defence, environmental, and healthcare industries.
The essential workflow for these sensors is the same: selective binding of an analyte, signal production from the interaction of the nanosensor with the bio-element, and signal processing into meaningful measures.
Magnetic nanosensors are MNPs that have sensing moieties that interact with proteins, DNA, or cell surfaces.
The Global Magnetic nanosensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Magnetic-Nanosensor-Based Virus and Pathogen Detection Strategies before and during COVID-19.The world’s healthcare system and financial stability are at risk from the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus illness (COVID-19).
In order to effectively execute control and containment methods and prevent the spread of COVID-19, a quick and correct diagnosis for SARS-CoV-2 is crucial.
There are currently no particular medications or vaccinations available for COVID-19. The frontiers of contemporary biosensing and magnetic fields are represented by the growing field of magnetic nanosensing.
the explosive expansion of biological and biomedical uses for magnetic instruments. Current diagnostic techniques have been scaled down to the nanoscale by recent developments in magnetic nanomaterials and nanotechnologies, pushing the detection threshold for early-stage illness diagnosis.
Before COVID-19, magnetic nanosensors were used to detect viruses and other pathogens.Magnetoresistance, magnetic particle spectroscopy, and nuclear magnetic resonance are examples of magnetic nanosensing methods.
In order to manage the SARS-CoV-2 outbreak and stop other epidemics, plug-and-play diagnostics are another goal of magnetic point-of-care diagnostic kits. Also presented are alternative platforms that employ magnetic nanoparticles as supplemental tools for improved pathogen and virus identification.
The objective is to provide information on the capabilities of the SARS-CoV-2 diagnostic and surveillance platforms.
