COVID-19, R U still there?

Background

COVID-19 has taught us to be more self-sufficient, patience, and more prepared for the next time when COVID-19’s family member would decide to come back to Earth and visit this beautiful creation again. Would like to learn more about COVID-19?

COVID-19 is the most recently discovered infectious disease caused by β (beta) coronavirus. It is a non-segmented positive-sense RNA virus. This new virus was unknown before the outbreak began in Wuhan, China, in December 2019.

Although no concrete evidence has been established yet, the coronavirus is primarily transmitted through inhalation. Infected patients may experience mild systems such as, a sore throat, headache, fever, dry cough, shortness of breath, and fatigue. However, in severe cases, viruses attack on the lungs causing pneumonia. Air sacs in lungs known as alveoli, exchange oxygen with blood and transported throughout the body, and when the coronavirus attaches to these alveoli cells, they begin to replicate within the cells. When the immune system attempts to destroy the viruses, the action results in the inflammatory response, and causes fluid accumulation in the lungs. As the lungs are filled with fluid, the body’s available oxygen decreases, which can lead to organ injury and death.

Normally, seven days is the incubation period of this infection. After seven days B lymphocyte of our immune system starts to produce IgM antibody. Production of IgM antibody reaches to the peak level after 10 days of infection, and eventually disappears after 30 days. Similarly, after 12 days of infection, our immune system starts to produce IgG antibody. Peak production of IgG antibody reaches after 20 days and may remain for a long time.

Reverse transcriptase real time PCR (RT-qPCR) and rapid antibody tests are major diagnostic tools, which are now in use universally. RT-qPCR is a gold standard method, that can detect viruses from the first day to up to 25 days of viral onset whereas, IgM rapid antibody test is useful after 10 days to 30 days of viral onset. Similarly, IgG rapid antibody test is useful after 25 days of viral onset.

Ultra-sensitive Sensors are not an Option, they are a Necessity 

Before, sensors were used to be just used for testing glucose level in humans, but now they have been developed to detect many dangerous diseases. As sensors have evolved, they now are needed more than ever with diseases such as many forms of cancer, and COVID 19 are prevalent. The problem is that there is a disconnect between what we need these sensors to do, and what they are currently capable of doing. That’s why we need ultra-sensitive sensors in order to detect diseases at the earliest stages because so many often get missed as a result of current detection limits. This is why we at Seed NanoTech, have come up with the concept of magnetoplasmonic sensor with sharp resonances, and high sensitivity and detection limits. Our approach is based on the combination of a specially designed metallic and ferromagnetic layers that are optimized to detect changes in the environment refractive index,  examined using magnetic activity in addition to the plasmonic and optical activities.

Where magnetoplasmonics meets biology

Magneto-plasmonics is a relatively new field that has many great potential applications in biomedicine and biomedical technologies such as ultra-sensitive biosensing and bio-detection, bio-imaging, bio-therapy, drug-delivery, and nano-imaging, to name a few. A deep understanding of various factors influencing magnetoplasmon properties is an important step in the effort to design new magnetic sensors and devices. Although some progress on plasmonics has been achieved in the last few years, there is still a strong need to further investigate magneto-plasmonics, in order to better tune and control magneto-optic properties, as well as to increase the sensitivity of the magnetic bio-sensor through modification of the optical radiation, magnetic field, and structure.

This new field merges the physics of nano-magnetics, where biological samples such as cells and DNA are made to interact with magnetic moments of material in the transverse direction, and nano-optics, where biological samples are made to interact with optical radiation in visible, infra-red, and telecommunication wavelength ranges. In a similar manner, it merges nano-plasmonics where biological samples are made to interact with surface plasmonic wave fields, also referred to as evanescent radiation fields.
