Researchers, including an Indian-origin, have identified an advanced nanomaterial-based biosensing platform that detects, within seconds, antibodies specific to SARS-CoV-2, the virus responsible for the Covid-19 pandemic. In addition to testing, the platform will help to quantify patient immunological response to the new vaccines with precision, according to a paper published in the journal Advanced Materials.

“We utilized the latest advances in materials and manufacturing such as nanoparticle 3D printing to create a device that rapidly detects Covid-19 antibodies,” said researcher Rahul Panat, Associate Professor at Carnegie Mellon University in the US.

The testing platform identifies the presence of two of the virus’ antibodies, spike S1 protein and receptor-binding domain (RBD), in a very small drop of blood (about 5 microliters). Antibody concentrations can be extremely low and still detected below one picomolar (0.15 nanograms per milliliter). This detection happens through an electrochemical reaction within a handheld microfluidic device which sends results almost immediately to a simple interface on a smartphone.

According to the researchers, an additive manufacturing technology called aerosol jet 3D printing is responsible for the efficiency and accuracy of the testing platform. Tiny, inexpensive gold micropillar electrodes are printed at the nanoscale using aerosol droplets that are thermally sintered together.

This causes a rough, irregular surface that provides an increased surface area of the micropillars and an enhanced electrochemical reaction, where antibodies can latch on to antigens coated on the electrode. The specific geometry allows the micropillars to load more proteins for detection, resulting in very accurate, quick results.

The test has a very low error rate because the binding reaction between the antibody and antigen used in the device is highly selective. The researchers were able to exploit this natural design to their advantage. The results come at an urgent time during the Covid-19 pandemic. “Because our technique can quantify the immune response to vaccination, it is very relevant in the current environment,” Panat said.

An illustration of the rhyme Three Blind Mice

The Reformation in England is notorious for the religious impact it had on the countries of the world, and the current ongoing dispute among the various factions of Catholicism and Protestantism. Three Blind Mice, a rhyme that emerged in 1609, roughly a few years after the death of Queen Elizabeth I, is somewhat a dark reminder of the Dark Ages.

The Reformation began in England when King Henry VIII broke away from the Catholic church because he wanted to divorce his wife, to marry another woman who would bear him a male heir. His wife was a devout catholic and refused to give up her crown to another. The king decided to break away from the Papacy, from Rome, where the Catholic church reigned from. He created the Church of England, and put himself as the legal head. England broke into two factions based on religion, and after Henry's death, the country was plunged in war.

The pandemic brought about a global boom of entrepreneurship in 2020. Thousands of small businesses launched in the UK last year, and many were very successful. Some businesses started as passion projects, while others aimed to fill a hole in the pandemic market. Services and products, like at-home workouts, popped up all over social media from new and exciting businesses. The pandemic left many Brits financially unstable and scared for the future of their career. Launching their own business gave them something to focus on again and a small amount of income.

The brand focuses on creating quality products that are high efficacy made with all-natural and no chemicals in the formulae.

One of Indias fast growing Direct To Consumer (DTC) beauty and personal care brands, MyGlamm, launches its national TVC around the message 'All Natural #NoNasties today with actress Shraddha Kapoor, who is also an investor in the brand.

Kapoor who has a great millennial and Gen Z connect introduces 'My SUPERFOODS Kajal' which has No Parabens, No Mineral Oils, No Nasties while still being long-lasting and smudge-free and made with the goodness of nature. This is followed by many girls trying applying the kajal with confidence and while highlighting the ingredients Avocado Oil, Goji Berries, Vitamin E and Sunflower Seed Oil.
