Nanotechnology to take the Pharmaceuticals Sector to a New Level in the next 10 Years!

Healthcare Pharmaceuticals

Technological advancements have made a foray into every vertical, and medicines are no exception. These days, it is seen that modernization is moving towards better development of diagnostic tests and point-of-care devices.

Biomarkers come across as components that biological samples are subject to, and used to treat specific diseases. Doctors do analyze the patients’ biological samples for checking on the health condition or monitoring a specific therapy’s progress. Conventionally, the samples need to be diluted and purified prior to analysis. The existing medical diagnostic techniques do rely on laboratories and healthcare facilities for these day-to-day analyses. This process could be cumbersome. This is where point-of-care devices come into picture. They are petite, automated instruments that have the capability to perform diagnostics even in decentralized locations. Biomarkers are, in fact, looked upon as one of the most conducive alternative medicines therapies.

What are the Challenges over here?

There are a few challenges encountered herein as well. For instance – for certain ailments and infections, biomarkers are present in pretty small quantities, which does impose challenge of developing sensitive detection techniques. This could be addresses by increasing the entire surface area of biosensor, but the same surfaces could be easily contaminated and clogged, thereby rendering them useless after one use.

Professor Cho, Yoon-Kyoung at the Center for Soft and Living Matter, that too, within the IBS (Institute for Basic Science) in Ulsan (South Korea) has mentioned about tabling a biosensor by making use of method for generating nanoporous and nanostructured surfaces. This method actually solves the problem of littering by proteins. As such, it could be inferred that nanomedicines are the future of pharmaceuticals.

What’s with the Nanostructured Substrates?

Though initially there were no known methods for reliably creating electrodes using nanoporous and nanostructured substrates, the team mentioned above has floored a simple method for generating such materials. This mechanism implies applying electric pulses to flat gold surface in presence of surfactant and sodium chloride that could render “micelles” in the solution. The electric pulses do drive reaction of redepositing gold from surface and grow nanostructures to form nanopores.

These researchers have demonstrated the new-fangled technology by having a biosensor to detect prostate cancer. With absolutely no need of preprocessing steps or dilution, the technology could be used effortlessly for POC (point-of-care) diagnosis of cancer. Telemedicine being the norm during as well as post-Covid era, this way of treatment may not be feasible long distance, but advanced research on this count may result in more number of POC diagnostic centers.

Medical science will continue to grow beyond bounds, and biosensors will find their application across almost every ailment in the near future. There would be no stoppage to the medicines’ vertical in the near future. With nanotechnology witnessing an upscalation throughout, it would be interesting to know about the inventions in this regard. Therefore, with cancer, the other fatal ailments like heart disorders and brain tumors could also be looked into.

It’s a “Wait and Watch” approach through the Medical World!
