In the heart of India, researchers are brewing up a storm in the world of nanotechnology, using a humble root extract to create a powerhouse of therapeutic potential. Nayan Kumar Sishu, a researcher from the Department of Biotechnology at Vellore Institute of Technology (VIT), has led a team to develop zinc oxide nanoparticles (ZnO NPs) using the root extract of chicory (Cichorium intybus L.), a plant more commonly known for its use in coffee substitutes and salads. The results, published in the journal ‘Green Chemistry Letters and Reviews’ (which translates to ‘Green Chemistry Letters and Reviews’), hint at a future where this tiny innovation could make big waves in medicine and beyond.
The team’s work focuses on the bio-fabrication of ZnO NPs using chicory root aqueous extract, a process that’s not only eco-friendly but also cost-effective. “We’ve shown that these nanoparticles have promising therapeutic applications,” Sishu explains. “They exhibit significant antioxidant, antidiabetic, and anticancer properties, making them a potential game-changer in biomedical research.”
The chicory-mediated ZnO NPs (CIRAE-ZnO NPs) were put through a rigorous series of tests, including UV, FTIR, XRD, zeta potential, DLS, FE-SEM, and HR-TEM analyses. The high-resolution transmission electron microscopy (HR-TEM) revealed that the nanoparticles were quasi-spherical, with an average size of about 26.66 nm. But size isn’t everything. These tiny particles pack a punch, with impressive IC50 values in various assays, indicating their potent antioxidant and anti-inflammatory activities.
One of the most exciting aspects of this research is its potential impact on the energy sector. ZnO NPs are already used in solar cells, and the enhanced properties of CIRAE-ZnO NPs could lead to more efficient and cost-effective solar energy solutions. “The commercial implications are vast,” Sishu notes. “From medicine to energy, these nanoparticles could revolutionize multiple industries.”
The CIRAE-ZnO NPs also showed promising results in antidiabetic assays, with significant inhibitory activity against α-glucosidase and α-amylase. This could pave the way for new treatments for diabetes, a global health concern. Moreover, the nanoparticles exhibited moderate thrombolytic activity and low hemolytic activity, suggesting their potential use in cardiovascular therapies.
In the realm of oncology, the CIRAE-ZnO NPs demonstrated significant cytotoxicity in A549 (lung cancer) and 3T3-L1 (pre-adipocyte) cells, with lower risk to non-target organisms like Artemia salina. This selectivity is crucial for developing targeted cancer therapies with minimal side effects.
The implications of this research are far-reaching. As we grapple with global health challenges and the need for sustainable energy solutions, innovations like CIRAE-ZnO NPs offer a beacon of hope. They embody the spirit of green chemistry, harnessing the power of nature to create sustainable, effective solutions.
As we look to the future, it’s clear that nanotechnology will play a pivotal role in shaping our world. The work of Sishu and his team is a testament to the power of interdisciplinary research, blending biology, chemistry, and engineering to create something truly transformative. As they continue to explore the potential of CIRAE-ZnO NPs, one thing is certain: the future of medicine and energy is looking smaller, but mightier, than ever before.
