Guwahati Scientists Create Eco-Friendly, Low-Cost Device to Detect Cholesterol Early
A group of researchers from the Institute of Advanced Study in Science and Technology (IASST), Guwahati, has developed an innovative and eco-friendly optical sensing platform to detect cholesterol levels. This new technology offers a low-cost solution for early diagnosis of serious health issues such as heart disease, hypertension, atherosclerosis, venous thrombosis, myocardial infarction, and even cancer.
The research team, led by Prof. Neelotpal Sen Sarma (Retired Professor), Dr. Asis Bala (Associate Professor), and Nasrin Sultana (DST INSPIRE Senior Research Fellow), has crafted this sensitive platform using silk fibre integrated with phosphorene quantum dots. They embedded this material within a cellulose nitrate membrane, transforming it into an efficient electrical sensing tool for cholesterol monitoring.
According to the Ministry of Science & Technology, the device is designed to help spot early warning signs of multiple life-threatening conditions, improving chances of timely intervention.
Their findings have been published in the Nanoscale journal, a prestigious publication of the Royal Society of Chemistry.
Cholesterol, a vital lipid produced by the liver, plays a key role in human health. However, an imbalance can lead to serious complications. There are two main types of cholesterol: LDL (low-density lipoprotein), known as 'bad' cholesterol because it can build up in artery walls, and HDL (high-density lipoprotein), or 'good' cholesterol, which helps remove LDL from the bloodstream. Maintaining a healthy balance between the two is essential.
This breakthrough platform could pave the way for affordable, eco-friendly diagnostic tools in healthcare, especially beneficial for early-stage disease detection.
