Bengaluru researchers develop durable sensor to detect explosives
As per the department of science and technology (DST), the innovation — based on surface-enhanced Raman spectroscopy (SERS) — overcomes long-standing limitations in the field by improving both sensitivity and long-term stability.
The breakthrough was achieved by Jil Rose Perutil, S Prashanth, Channabasaveshwar V Yelamaggad, Pavan Nukala, and Neena S John from the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru, an autonomous institute of DST.

"The team engineered a multilayer nanomaterial combining reduced graphene oxide (rGO), silver nanoparticles, and cerium oxide on a glass substrate — each layer serving a distinct role in improving performance," DST said.
Silver, though excellent at amplifying molecular "fingerprint" signals essential for SERS, tends to degrade in humid or warm environments. A protective coating of cerium oxide solves this by shielding the silver layer from environmental wear while enhancing charge transfer, further boosting signal clarity.

The rGO layer, meanwhile, suppresses unwanted background fluorescence from silver, allowing the actual detection signal to stand out.
"The researchers demonstrated the system's high sensitivity using 4-mercaptobenzoic acid as a model analyte and achieved detection limits as low as 10 nanomolar. More significantly, the same platform could detect explosives like TNT and RDX at similar nanomolar levels," DST said.
Tests in environmental chambers confirmed that the sensor maintained high performance even in extreme conditions — 90% humidity and 7 °C — showcasing its potential for rugged, field-ready deployment.
"Developed using a physical vapour deposition technique, the sensor's fabrication process is uniform and scalable, suggesting commercial promise. With its combination of durability, simplicity, and precision, the team says the platform could be used in airport screening systems, defence applications, or even environmental monitoring where detecting trace contaminants rapidly is critical," DST added.

Interested customers can book by paying a token amount of Rs 51,000. Bookings can be made through 13 MG Select dealerships located in major cities like Mumbai, Delhi, and Bengaluru, or via the company's official website. The MG Cyberster is India's first electric roadster and currently has no direct rivals in the Indian market. However, in terms of size and proportions, it can be compared to the BMW Z4 .

However, for those who had pre-reserved the car previously, it's available at Rs 72.49 lakh (both prices, ex-showroom). The BMW Z4 is offered in three variants - M40i priced at Rs 92.9 lakh, M40i Pure impulse AT priced at Rs 96.9 lakh and M40i Pure impulse MT priced at Rs 97.9 lakh (all prices, ex-showroom). The MG Cyberster undercuts the BMW Z4 by a significant margin. Even at its standard price of Rs 74.99 lakh, it's at least Rs 17.9 lakh more affordable than the entry-level BMW Z4 M40i priced at Rs 92.9 lakh. Both cars are bought in India via the CBU route. MG Cyberster vs BMW Z4: Dimensions Dimension-wise, the Cyberster measures 4,533 mm in length, 1,912 mm in width, and 1,328 mm in height, with a 2,689 mm wheelbase. It gets 20-inch wheels. The Z4 measures 4324 mm in length, 1864 mm in width 1304 mm in height and has a wheelbase of 2470 mm. It gets 19-inch wheels. The MG Cyberster is 209 mm longer, 48 mm wider, and 24 mm taller than the BMW Z4. It also has a 219 mm longer wheelbase, which should translate to better cabin space. Additionally, the Cyberster gets larger 20-inch wheels compared to the Z4's 19-inch wheels. MG Cyberster vs BMW Z4: Features The MG Cyberster gets three screens, including a vertically stacked infotainment system angled towards the driver. Features include wireless Apple CarPlay/Android Auto, in-built 5G, connected car tech, wireless charging, dual-zone climate control, ventilated seats, and a premium Bose audio system. It will also offer Qualcomm Snapdragon 8155 chip, regenerative braking, multiple airbags, Level-2 ADAS, and more. The BMW Z4 gets a 10.25-inch touchscreen infotainment system with iDrive 7.0 OS, digital driver's display, GPS with 3D maps, touch controller, ambient lighting, powered driver and passenger seat with memory function, dual claimed zone AC, connected car tech, 4 airbags, dynamic traction control, dynamic stability control, cornering brake control and more.
