Trailblazing Achievement in Rural Karnataka Science

Four high school girls from rural and tribal areas of Karnataka have etched their names in scientific history by co-authoring a research paper published in a prestigious international journal. This remarkable feat underscores the untapped potential in India's underserved communities when given the right opportunities. Their work on eco-friendly copper oxide nanoparticles offers practical solutions for water purification, addressing a critical need in rural regions plagued by contaminated water sources.

Meet the Young Pioneers

The quartet—Kirat Kaur from Bidar (11th standard), S. Yamini from Hosadoddi village (11th standard), Reshma J.V. from Hosahalli in H.D. Kote taluk (11th standard, Jenu Kuruba tribal community, student at Viveka Tribal Centre for Learning in Nagarahole forest region), and Lakshmi G. from Kaggalipura village (10th standard)—hail from modest backgrounds. Many are first-generation learners, defying odds stacked against them due to geographic isolation and socio-economic barriers.

Reshma J.V., belonging to the Particularly Vulnerable Tribal Group (PVTG) Jenu Kuruba, represents a community traditionally reliant on forest produce. Her journey from forest fringes to a Scopus-indexed publication symbolizes hope for thousands like her.

The Groundbreaking Research Unveiled

Their paper, titled "Green synthesis of saponin-capped copper (II) oxide (CuO) nanoparticles and their efficacy in photocatalytic dye degradation," appeared in Sustainable Chemistry One World, a peer-reviewed Scopus-indexed journal by Elsevier. Conducted from March to August 2024, the study demonstrates an environmentally benign method to produce CuO nanoparticles using saponins—natural surfactants extracted from plants like soapnuts or fenugreek.

Green synthesis refers to the production of nanomaterials using biological agents instead of harsh chemicals, reducing toxicity and environmental harm. The process involves mixing plant extracts with copper salts, allowing saponins to cap and stabilize the nanoparticles, which are tiny particles (1-100 nanometers in size) exhibiting unique properties due to high surface area.

Step-by-Step Scientific Process

The girls followed a meticulous methodology:

• Extraction: Saponins isolated from plant sources via solvent extraction.
• Synthesis: Copper precursors reacted with extracts under controlled conditions (temperature, pH).
• Characterization: Nanoparticles analyzed using UV-Vis spectroscopy, XRD (X-ray diffraction for crystal structure), SEM (scanning electron microscopy for morphology), and FTIR (Fourier-transform infrared spectroscopy for functional groups).
• Application Testing: Photocatalytic degradation of dyes like methylene blue under visible light, measuring efficiency via absorbance reduction.
• Biological Assays: Antibacterial activity against pathogens like E. coli via zone of inhibition; antioxidant potential using DPPH assay.

Role of Anveshana Programme and Mentors

This achievement stems from Anveshana, Prayoga Institute of Education Research's flagship fully funded high school research initiative in Bengaluru. Targeting grades 9-12 students from under-resourced schools, it immerses participants in real labs, field visits, and mentorship. Themes include green chemistry, ecology, and materials science.Learn more about Anveshana

Mentors Subhadip Senapati (lead chemist), Vagdevi Rao K.C. (botany), and Parikshit Kumar (green energy) simplified complex concepts via animations and hands-on demos. "We assigned a subset of our ongoing research to them after they showed interest," Kumar noted.

National Recognition on Science Day

On February 26, 2026—National Science Day—the girls were felicitated by Karnataka's Department of Science and Technology. Attendees included Science Minister N.S. Boseraju, Higher Education Minister M.C. Sudhakar, and ISRO veteran A.S. Kiran Kumar. The event celebrated their contribution to sustainable technologies.

Challenges Facing Rural and Tribal Education

Despite this success, hurdles persist. Karnataka's tribal (Scheduled Tribe or ST) girls face a 42% dropout rate from upper primary to secondary levels—double the state average. Overall school dropout rose to 20.4% in 2024-25. Science participation is low due to poor infrastructure, teacher shortages, and cultural barriers. Jenu Kurubas, like Reshma's community, grapple with seasonal migration and limited access.

Reshma reflected: "For tribal students, it's not lack of ability but access. With opportunities, we can shine."

Broader Impacts and Applications

The nanoparticles' photocatalytic prowess degrades industrial dyes, vital for textile-polluted regions like Karnataka's rural belts. Antibacterial properties combat waterborne diseases affecting millions. Antioxidant effects hint at biomedical uses, like drug delivery.

• Low-cost: Plant-based, scalable for villages.
• Eco-friendly: No toxic solvents.
• Versatile: Water purification, textiles, healthcare.

Initiatives Boosting Rural Science Talent

Karnataka's efforts include Innovation Labs in 60+ residential schools, Science for All outreach, and Prayoga's expansions. Nationally, INSPIRE (Innovation in Science Pursuit for Inspired Research) awards scholarships to top young scientists. KVPY fosters research aptitude.

Prayoga's model—research as pedagogy—builds critical thinking, with past cohorts publishing in journals like Journal of Emerging Investigators.

Pathways to Higher Education and Careers

This breakthrough paves the way for university pursuits. Talents like these can target IITs, IISc via JEE/NEET, or research programs. Craft a winning academic CV highlighting such publications.

Stakeholders urge scaling Anveshana: educators for mentorship, policymakers for funding, communities for support. Future outlooks include more rural publications, addressing India's GERD lag (0.64% GDP on R&D).
