Researchers at Indian Institute of Technology (IIT) Bhubaneswar have developed a portable, low-cost, and field-deployable device named "ArsenSafe" for rapid detection of arsenic contamination in drinking water.

The device has been developed by the Sensors and Spectroscopy Research Group of the School of Electrical and Computer Sciences (SECS) and is aimed at addressing the growing public health challenge posed by arsenic-contaminated groundwater.

Key Features of ArsenSafe

Portable and handheld device.

Low-cost and easy to use.

Enables rapid detection of arsenic in drinking water.

Suitable for field deployment in rural and remote areas.

Does not require sophisticated laboratory infrastructure.

Eliminates the need for chemical reagents.

Technology Used:

ArsenSafe uses a Reduced Graphene Oxide (rGO)-based sensing system, which enables faster, more accurate, and cost-effective detection of arsenic contamination in water.

The technology makes arsenic testing more accessible, particularly in regions where laboratory facilities are limited.

Startup Involvement:

The device has been developed through Nano Semic Pvt. Ltd., a startup incubated at the Research and Entrepreneurship Park of IIT Bhubaneswar.

This collaboration highlights the role of academic institutions and startups in developing innovative solutions to address public health and environmental challenges.

About Arsenic Contamination:

Arsenic is a naturally occurring toxic element found in groundwater in several regions of the world.

Chronic arsenic exposure can cause Arsenicosis, a serious health condition.

The World Health Organization (WHO) recommends a maximum arsenic concentration of 10 micrograms per litre (10 ppb) in drinking water.

Arsenic-Affected States in India

Major arsenic contamination has been reported in:

West Bengal

Bihar

Uttar Pradesh

Assam

Jharkhand

Manipur
