Problem:

UNICEF estimates that >700 children die globally every day due to diarrhoeal diseases transmitted primarily via faecally contaminated water, while water consumed by >2 billion people has not been tested for fecal contaminations. In Nepal alone >8,000 children die every year due to water-borne diseases, with >80% of population lacking safe drinking water. Lack of low-cost and rapid water surveillance methodologies is one of the major bottlenecks to address this issue. Prevalent methodologies are impractical to implement in the developing countries like Nepal, as they require laboratory infrastructure and/or an incubation period of 24-48 hours.

Our solution:

A reagentless system, based on our unique ”optical engine” working in the deep-UV, to detect fecal contamination in water based on native fluorescence of proteins, mainly those containing Tryptophan and Tyrosine amino acids typically synthesized by the fecal coliforms.

Our solution packaged with automated Chlorine disinfection:

We have been developing an automatic measurement and disinfection which will take the results of the measurement of our system to control the dose of chlorination.

History of this technology and partnerships:

• The project which aimed for developing this technology was was initially funded by The World Academy of Sciences (TWAS)/sida and UNESCO which funded several key equipment to develop this technology.
• The optics component of this research, and development of the first prototype was done in collaboration with Prof. Thomas Krauss’s team at the University of York. The project was funded by UK’s Engineering and Physical Research Council and Global Challenges Research Fund
• Optical Foundation provided funding for piloting this technology
• Dr. Marcel van der Horst’s team in Amsterdam University of Applied Sciences supported us in the development of amplifier electronics used in this technology
• Diyalo Foundation and Global School for Entrepreneurship has been supporting us towards developing business strategies and securing international collaboration and network for taking this technology to the market.

Capabilities

• Real-time (<1 min), low-cost (<$1000 for a basic system), portable (< 1000 cm3; < 1 kg) and user-friendly (basic traffic-light indicators according to WHO risk categories)
• 96% sensitivity to detect fecal contamination
• Detection of other contaminants in drinking water

Example applications :

• Internal Quality Control: Identify faults in the purification system or distribution system
• Regulatory Surveillance: Instantly know the quality of drinking water in the market
• Environment: Quantify bacterial contaminations, efficiency of treatment
• Livestock Farming and Food Processing: Identify bacterial contaminations before livestocks drink the water
• Community Water Assurance: Instantly know the quality of water supplied to your community

Features To Be Added In The Next Feature Upgrades

• Fouling Detection
• Turbidity Measurement (0.25-500 NTU)
• Conductivity/TDS (25 μS/cm - 50,000 μS/cm)
• Inline Continuous Monitoring and Data Logging
• Local Alarm
• IoT integration (Data, Alarm, SMS)

Nano3D: Imaging And Flexures

Nano3D imaging and flexures can be ordered from our marketing and sales partner Nabla-cubed Innovation Pvt Ltd.

Problem:

Nanotechnology has been driving several innovations of the modern era from lighting, displays and communications to modern sensing, electronics, computing and quantum technologies. However, research and development in nanotechnologies are prohibitively costly - unsurprisingly -  because these activities require instruments with nanometer-scale precision. Low-cost imaging and positioning systems  is a key for developing countries to take part in this key driver of innovations. Our solution: We have developed a low-cost  imaging and positioning system with sub-micron precision which uses 3D-printed flexures for motion control and white-light interferometry for 3-D imaging.
