Nanobiotechnology as a Tool for the Surveillance of Waterborne Pathogens in Remote Areas

Water is essential for life but also facilitates the transmission of pathogens, particularly in remote areas with limited access to clean water. Climate change exacerbates the presence of waterborne pathogens, increasing public health risks and highlighting the need for effective monitoring systems. Traditional pathogen detection methods are often slow and resource-intensive, making them less viable in underdeveloped regions. Nanobiotechnology, an integration of nanotechnology and biotechnology, offers an alternative solution by enabling rapid and cost-effective surveillance of pathogens. Biological components such as proteins, antibodies, and DNA serve as analytes while nanoparticles serve as reporting systems. The unique properties of nanoparticles, such as their high surface area-to-volume ratio, allow for efficient pathogen detection, with results available in minutes. Nanobiotechnology-based biosensors can be deployed in remote areas, serving as early warning systems for water quality, and empowering local communities to monitor their water safety independently. Gold nanoparticle-based biosensors are widely used in nanobiotechnology due to their localized surface plasmon resonance that allows the detection of analytes with naked eyes. Nanobiotechnology plays a crucial role in addressing challenges arising from climate change and reducing the risks associated with waterborne diseases.
