What are the potential applications of nanotechnology in the Philippines?

In the area of agriculture , notable products developed in the strengthened nanotechnology programs of the University of the Philippines Los Baños include: 1) nanosilica-based fertilizer that increases germination and growth rate of tomatoes; 2) fruitect® coating technology which boosts shelf life of high valued fruits

What are the benefits and concerns of using nanotechnology?

Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources and life-saving medical treatments. Potential disadvantages include economic disruption and possible threats to security , privacy, health and the environment.

How do you explain nanotechnology?

Nanotechnology is defined as the study and use of structures between 1 nanometer and 100 nanometers in size. To give you an idea of how small that is, it would take eight hundred 100 nanometer particles side by side to match the width of a human hair.

Is Nanotechnology good or bad?

Nanoparticles do hold out much environmental promise. The same reactivity that makes them harmful in the body also means they can break down dangerous chemicals in toxic waste – or anywhere, for that matter. And their use in electronics drastically reduces power demand, which could cut greenhouse gases.
