In this paper the role of nanobiotechnology in the study of biological systems in water environment is presented. The functional nano-meter-scale structures in the cell such as genetic material, membranes, enzymes and molecular machines are decribed. The knowledge gained has applications in nanomedicine. Nanoparticles have practical applications in detection of water pollution and water purific...

The growing need for clean drinking water worldwide is one of the pressing issues of this century. The World Health Organization estimates that in 2005, 1.6 million children under the age of 5 died from causes due to unsafe drinking water. Low-pressure membrane filtration systems are likely to play an important role in water purification and reuse strategies. While these systems have low-cost a...

-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...

Why boil water when there are so many other options? These days, “boil it, peel it, or forget it” only goes so far with the unencumbered traveler. experience tells me that most hear “Boil it” and instantly go right to “Forget it!” Fortunately, there is an excellent resource to assist patients in choosing a personally acceptable portable water purification system. It’s called the Water Purificat...

A number of years ago the Green Chemistry Centre of Excellence at York discovered new high surface area forms of polysaccharides. Further study of these materials has found that after controlled thermal treatment they exhibit remarkable thermal properties, which have enabled us to make an entirely new class of materials with properties ranging from starch-like to carbon-like (see figure 1). Tra...
