“…TiO 2 nanoparticle can inactivate microorganisms under UV/solar irradiation by forming some reactive oxygen species (ROS) such as hydroxyl radical (OH), superoxide radical (O 2 -) and hydrogen peroxide (H 2 O 2 ) (Sunada, et al, 1998). ROS are formed by reaction of surface oxygen and water with positive cavities formed on TiO 2 crystal lattice during UV/solar irradiation (Huang, et al, 2005). When energy (derived from photon) that is equal to or is greater than the bandgap energy of the TiO 2 , electrons are released from valance band leaving holes and forming the so-called exciton.…”

As freshwater resource decreasing rapidly due to high rate of human population growth, many researchers have done studies to develop methods for producing freshwater supply. Seawater desalination is one of the method that has the credibility to be implemented. However, conventional seawater desalination processes suffer from a number of problems related to energy efficiency and cost. In spite of this, nanotechnology has been applied to the process. In this paper, we give an overview and explanations concerning the roles of nanotechnology in seawater desalination processes which consist of pretreatment, reverse osmosis (RO), and disinfection. In addition, the comparisons between conventional and nanotechnology-applied processes as related to its efficiency and effectiveness are also provided.

“…Experimental results showed that nano-MgO in conjunction with the uptake of halogens, in particular chloride, that effective destruction of the bacteria and bacterial spores was observed [14]. Another study was conducted which also covered the antimicrobial properties of nano-MgO and showed highly controlled synthesis of the particles with the ability to control particle size [15]. Through this process, using a range of Nano-Mg particle sizes ranging from 70nm down to around 8nm, it was a observed that there was significant antimicrobial activity that actually increased the with a decrease in particle size, in particular with B.subtilis [15].…”

It has been tested already in Phenylpropyl type interior paints and shown significant antimicrobial activity, this type of application could be applied in many medical facilities as well as households as a means to reduce contamination and pathogenesis to humans [15] .…”

Abstract:The need for new and effective/efficient antibacterial therapeutics and diagnostics is necessary if we want to be able to maintain and improve the protection against pathogenic bacteria. Bacteria are becoming increasingly resistant to traditionally used antibiotics and as a result are a major health concern. The number of deaths and hospitalizations due to bacteria is increasing. Current methods of bacterial diagnostics are inefficient as they lack speed and ultra sensitivity and cannot be performed on site. This is where nanomedicine is playing a vital role. The discovery of new and innovative materials through the improvement in fabrication techniques has seen the establishment of an influx of novel antibacterial therapeutics and diagnostics. The goal of this review is to highlight the research that has been done through the implementation of nanomaterials and nanotechnologies for antibacterial medical therapeutic and diagnostic.

The small-scale technology of Nano science is the science and engineering of making and using materials, functional structures, and devices on the order of nanometer scale. In scientific terms, 'Nano' means 10" 9 , where 1 nanometer is equivalent to one billionth of a meter. In other words, Nanotechnologies are the body of theories and techniques that allow the production and manipulation of minute objects that measure as little as one billionth of a meter (the nanometer). The term nano technology embraces many different fields and specialties, including engineering, chemistry, physics, electronics, and medicine; but all are concerned with bringing existing technologies down to a very small scale, measured in nanometers. Typically, nano-sized materials refer to the production of a collection of distinguishable units, each comprised of a limited number of atoms. These units have specific shape and have at least one of their dimensions ranging over order of a few nanometers. In contrast to bulk materials, the nano-sized materials have a distinctive size and shape, surface chemistry and topology. There are various types of nano-sized materials, and these include nano-
