Another used nanoparticles as a companion to other treatments. Hence, several techniques were used in the past to produce an apatite coating on titanium. For example, sensors . Scientists add some bizarre things to vaccines, such as aluminium and extracts from shark livers. In the end this findings would allow to design a more durable and longer lasting hip or knee replacements and to reduce the chances of the implant getting loose. Devices such as Flash memory chips, antimicrobial and antibacterial coatings for mouse, keyboard. One of these processes is called Sol-gel and it immerses fabrics in a gel solution to deposit nanoparticles into the material. Science. Nanoparticulate materials have many uses. The approaches used in constructing nano-biomaterials are schematically presented below (see Figure 1). Surface area. For example, in studies of nanoparticles in raw sewage, scientists used SANS measurements, in which neutrons readily penetrated the turbid sewage and scattered strongly from the nanoparticles, to follow the aggregation behaviour of the particles over time.
