I've been looking at some papers regarding the synthesis and characterization of different inorganic materials and I am becoming interested with this topic.
As you have probably determined, the possibilities are endless. There seems to be new ideas or improvements on ideas that are being generated daily. Edson, gave an excellent response in that high throughput and low cost are quite important from a commercial aspect. When something can become a part of our everyday lives, a true impact in society has obviously been made. Silicon based nanodevices are always attractive because it lends itself to opportunities in established companies because Si is the basis for the current nano structures in industry whether they be transistors or nano-electromechanical-systems (NEMS), for example. There is a lot of research going on in flexible electronics that use inorganic materials. Silicon and II-VI compound materials have found some promise.
There are different kind of inorganic nano materials. Every inorganic materials have different properties such as conducting, insulating, semiconducting, Thermal, Optical as well catalytic property etc., So the application of inorganic nanomaterials depending upon your choice of materials. if you are choosing semiconducting materials, you can do Photovoltaic systems, optical as well as catalytic applications. For example if you choose TiO2 nanomaterials will be applied for many applications like solar cells, cosmetics, photocatalytic and also for drug delivery systems.
All the inorganic nano structured materials can be applied for suitable applications depending upon its property wise.
Our recent paper describe the usage of NZVI (nanoparticles of zero-valent iron) against cyanobacterial bloooms (Marsalek et al., 2012 - Environmental science and technology)
