Nano applications and technology

Growth and development of nanotechnology has exploded over recent years, though as shown in [link] , below this trend was lead by the United States with a massive increase in patenting activity starting in the mid 1990s (Huang et al. 2004).

To date, nanotechnology has seen selective application in high-end products, most of which is within high-performance applications for the automotive and aerospace sectors.

Having established this presence in performance engineering applications, nanotechnology is now becoming embedded within IT applications such as microprocessors and memory chips built using new nanoscale processes (Lux Research, 2004). By 2014 it is projected that 50% of electronics and IT will incorporate nanotechnology (Lux Research 2004).

Although Bio-Life Science is currently the leading sector in nanotechnology development, the rate of innovation across all sectors is significant. Other technological fields that experienced rapid growth in patenting activity in 2003 were those relating to transistors and other solid-state devices, semiconductor device manufacturing, optical waveguides, and electric lamp and discharge (Huang et al. 2004). [link] shows an overview of sectoral breakdown of nanotechnology. It is worth noting that sectors such as Materials and Chemicals are in effect enablers for broader sectors, and integrate into the supply and value chains of other sectors. (OSTP 2005). Examples of such materials are carbon nanotubes and quantum dots, which have applications in all sectors.

Industrially it has been shown that the leading participants in nanotechnology development are the large-scale industrial actors such as IBM, Intel, and L’Oreal, reflecting the complex and expensive nature of development (EmTech 2005).

In terms of economic impact it is projected that 11% of total manufacturing jobs worldwide will involve manufacture of products incorporating nanotechnology. This will have a result in a paradigm shift in requirements upon supply chains and shift the nature of competition by introducing radical new entrants. This shift is set to accelerate as mass production processes are developed and the cost of materials is driven down, making product opportunities more viable.

Nano market growth

Although the most ambitious, potentially world-changing nanotechnology applications are still in development, marketplaces associated with nanotechnologies are already forecasted to be worth billions and are projected to exceed $2.6 trillion within 15 years (Texas Nanotechnology Report, 2008).

Global

Due to the potential impacts of nanotechnology, there has been, and is, a strong global interest across governments, business, venture capitalists, and academic researchers. From the period of 1997 to 2005, approximately $18 billion were invested globally in nanotechnology by national and local governments (Cientifica 2006). Governments in the United State, Japan, and Western Europe are among top global nano technology spenders, with global collective governmental spending annually some ~$4.6 billion. This represents just under 50% of total expenditure with the remainder coming from major corporations including a minor proportion from venture capitalists (Lux Research, 2008). However, despite the initial lead of the United States in nanotechnology investment it is now been overtaken by Europe for government expenditure and by Asia for corporate investment (Nano Report, 2006).

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials

I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
