According to the American Nano Society, nanotechnology is a field of science which deals with the study of nano size. In medical field, gold nanoparticles, titanium dioxide, zinc oxide, and calcium phosphate are majorly utilized nanoparticles. These particles collectively accounted for a market share of over 30%.However, of these gold nanoparticles have witnessed the significant growth due to their ease of preparation, low toxicity , and ability to attach to specific biological molecules for diagnosis or treatment. Furthermore, there are majorly four types of gold nanoparticles available such as gold nanorods, gold-silica nanoshells, gold colloid, and gold-gold sulphide nanoparticles.
Advent of new technology enabled the ability of nanoparticles to pass through the blood vessels and detect the tumor location or deliver drug at the targeted site. Gold nanoparticles are also used to treat rheumatoid arthritis, hepatitis, fungal infections, cancer, heart diseases, various infections, and tumors.The color scattered by gold nanoparticles helps in biological imaging.
Increasing investment in R&D activities, growth of gold nanomaterials in countries such as China, Taiwan, and South Korea, demand for compact devices, and superior conduction and optical properties of gold nanoparticles are key factors expected to drive the global gold nanoparticles market in the future. Additionally, increasing acceptance of gold nanoparticles to treat cancer due to their higher efficacy is anticipated to show positive impact on the gold nanoparticles market. Presently, nanotechnology is in infancy stage however, owing to anticipated launch of gold nanoparticles in the future is anticipated to pull the market growth. Currently, several nanodrugs are under clinical trials such as Aurimmune and Auroshell.
Aurimmune (Cytimmune Sciences, Rockville, MD) is a gold nanoparticle attached to a recombinant human tumor necrosis factor α (TNF-α). rhTNF- α has the ability to accumulate in the tumor and exert its antitumor activity. Similarly, Auroshell is under advance clinical trial for the treatment of head and neck cancer. However, biocompatibility of gold nanoparticles is a major issue which is expected to challenge the market growth. Thus, to overcome the restrain, companies like nanoComposix developed an ecofriendly method for biosynthesis of gold nanoparticles.
Gold nanoparticles market can be majorly segmented based on application and end users. Depending on the application of gold nanoparticlesin the medical field they could be further segmented into drug delivery or therapeutics, biomarkers, contrast agent, DNA delivery, and radiotherapy. By end users gold nanoparticles market is segmented into pharmaceuticles, cosmetics, and biomedical industry. Geographically, gold nanoparticles market is classified into North America, Europe, Asia Pacific, Latin America, Middle East and Africa, and rest of the world. Gold nanoparticles used in drug delivery or in therapeutics application segment accounted for the largest share of the market in 2013. In geography segment, North America dominated the glod nanoparticles market in 2013 by accounting more than 30% share due to increasing R&D expenditures by the companies and universities, and expanding medical diagnostic field. Europe was identified as the second largest market in 2013, accounting for over 20% of the total market revenues.
In addition, Europe gold nanoparticles market is anticipated to expand at a stable rate in the near future due to increasing demand of nanoparticles. Asia – Pacific is anticipated as the fastest growing market for gold nanoparticles in the future due to increasing prevalence of diseases such as cancer, and HIV, technological advancements, and increasing awareness of physicians about the nanoparticles.
Some of the key players operating in the gold nanoparticles market include BBI Solutions, NanoSphere, Inc., Nanostellar, Inc., Sigma Aldrich Corporation, and Cytodiagnostics, Inc. In addition, other emerging companies include Metalor Technologies SA, and Johnson Matthey.
