1. Nanotechnology Contributions at a Glance
Nanotechnology is rapidly flourishing in a wide array of fields in general and medicine in particular. Nanotechnology provides a new wave of therapies on the horizon, giving rise to changing the world of medicine. Now, researchers are employing many nano-based treatments in medicine, which are not available to the public. The field is noticed as a global challenge, and quite a lot of worldwide research and business initiatives are in advance to achieve an efficient market position. The most dreaded diseases such as cancer face fundamental challenges, and nanotechnology has been proved to be a boon in making the treatment more target-specific. There are various ways that nanotechnology is revolutionizing medicine, namely nanobots, prenatal, disease prevention, medical records, sensory feedback, surgery, imaging, bone repair, drug delivery, stem cells, gene therapy, implanting devices, aging, cell repair, cancer treatment, nanocomputers, and so on.

NPD contains data about 1142 nanoproducts of 209 various types in this sector. These products are introduced into global markets by 434 companies, the headquarters of which are located in 45 different countries. The products are classified into pharmaceuticals, medical supplies, dentistry, tissue engineering, and prosthesis/orthopedy sub-industrial sectors.

A broad spectrum of drugs are categorized into the pharmaceutical sub-industrial sector, which are prescribed for the treatment of cancer, hepatitis C, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, tendinitis, bursitis, acute gout, schizophrenia, cachexia, anorexia, kidney transplant, chemotherapy induced nausea and vomiting pathophysiology, tumors, severe hypertriglyceridemia, hypercholesterolemia, AIDS-related Kaposi's Sarcoma, and Multiple Myeloma, to name but a few. The medical supplies includes the wound dressing, respiratory mask, detection kit, sanitary napkin, atopic eczema textile, disinfectant, knee guard, anti-microbial glove, food intolerance screening test, medical scrub, labcoat, wipe, analysis media, reagent kit, maternity cloth, barrier foot/ankle dressing, wristband, and so on. Restorative materials, toothpastes, adhesives, toothbrushes, composites, contra-angles, polishers, mouthwashes, burs, nanocoats, brushes, denture cleaners, luting cements, fissure sealants, bone substitute gels, layering ceramics, porcelain powders, toothbrush sterilizers, tongue cleaners, teeth whitening, carepastes, carepowders, multi primer pastes, bone substitute powders, and enamel matrix derivatives fall into the dentistry sub-industrial sector. The tissue engineering-related products contain scaffolds, antibodies, antiangiogenesis, medical hydrogels, hyaluronan fibers, topical bioadhesives, protein membrane immobilizers, human cells, and occluders. Implants, prosthesis, bioactive nanolayers, hydroxyapatites, and bone substitutes are the other products monitored.

Silver, titanium dioxide, silicon dioxide, zinc oxide, hydroxyapatite, and gold nanoparticles along with nanoclay and nanoliposomes are the most common nanostructures reported in the products, enabling or enhancing such properties as anti-bacterial activity, anti-microbial activity, deodorization, waterproofing, mechanical resistance, anti-fungal activity, breathability, biocompatibility, and anti-inflammatory.
