Nanotechnology products are used in medical & Health care in many ways. For example home pregnancy test uses gold nanoparticles ofless than 50 nanometers in diameter. If HcG is detected nanoparticles reflect red, otherwise blue.Nano Mask utilises nanoparticle enhanced filters to block potentially harmful airborneContaminants. Further it attacks contaminants in both inhaled and exhaled airNanosilver Wound Dressings of patented nanocrystalline technology uses silver Nanoparticles which give powerful antimicrobial barrier protectionIn the formulation of joint and muscle pain cream Nanotechnology helps to deliver active ingredients of 90 nanometer liposomes to soothe aching muscles through skin. Liposomes are small, spherical vesicles which consist of amphiphilic lipids, enclosing an aqueous core.Nanotechnology in dental care makes use of dental adhesives using silica Nanofiller Technology gives stronger bond to tooth enamel. Cavity Preventing Toothpaste is made using fluoride compounds which turn into 10nm calcium fluoride particles in the mouth so that teeth absorbs the cavity-preventing fluoride.In beauty care nanotechnology based face creams by L’Oreal Paris uses a patented 200nm vitamin A inside a polymer capsule where outer shell dissolves under the skin. Also Zelens incorporates nanoscale Fullerene C-60 with remarkable antioxidant properties.As sunscreen Lotion particles having smaller than wavelength of light which are photostable UV absorbers made of ultra-fine titanium dioxide / zinc oxide are used.As hair colour defender to prevent sunlight from attacking hair colour and to guard against colour-fading UVA/UVB rays and has antioxidant properties are used. Moist Soft Cloth Mask which uses Bamboo-Carbon Nanoparticles absorbs far infra-red radiations and are antibacterial, Antifungal and Deodorant. Hair Shampoo uses Nanotechnology to penetrate hair shaft with the target areas where hair repair is needed.
