Clothes Embedded With Nanoparticles Heal The Skin

Tiny capsules embedded in the clothes we wear could soon be used to counteract the rise of sensitive skin conditions.

As people are getting older, they have more sensitive skin, so there is a need to develop new products for skin treatment,” says Dr Carla Silva, from the Centre for Nanotechnology and Smart Materials (CENTI), in Portugal

This increased sensitivity can lead to painful bacterial infections such as dermatitis, otherwise known as eczema. Current treatments use silver-based or synthetic antibacterial elements, but these can create environmentally harmful waste and may have negative side effects.

To combat these bacterial infections in an eco-friendly way the EU-funded SKHINCAPS project is combining concentrated plant oil with nanotechnology. Their solution puts these so-called essential oils into tiny capsules that are hundreds of times smaller than the width of a human hair. Each one is programmed to release its payload only in the presence of the bacteria that cause the skin infections. This means that each capsule is in direct contact with the affected skin as soon as an infection occurs, increasing the effectiveness of the treatment.

According to Dr Silva, who is also project coordinator of SKHINCAPS, the nano-capsules are attached to the clothing material using covalent bonding, the strongest chemical bond found in nature. This ensures the capsules survive the washing machine and that they are invisible to whoever is wearing them. This nanotechnology has a lifespan equal to that of the garment, though the active ingredients contained in the nano-capsules will run out earlier depending on the extent of the skin infection, and thereby on how much of the treatment is released when the clothing is worn.

The nano-capsules will prove invaluable for chronic eczema sufferers and those with high levels of stress, as well as the elderly and diabetics, who are particularly vulnerable to developing such infections.

SMILE!

A brighter, better, longer-lasting dental implant may soon be on its way to your dentist’s office. Dental implants are posts, usually made of titanium, that are surgically placed into the jawbone and topped with artificial teeth. More than dentures or bridges, implants mimic the look and feel of natural teeth. While most dental implants are successful, a small percentage fail and either fall out or must be removed. A scientist at Michigan Technological University wants to lower that rate to zero using nanotechnology.

“Dental implants can greatly improve the lives of people who need them,” said Tolou Shokuhfar, an assistant professor of mechanical engineering. “But there are two main issues that concern dentists: infection and separation from the bone.

The mouth is a dirty place, so bacterial infections are a risk after implant surgery, and sometimes bone fails to heal securely around the device. Because jawbones are somewhat thin and delicate, replacing a failed implant can be difficult, not to mention expensive. Generally, dentists charge between $2,000 and $4,000 to install a single implant, and the procedure is rarely covered by insurance. Enter a nano-material that can battle infection, improve healing, and help dental implants last a lifetime: titanium dioxide nanotubes.
