Nanotechnology News

Breakthrough with artificial retinas for the visually impaired

Tel Aviv - Researchers have created a new light-sensitive film that could be the basis of a prosthetic retina. Such a retina could aid people suffering from retinal damage or degeneration.

Water treatment chemicals can upset the gut

Guelph - Scientists have shown that nanosilver, which is often added to water purification units, can upset the human gut. The research throws up some alarms on the level of nanoparticles that people are exposed to each day.

Nanoparticles used to monitor for cancer

Researchers have developed new nanoparticles that can be used for magnetic resonance imaging (MRI). This application could help medics to monitor a tumor’s environment and to assess if drugs have successfully reached their targets.

Nanorobots designed to swim through human blood

Bonn - Nanorobots could be designed to carry out medical tasks in the human body. Researchers have created “swimming bodies” that can navigate through biological fluids like blood.

Nanotechnology leads to improved retinal implants

Tel Aviv - Researchers have developed a new light-sensitive nanotube-based film. The technology could pave the way to more flexible and durable retinal implants.

How nanofibers can help prevent HIV / AIDS

Researchers have developed a special gel that is made up of a power virucidal chemical (to kill viruses) and a special nanofiber mesh. The device, designed to fit into a woman's body, can stop the transmission of the human immunodeficiency virus (HIV).

New bomb detector launched

Salt Lake City - A new type of bomb detector which uses a carbon nanotube has been produced. The detector is said to be superior to others on the market in terms of speed and the range of explosives that it can detect.

Implantable remote control drug dispersion device tested in space

Scientists are developing an implantable device that delivers therapeutic drugs as commanded by remote control. The device's effectiveness will be tested on animals aboard the International Space Station.

Nanotech lung infection device developed

Researchers have developed a low-cost, disposable breath analysis device for people with cystic fibrosis. The device sends data to a smartphone in the event of a lung infection.

Making nanoparticles shine

Scientists have successfully created nanoparticles that can emit a colorful fluorescent glow in a biological environment. The advantage is that the particles could be placed inside human cells to help to detect for a range of diseases.

Eye drops improved by nanotechnology

Scientists have developed a means to make eye drops more effective. The new method uses nanoparticles and it ensures that more of the active ingredient reaches the eye of the patient.

Nanotechnology helps contain Ebola

One problem affecting the containment of Ebola is the cost and complexity of diagnosing the disease when a patient is first seen. As a way forwards, researchers have developed a rapid, photonic device that can provide simple and accurate detection.

Nanoparticles used to solve crimes

Lausanne - Scientists have outlined a new method using nanoparticles to detect fingerprints left at crime scenes. The new technology is said to be far more accurate than the current process.

World’s smallest diamonds produced by nanotech

Scientists have found out how to produce ultra-thin "diamond nanothreads." These nano-diamonds have greater strength and stiffness compared with any other nanotubes and polymer fibers.

Nanoribbon film keeps glass ice-free

Scientists have created a nanoribbon that can keep glass free from ice. The material takes the form of a transparent coating, and it is based on graphene.

Japanese company announces space elevator to be completed by 2050

Tokyo - Although it may sound like something from a Hollywood science fiction movie, engineers at a prominent Japanese construction company are serious about building the world's first working space elevator.

New nanopatch can be used against polio

A new nanopatch has been developed as a candidate method for the delivery of a polio vaccine. The patch thereby avoids the use of a needle.

Cancer fighting nanoparticles in development

Researchers have created "dynamic" nanoparticles that could provide an array of applications to diagnose and treat cancer. The nanoparticles have been made from a polymer, and they are designed to seek out and to identify tumors.

Nanotechnology helps immune cells fight cancer

Scientists have developed a novel cancer immunotherapy. This involves growing and enhancing a patient’s immune cells using a nanotube and then injecting them back into the patient’s body to boost their immune response.

Is gold nanotechnology the key to fighting Ebola?

As the World Health Organization holds crisis meetings to discuss ways to battle the Ebola outbreak, one scientist thinks that one solution for fighting the deadly virus is nanotechnology.

New cling-wrap treatment for burns

Novel, ultrathin coatings called nanosheets have been produced to protect burns from bacterial infections. The sheets cling to the body’s most difficult-to-protect contours and prevent infection.

Nanoparticles may be 'alarm clock' body needs to fight cancer

Lebanon - Researches looking for ways to jump start the immune system so it can recognize and attack cancer cells believe nanoparticles may be the "alarm clock" our body needs to fight cancer.

Using ‘nanojuice’ to examine the gut

Scientists are developing a new imaging technique involving nanoparticles suspended in liquid to form “nanojuice” that patients would drink.

Scientists find a way to ‘tune’ graphene

Researchers continue to work on the wonder material of the age: graphene. Part of this involves ‘fine tuning’ the material in preparation to make a new generation of ‘superconductors’.

Gold nanoparticles target breast cancer

Researchers have developed a way to detect and measure cancer levels in a living cell by using tiny gold particles with tails of synthetic DNA.

Silver nanoparticles target tumors

Scientists at have designed a nanoparticle that is spherical in shape and silver in composition. These nanoparticles help to locate and visualize tumor cells.

'Nanobubble' technology announced for cancer patients

Studies at Rice University have tested a new method for treating cancer using what they call a "plasmonic nanobubble" in their literature. These allegedly can severely damage the cancer cells then release a payload of antibodies to kill the cancer.

Nanotech creates super batteries

Miami - Scientists have developed a way to both transmit and store electricity in a single lightweight copper wire. By being able to store and conduct energy on the same wire, heavy, space-consuming batteries could become a thing of the past.

Graphene is composed of nano fibers

Researchers studying graphene’s properties have used a new mathematical framework to make extremely accurate characterizations of the two-dimensional material’s shape. They have concluded the material is composed of nano-fibers.

What can nanomedicine deliver?

Only a few nanotherapeutics are currently on the market. However, dozens more are making their way through preclinical studies and clinical trials. What is special about this medical development?
