Nanotechnology News

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?

Experts create intelligent 'plaster' to monitor patients

Paris - Medical engineers said Sunday they had created a device the size of a plaster which can monitor patients by tracking their muscle activity before administering their medication.

‘Iron Man’ super-plant made using nanotech

A team of MIT researchers wants to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production.

Super chip provides real-time images of the heart

Scientists have developed a catheter-based device that can provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries, and peripheral blood vessels.

Nanoparticles treat muscular dystrophy

Researchers have demonstrated a new approach to treating muscular dystrophy. In studies using mice, the rodents showed improved strength and heart function when treated with nanoparticles.

Taking photos in near darkness, thanks to nano tech

Scientists have discovered that a special super-thin layer of nanomaterial could dramatically improve how cameras work, especially in circumstances when there is not much light.

Imaging technology helps screen childhood disease

Respiratory syncytial virus (RSV) can cause serious illnesses in children. In the early stages the disease is difficult to detect. New imaging technology offers a way to increase detection of the disease.

Nanotechnology could fight influenza

Researchers are developing an advanced type of nanotechnology that “traps” viruses before they can infect host cells. This is designed to reduce the rate of flu infections.
