Is technological progress slowing down? Are we simply refining technological advances originally made in the 1980s or earlier? Fear not: there is a next wave that will revolutionize technology. And it's small. Real small. A look at nanotechnology.
Nanotechnology is being used in a number of areas. In medicine, there have been advances in using nanoparticles to fight cancer. One problem is stopping the nanoparticles killing other cells. For this, a new solution has been found.
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.
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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
