Nanomedicine

New technology could allow vaccines to be produced when and where they're needed (Photo: S...

Researchers from the University of Washington have created a vaccine with the potential to make on-demand vaccination cheaper and quicker, using engineered nanoparticles. Tests with mice show definite promise for the technology's use on humans.  Read More

A close look at one of the nanomotors (inset), inside a living human cell

Imagine if it were possible to send tiny machines into living cells, where they could deliver medication, perform ultra-micro surgery, or even destroy the cell if needed. Well, we've recently come a little closer to being able to do so. Scientists at Pennsylvania State University have successfully inserted "nanomotors" into human cells, then remotely controlled those motors within the cells.  Read More

There may be new hope for heart attack victims, in the form of patches that incorporate go...

When someone has a heart attack, the damaged heart tissue doesn’t grow back. Instead, it’s replaced by non-beating scar tissue. As a result, the heart is permanently weakened. Now, however, researchers at Tel Aviv University are getting promising results using patches that contain cardiac cells and gold nanofibers.  Read More

For several years now, scientists have been exploring the use of patches of arrayed microneedles as a means of “injecting” medication through the skin. Researchers at North Carolina State University are now working on something similar, but at a much smaller scale – they're developing tiny needle-covered balloons, to deliver medication to individual cells.  Read More

UB researchers have studied the effects of quantum dots in primates - the clusters seen he...

Nanomedicine is a hugely promising field, but while remarkable new treatments and diagnostic tests are being developed, questions remain about the long term effects of nanoparticles on our bodies. Adding to our understanding of these issues, researchers have now reported that the use of quantum dots - tiny luminescent crystals that can be used to monitor disease at a cellular level - appears to be safe in primates over a one-year period.  Read More

A drop of liquid sits on the textured silicon surface that has arced rungs to guide the dr...

Lately we’re hearing more and more about tiny medical and environmental diagnostic devices, that can perform a variety of tests using very small fluid samples. Working with such small samples does present a challenge, however – how do you thoroughly mix tiny amounts of different fluids, or wrangle individual drops for analysis? According to a team of scientists from the University of Washington, the answer lies in the lotus leaf.  Read More

The nanobubbles are short-lived events that expand and burst, thus creating a small hole i...

U.S. researchers are developing a promising new approach to the targeting of individual cancer cells. The technique uses light-harvesting nanoparticles to convert laser energy into “plasmonic nanobubbles,” enabling drugs to be injected directly into the cancer cells through small holes created in the surface. Researchers claim that the delivery of chemotherapy drugs in this way is up to 30 times more effective on cancer cells than traditional drug treatments and requires less than one-tenth the clinical dose.  Read More

The programmable DNA nanorobot developed by Wyss Institute researchers is shaped like a ba...

We've seen various experimental approaches that aim to increase the efficacy of chemotherapy while also reducing its damaging side effects by specifically targeting cancer cells. The latest encouraging development comes from Harvard's Wyss Institute for Biologically Inspired Engineering where researchers have created a barrel-like robotic device made from DNA that could carry molecular instructions into specific cells and tell them to self-destruct. Because the DNA-based device could be programmed to target a variety of cells, it could be used to treat a range of diseases in addition to providing hope in the fight against cancer.  Read More

Prototype of Purdue's new rap music-powered implantable pressure sensor

We've been following the evolution of patient-embedded medical sensors for some time - miniature devices that run on batteries, transcutaneous (through-the-skin) induced current, even sugar and provide constant monitoring of various metabolic parameters. Now, a team from Purdue University's Birck Nanotechnology Center has developed a prototype pressure sensor which promises to address the shortcomings of previous designs and utilizes a novel power supply: the acoustic energy from bass-heavy riffs of rap music.  Read More

Optical microscope picture of an antenna structure with nano-antennas built into its cente...

We recently looked at one of the potential contenders in the US$10 million Qualcomm Tricorder X PRIZE, which as the name suggests, was inspired by the medical tricorder of Star Trek fame. Now scientists have developed a new way of creating Terahertz (THz) or T-rays, which they say could help make handheld devices with tricorder-like capabilities a reality.  Read More
