Researchers to develop ultra-miniature implantable sensors to measure blood flow

...egrated with present tools." Kan noted that these miniature sensors can be as small as 100 microns in length b...al monitoring. Transonic Systems already produces miniature devices for measuring blood flow in physiology and pharmacology studies. According to Transonic proj...

Nanosecond-scale release of stinging jellyfish nematocysts

...ing cells used for prey capture and defense. These miniature cellular weapons contain a cocktail of hemolytic and neurotoxic poisons, making some cnidarians the most venomous animals known. Injection of the toxins requires an effective release mechanism that breaks the physical barrier of the prey's outer-surf...

Five new technologies that promise to transform medicine

Fat zapping to shed excess weight, miniature telescopes to restore vision, and smart nappies to...es who need regular medication will benefit from a miniature implant that monitors and transmits data on heart and breathing rates, blood pressure, and blood sug...

Three-dimensional, miniature endoscope opens new diagnostic possibilities

Cardiologist's 'living chip' changes science of disease monitoring

... engineered to live on and function as part of the miniature electronic chip. The wireless biosensor is placed within and around blood vessels and nerves to provide detection and stimulation of the surrounding tissues or organ systems, with the ability to detect changes. A change triggers a message to a wirele...

Biofuel cells without the bio cells

...le from the organisms that spawned them could make miniature bioreactor cells feasible. "We show that you can directly transfer electrons to a mineral using a purified protein, and I don't think anyone had shown that before," said Thomas Squier, senior author and lab fellow at the Department of Energy's Paci...

MIT designs portable 'lab on a chip'

...have taken a major step towards making an existing miniature "lab on a chip" fully portable, so the tiny device...led to a revolution in computing, the idea is that miniature laboratories of fluid being pumped from one channel to another, with reactions going on here and the...

Nano-devices hold promise for early-stage cancer detection

They are miniature labs that can be swallowed like a pill, injected t...s. Research currently underway includes: a miniature (pill-sized) device that will provide early detection of abnormal cells inside the body; an imagi...

New sensor detects gaseous chemical weapon surrogates in 45 seconds

...ch in turn creates a very small acoustic signal. A miniature quartz tuning fork acts as a "microphone" to record the resulting sound wave. PNNL researchers paired multiple QCLs with the tuning forks, allowing simultaneous examination of a single sample at many infrared wavelengths. Nearly every molecule has...

Einstein's tea leaves inspire new blood separation technique

...ral inward toward the bottom of the chamber like a miniature tornado, leaving a clear layer of plasma above. Yeo anticipates the technology could be incorporated into a chip roughly the size of a credit card. He said the devices could be produced cheaply with current manufacturing techniques -- about 50 cent...

Researchers demonstrate way to control tree height

...ght of trees, showing that it’s possible to create miniature trees that look similar to normal trees – but after several years of growth may range anywhere from 50 feet tall to a few inches. This is a “proof of concept” that tree height can be readily controlled by genetic engineering techniques. It opens the...
