I was reading a press release from IBM about a technique called Magnetic Resonnance Force Microscopy(MRFM). Through this technique, one could acheive magnetic resonance imaging (MRI) with a volume resolution 100 million times finer than conventional MRI which is really impressive. Moreover, the technique could be extremely usefull for 3D imaging of small viruses or proteins. The image shows the set up of the apparatus.
The magnetic resonance force microscope (MRFM) is a novel scanned probe instrument which combines the three-dimensional imaging capabilities of magnetic resonance imaging with the high sensitivity and resolution of atomic force microscopy. It will enable non-destructive, chemical-specific, high-resolution microscopic studies and imaging of subsurface properties of a broad range of materials. This technology holds clear potential for atomic-scale resolution.( reference)
Here is a recent journal article published in ' proceedings of the national academy of sciences' where you can find more detailed and scientific explanations about the technique:
Degen et al., ''nanoscale magnetic resonance imaging'', the article is in the presse( published already online),
There is a video on youtube that explains simply how the system works:

University of North Carolina (UNC) and Harvard scientists have recently teamed up to develop an inhaled tuberculosis vaccine. This vaccine is a godsend for developing countries, as it won't require refrigeration and medical-grade water like the typical vaccine.
Professor Tony Hickey, who teaches at the
This new inhalant was created by taking the regular tuberculosis vaccine and changing it into fine powder. Experts from both UNC and Harvard collaborated on this project in the laboratory of David Edwards. Edwards is a professor of biomedical engineering at Harvard. The development of the new vaccine was made possible by a grant from the Bill and Melinda Gates Foundation.
Though the inhalant has yet to be tested on human subjects, guinea pigs have responded well thus far. Scientists have administered the drug to the animals, then exposed them to tuberculosis. Not only did the vaccine work well, it appeared to be even more effective than the regular vaccine injections.
The new vaccine will be administered with a plastic tube, which is reportedly similar to a drinking straw. The inhalant is taken orally, which can pose problems with young children. To combat this issue, a special pacifier may be designed for babies to that the inhalant will be blown into the back of their mouths.
The next step to getting the drug on the market is to begin human clinical trials. Hopefully, the vaccination could be used in

Use of wireless systems in medical devices brings in most of cases more comfort and less damage to the patient. As an example one can name the Bravo pH monitoring system of Medtronics.
The catheter-free Bravo pH Monitoring System is a pH testing with a capsule that collects pH data and transmits it via radio frequency telemetry to a small external pager-sized receiver worn by the patient.
The ambulatory pH test has long been referred to as the "gold standard" for diagnosing reflux disease. This test provides information about the duration, pattern and symptom correlation of distal esophageal acid exposure from gastro-esophageal reflux(GER).
compared to conventional methods associated with using catheter pH systems, this method:
- Allows patients to maintain regular diet and activities
- Minimizes throat and nasal discomfort
- Allows physicians to extend pH data collection to 48 hours — 24 hours beyond the recording capability of conventional catheter systems

Collagen is one the important load-bearing components in the body and the collagen structure has a distinct role in mechanical properties of the tissue. One of the challenges today is to visualize the collagen structure in live tissues or fresh tissues without fixing the tissue. It's clear that fixing methods are invasive and may alter the tissue structure. As an example, in tissue engineering experiments, visualization of changes in collagen three dimensional structure is essential for the understanding of collagen fibrils formation and remodeling.
Fluorescent CNA35 collagen probe developed in the laboratory of macromolecular and organic chemistry, Eindhoven University of Technology, The Netherlands, shows much specificity to collagen compared to other existing fluorescent techniques currently used for collagen visualization in live tissues and shows improved details compared to SHG ( second harmonic generation microscopy). However, in my opinion, the tissue should be relatively thin to let the prob perfuse all over the tissue.
The figure shows a mouse carotid artery, (Up) SHG signal of collagen (green), (down) fluorescence signal of collagen probe (green, CNA35-OG488) in a mouse carotid artery recorded at the same focal position obtained with two-photon laser scanning microscopy (15 μm deep)
