Over three million Australians suffer from hearing loss but fewer than 20% of them use hearing aids. Part of the problem is that technology just isn't good enough for them. Researchers from Sydney are changing that. They've developed a more eff
Ophthalmologists at Rush University Medical Center implanted Artificial Silicon Retina (ASR) microchips in the eyes of five patients to treat vision loss caused by retinitis pigmentosa (RP). The implant
A new camera-in-a-pill can help doctors diagnose and evaluate diseases of the esophagus including gastroesophageal reflux disease (GERD), erosive esophagitis and Barrett's esophagus (a pre-cancerous condition) without the use of a traditional endoscope
Researchers from the University of Southern California and the Doheny Eye Institute will be presenting data on the first six patients implanted w
One key goal of treating pancreatic cancer, which is often fatal within a year, is making sure patients have a good quality of life with as few complications as possible. This is especially important if they are candidates for surgical removal of the c
The world's smallest computer (around a trillion can fit in a drop of water) might one day go on record again as the tiniest medical kit. Made entirely of biological molecules, this computer was successfully programmed to identify - in a test tube - change

Coating characterisation of polymer-coated cardiovascular stents has been undertaken utilising ToFSIMS, DSIMS and 3DP.Time-of-Flight Secondary Ion Mass Spectrometry (ToFSIMS) provides detailed molecular information from the very outer surface of a stent to investigate the molecular make-up of the contact point between stent and host.
Contamination on the surface of stents can also be investigated by ToFSIMS providing spectra and images of the surface i.e. what is the chemistry and where is it lying?
Figure 1-ToFSIMS Image showing contamination on a medical deviceDynamic Secondary Ion Mass Spectrometry (DSIMS) depth profiles monitor the active pharmaceutical ingredient as a function of depth and are repeated at set intervals through the elution studies to determine the rate of elution. Valuable information about the elution rate and state of the active pharmaceutical ingredient can be gained.
Figure 2-Representative DSIMS depth profile3D Non-Contact Profiling (3DP), a white light interferometry technique, has been utilised to determine the uniformity and roughness of the polymer coating. The interference patterns are interpreted to produce linescans, 2D and 3D images of the surface form which roughness, peak height and valley depth can be determined.
