Micro-and Nano-Fibers in Biomedical Application

Advancements in biomedical micro/nano tools and technology.

Emerging Biomedical Technologies at the Micro and Nano Levels

ADVANCES IN LIFE SCIENCE RESEARCH Throughout the history of medicine, many advances have been driven by important technological innovations. For example, the invention of the X-ray machine, more than a century ago, revolutionized medicine and pioneered the use of noninvasive imaging in the diagnosis and detection of diseases. The invention of the microscope essentially redefined the fields of p...

Fabrication of PGS/CaTiO3 Nano-Composite for Biomedical Application

Biodegradable elastomeric materials are gaining extensive attention in the field of soft tissue engineering. Poly (glycerol sebacate) (PGS) is a novel biocompatible elastomer in this scope. However this polymer has poor mechanical properties especially when the molar ratio of glycerol is higher than sebacic acid. Calcium Titanate (CaTiO3) is a biocompatible ceramic with some degr...

Evanescent-wave photoacoustic spectroscopy with optical micro/nano fibers.

We demonstrate gas detection based on evanescent-wave photoacoustic (PA) spectroscopy with tapered optical fibers. Evanescent-field instead of open-path absorption is exploited for PA generation, and a quartz tuning fork is used for PA detection. A tapered optical fiber with a diameter down to the wavelength scale demonstrates detection sensitivity similar to an open-path system but with the ad...

Tin oxide micro/nano fibers from electrostatic deposition

SnO2 micro/nano fibers in the rutile structure were synthesized using electrospinning and metallorganic decomposition techniques. Fibers were electrospun using two different precursor solutions, one based on SnCl4 and the other on C22H44O4Sn. The fibers were sintered in air for two hours at 400, 500, 600, 700 and 800oC. SEM, AFM, XRD, XPS and Raman microspectrometry were used to characterize th...
