Compliant Surgical Adhesive
Surgical adhesives that include a blend of two different thermoreversible gelling polymers and a crosslinking agent are described. The first thermoreversible gelling polymer is partially or fully acrylated and the second thermoreversible gelling polymer includes dual functionality including acrylate functionality and amine-reactive functionality. The adhesives can provide gelling and covalent crosslinking within the polymers of the adhesive as well as crosslinking with surrounding tissue

Sensitive High Frequency AC Susceptometry in Magnetic Nanoparticle Applications
International audienceWe report on the development of a sensitive high frequency susceptometer capable of measuring in the frequency range from 25 kHz up to 10 MHz with a volume susceptibility sensitivity of 3.5×10−5 at 100 kHz corresponding to about 0.3% of the measured AC susceptibility. In combination with the previous reported DynoMag system capable of measuring dynamic magnetic properties in the range from 1 Hz to 200 kHz we are thus able to measure dynamic magnetic properties between 1 Hz to 10 MHz with high magnetic sensitivity. We will show AC susceptometry applications and results within the fields of magnetic hyperthermia and dynamic magnetic characterization of magnetic nanoparticle system with different particle sizes and magnetic properties
