New Drug-releasing Coating for Implants

12.09.2012
</a><strong>Background</strong><br>

When repairing a missing, broken or diseased portion of bone, implants are being used fabricated from a variety of materials including metal, polymer and ceramics. To improve the property of implants, a porous coating is typi-cally applied onto the surface to foster long term stabilization. To promote healing, drug substances having e.g. antibiotic, cytostatic and/or osteogenic properties can be coated to the surface of the implant. <br><br> As metal implants are not easily modified to comprise a drug release mecha-nism, the implant coats have been suggested to serve as drug carrier. How-ever, these coatings fail as they are often too mechanically unstable during implant fixation. Furthermore, as the location of the drug on the surface of the implant is determined during the pre-coating process, the pre-coated implants do not allow customization, and loading of the drugs to be delivered. <br><br> <strong>Technology</strong><br>

We offer a new elastic biocompatible drug-releasing patch for applica-tion/coating on implants. The drug-delivery patch can be customized in shape, size, and drug loading for optimal local delivery before implantation and applied directly at the operating room.<br><br> <b>Benefits:</b><ul> <li>The coating can be customized specifically for each patient. The customized coating can contain unique drug/dosage combinations specifically for individual patients.</li> <li>Compared to pre-coated prior art implants the new coating provides several advantages including flexibility, ease of use, and point-of care individualization of implants.</li></ul> <p><strong>IP Rights</strong><br> EP application filed 12/2007<br> US application filed 12/2008 <br><br> <strong>Patent Owner</strong><br> Charité – Universitätsmedizin Berlin

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

So-called pre-distorted states accelerate photochemical reactions too

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
