About Chameleon Biosurfaces
Chameleon BioSurfaces is a provider of sophisticated surface design technology to medical device companies. Chameleon works closely with its customers to design and produce unique solutions to specific device challenges and opportunities.
We specialize in using electro-deposition to apply polymers to the surfaces of medical implants and devices to improve the functionality, performance and reliability of such systems. Our polymers can impart such features as lubricity, wettability, bio-compatibility and drug-elution. We can design surfaces so that drugs have a desired elution profile over time or are retained and presented at the device surface.
Also, we have unique patented technology to enable, for certain device configurations, on/off switching and extremely precise control of the amount, timing and location of drug release.
Chameleon's patented polymer deposition methods offer many manufacturing and process advantages. Polymers can be deposited in discrete patterns and gradients as well as uniformly over a device surface. Multiple polymer layers, each with a different functionality, allow highly sophisticated design features. Our electro-deposition methods ensure complete coverage even of complex and intricate surfaces, and also afford exquisite control of coating thickness, from sub-micron level upwards.
Chameleon's polymers are also available to design surface functionality in a wide range of technological applications, such as solid-state chemistry, microarray systems and sensors.
