Prevention of Protein Adsorption and/or Bacterial Propagation on the Surface of a Medical Device

NineSigma, representing a global manufacturer, seeks technologies that can prevent protein adsorption and/or bacterial propagation on the surface of a medical device that comes in contact with internal parts of the human body. The Client expects to receive a wide range of proposals, including surface coatings and treatment of the device, as well as technologies related to materials that achieve the expected function in combination with a component of the device surface.

Overview

Details of medical device that comes in contact with internal parts of the body

  • Material:
