An implant like a hip-stem replacement necessitates integration with the host tissues, and protein adsorption facilitates this integration. Surgical tools can be designed to be sterilized more easily so that proteins do not remain adsorbed to a surface, risking cross-contamination.
Protein patterning – chessboard pattern. Biomaterials are materials that are used in contact with biological systems. Biocompatibility and applicability of surface modification with current uses of metallic, polymeric and ceramic biomaterials allow alteration of properties to enhance performance in a biological environment while retaining bulk properties of the desired device.
Protein adsorption influences the interactions that occur at the tissue-implant interface. Protein adsorption can lead to blood clots, the foreign-body response and ultimately the degradation of the device. In order to counter-act the effects of protein adsorption, implants are often coated with a polymer coating to decrease protein adsorption.
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
The bone cement fills the free space between the prosthesis and the bone and plays the important role of an elastic zone. This is necessary because the human hip is acted on by approximately 10–12 times the body weight and therefore the bone cement must absorb the forces acting on the hips to ensure that the artificial implant remains in ...
An implant is a medical device manufactured to replace a missing biological structure, support a damaged biological structure, or enhance an existing biological structure. For example, an implant may be a rod, used to strengthen weak bones. Medical implants are human-made devices, in contrast to a transplant, which is a transplanted biomedical ...
Technique depicted in 3D video This image shows how Nobel Biocare's All-on-4 solution works. The term All-on-4, also known as All-on-Four [1] and All-in-Four, [2] refers to 'all' teeth being supported 'on four' dental implants, a prosthodontics procedure [3] [4] for total rehabilitation of the edentulous (toothless) patient, or for patients with badly broken down teeth, decayed teeth, or ...
Affinity chromatography can be used in a number of applications, including nucleic acid purification, protein purification [9] from cell free extracts, and purification from blood. By using affinity chromatography, one can separate proteins that bind to a certain fragment from proteins that do not bind that specific fragment. [ 10 ]
