A foreign body reaction (FBR) is a typical tissue response to a foreign body within biological tissue. [1] It usually includes the formation of a foreign body granuloma . [ 2 ] Tissue encapsulation of an implant is an example, as is inflammation around a splinter . [ 3 ]
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.
A foreign-body giant cell is a collection of fused macrophages which are generated in response to the presence of a large foreign body. This is particularly evident with catheters , parasites , or biomaterials that are inserted into the body for replacement or regeneration of diseased or damaged tissues.
Host response is defined as the "response of the host organism (local and systemic) to the implanted material or device". Most materials will have a reaction when in contact with the human body. The success of a biomaterial relies on the host tissue's reaction with the foreign material.
Nano-cellulose presented at low concentrations produces a transparent gel material. This material can be used for biodegradable, homogeneous, dense films that are very useful in the biomedical field. [citation needed] Alginate: Alginate is the most copious marine natural polymer derived from brown seaweed. Alginate biopolymer applications range ...

The material becomes tightly stretched and the intestines may "accordion up" on themselves or be lacerated by it. This is especially common in cats who may enjoy playing with a ball of string or yarn. Sometimes the linear foreign body anchors in the mouth by catching under the tongue. [23] Pantyhose is a common linear foreign body in dogs.
[9] [24] In order for a biodegradable polymer to be used as a therapeutic, it must meet several criteria: 1) be non-toxic in order to eliminate foreign body response; 2) the time it takes for the polymer to degrade is proportional to the time required for therapy; 3) the products resulting from biodegredation are not cytotoxic and are readily ...
