e muneinadsorption to the surface of biomaterial is important? Explain the efle and changes of Gibbs free energy for protein adsorption (what the three efle how they alter the overall Gibbs free energy) 3+4 7 pts.) oinent and bioactive biomaterials in terms of interaction with surroun ion. Give one example for each. (8 pts.)

Solution

Protein adsorption:

Improper implantation or inappropriate adsorption of protein on the surface of biomaterials is leading to change in the conformation & protein conformation changed thereby “efficacy of the protein molecule” will be decreased followed by the formation of fibrous capsules, bacterial biofilms associated infections and blood clots. These are leading to adverse reactions. There it is crucial to ensure the proper surface adsorption has done on the surface of the biomaterials.

The Gibb’s free energy changes can be meticulously observed when a protein is adsorbed in vivo during a vascular grafting onto the polymer surface result in “sudden cardiac arrest” due to embolus formation may result in death. So that protein adsorption studies are essential on to the biomaterial. There will effective decreases in overall Gibbs free energy
