Correlation between fatigue crack growth and acoustic emission in pyrolytic carbon provides a basis for quality assurance in mechanical heart valves.




An atomic force microscope image shows the surface structure of a hydrated Staphlococcus epidermis biofilm formed on an implant surface. The channels observed are believed to provide nourishment that sustains the biomaterials-associated infection.
