Query: Studies of protein adsorption on implant materials in relation to
  biofilm formation I. Activity of Pseudomonas aeruginosa on Polypropylene and
  High density Polyethylene in presence of serum albumin   The surface of biomaterials used as implants are highly susceptible to
bacterial colonization and subsequent infection. The amount of protein
adsorption on biomaterials, among other factors, can affect the nature and
quality of biofilms formed on them. The variation in the adsorption time of the
protein on the biomaterial surface produces a phenotypic change in the bacteria
by alteration of the production of EPS (exoplysaccharide) matrix. Knowledge of
the effects of protein adsorption on implant infection will be very useful in
understanding the chemistry of the biomaterial surfaces, which can deter the
formation of biofilms. It is observed that the adsorption of BSA on the
biomaterial surfaces increases with time and concentration, irrespective of
their type and the nature of the EPS matrix of the bacterial biofilm is
dependent on the amount of protein adsorbed on the biomaterial surface. The
adsorption of protein (BSA) on the biomaterials, polypropylene (PP) and high
density polyethylene (HDPE) has been studied and the formation of the biofilms
of Pseudomonas aeruginosa on them has been examined.
