✦ Synopsis

Abstract

Calcium phosphate nanoparticles were functionalized using two polymeric additives: polyallylamine hydrochloride, PAH, giving them a positive charge, and polyacrylic acid, PAA, giving them a negative charge. These particles were deposited on surface‐functionalized polymers (polyethylene terephthalate track‐etch membranes; PET) by dip‐coating. If the charge of the nanoparticles and the charge of the polymer membrane had an opposite sign, efficient adsorption was observed, whereas on unfunctionalized polymer surfaces, no adsorption occurred.

## Abstract Calcium phosphate nanoparticles were prepared by precipitation from aqueous solution. A stable colloid was formed by coating with DNA. The properties of the colloidal dispersion can be adjusted by variation of the inorganic nanoparticles. In particular, the partial substitution of calci

Titanium implants are known to nucleate spontaneously a calcium phosphate (apatite-like) layer when in contact with biological model fluids. The presence of proteins either in solution or pre-adsorbed on the titanium surface may influence the process of calcium phosphate deposition. The role of fibr

## Abstract We have recently shown that a new implant surface design, achieved by the deposition of discrete nanocrystals of calcium phosphate on microtopographically complex titanium‐based substrates, accelerates osteoconduction and also renders the implant surface bone bonding. Thus, we wished to
