Controlling the Formation of Hydroxyapatite Nanorods with Dendrimers
TL;DR: A facile procedure to direct the formation of hydroxyapatite (HAP) in preference to all other calcium phosphate phases and control over nanoparticle size distribution and morphology, with potential application in biomedical implants, is reported in this paper.

TL;DR: The results of this study suggest that 75/25 w/w nHAp/CS scaffolds should be considered as a suitable biomaterial for GBR.
A novel hybrid sol–gel method for the synthesis of highly porous silica employing hyperbranched poly(ethyleneimine) as a reactive template
TL;DR: In this article, a hybrid sol-gel templating route employing hyperbranched polymers for the production of nanostructured silica with tailored porosity and high specific surface area values is proposed based on the use of hyperbranched poly(ethyleneimine) both as a reactive template and as a macromolecular "porogen".

TL;DR: In this paper, the biological effect of 75/25 w/w nano-hydroxyapatite/chitosan (nHAp/CS) scaffolds on bone regeneration, in terms of fraction of bone regeneration (FBR), total number of osteocytes (Ost), and osteocyte cell density (CD), as well as its biodegradability.
Biomimetic synthesis of ribbon-like hydroxyapatite employing poly(l-arginine)
TL;DR: It was found that the presence of PA promotes HAP formation and affects its crystal size and morphology possibly through a rather specific interaction between the homopeptide that is positively charged and also that adopts a β-sheet conformation and the negatively charged c-plane of the growing HAP crystal.
