Abstract
Lactoferrin is a highly safe antibacterial protein found in the human body and in foods. Calcium phosphate (CaP) nanoparticles with immobilized lactoferrin could therefore be useful as intraoral disinfectants for the prevention and treatment of dental infections because CaP is a mineral component of human teeth. In this study, we fabricated CaP nanoparticles with co-immobilized lactoferrin and heparin using a simple one-step coprecipitation process. Heparin, a negatively charged polysaccharide, was used as both an immobilizing agent for lactoferrin and a particle-dispersing agent. The immobilization efficiency for lactoferrin in the CaP nanoparticles depended on the concentrations of both the lactoferrin and heparin in the reaction solution and was over 90% under optimal conditions. The nanoparticles had a hydrodynamic diameter of about 150-200 nm and could be well dispersed in water, owing to their relatively large negative zeta potential derived from heparin. They were found to exhibit antibacterial activity against Actinomyces naeslundii, which is involved in the initial formation of dental plaque that consequently leads to dental caries and periodontal disease. These results indicate the potential of the proposed nanoparticles as intraoral disinfectants.

期刊介绍:
The International Journal of Molecular Sciences (ISSN 1422-0067) provides an advanced forum for chemistry, molecular physics (chemical physics and physical chemistry) and molecular biology. It publishes research articles, reviews, communications and short notes. Our aim is to encourage scientists to publish their theoretical and experimental results in as much detail as possible. Therefore, there is no restriction on the length of the papers or the number of electronics supplementary files. For articles with computational results, the full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material (including animated pictures, videos, interactive Excel sheets, software executables and others).
