Currently,
nanosized materials are extensively used in design of the optical devices,
catalysts, biosensors, imaging agent, drugs and gene delivery, etc. There are alarge number of nanoparticles including gold nanoparticles, polymeric
nanoparticles, quantum dots, bioceramic based nanoparticles and so on that are
applied as carriers in the drug delivery systems. Definitely, dominant
physicochemical properties of these materials such as small size and high
surface to volume ratio lead to improvement of their effectiveness as a
suitable carrier in drug and gene delivery.
In the recent decades, the
production of bioceramics with nanostructures has attracted much attention for
biomedical applications. Among various types of bioceramics, hydroxyapatite
(HAp) is one of the attractive bioceramics which is widely used in various
fields of science such as tissue engineering, drug delivery systems and
chromatographic purification
