Use of Nanoparticle in Temperature Sensitive Liposomal Drug
Delivery

Liposomes are nonimmunogenic, biodegradable
and non toxic in nature hence they are used as drug delivery vehicles.
Liposome surfaces are highly flexible and can be made target specific.
The main emphases of the current talk is i) fabrication of temperature
sensitive and nontoxic nanoparticles for embedding with PEG iii) coating
of PEG for liposome stabilization along with nanoparticles iv) encapsulation
of drug in liposomes v) biophysical characterization of liposomes
vi) determination of drug encapsulation efficiency of liposomes. The
sterically stable/ stealth liposomes were prepared by attaching Polyethylene
glycol (PEG) and nanoparticles on the liposome surface. Addition of
cholesterol and nanoparticles was just not to affect flexibility and
fluidity. Albendazole and methotrexate as drugs were used for encapsulation
and release. The drug encapsulation capacity and release sensitivity
of liposomes was studied by dialysis method. The biophysical characterization
of both PEG and nanoparticle coated and uncoated liposomes were done
by TEM and UV-Spectroscopy.
