CD44 tagged hyaluronic acid - chitosan liposome carrier for the delivery of berberine and doxorubicin into lung cancer cells.

Liposomes are unique biomolecular, capable of loading both hydrophilic and hydrophobic molecules and delivered into the biological system. Liposomes (L) coated with hyaluronic acid (HA) and chitosan (CS) carrier system was fabricated. Berberine (BER) and doxorubicin (DOX) were encapsulated to enhance drug proliferation and therapeutic effect in lung cancer cells.

In-vivo assessment of minerals substituted hydroxyapatite / poly sorbitol sebacate glutamate (PSSG) composite coating on titanium metal implant for orthopedic implantation.

Currently, bio-mimetic material synthetic processes are involved in bone implant design which is closely related to natural bone. In this work, Zinc, Cerium and Selenium substituted hydroxyapatite/ Poly (sorbitol sebacate glutamate) (Zn, Ce, Se-HAP/PSSG, M-HAP/PSSG) composite was prepared by sol-gel method as a bio-mimetic materials for bone implantation. The physiochemical characterizations of M-HAP/PSSG was analyzed by Fourier transform infra red (FT-IR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) equipped with energy dispersive X-ray analysis (EDX) and High resolution transmission electron microscopy (HRTEM).

Fabrication of bioactive rifampicin loaded κ-Car-MA-INH/Nano hydroxyapatite composite for tuberculosis osteomyelitis infected tissue regeneration.

Biocompatible polymers and ceramic materials have been identified as vital components to fabricate drug delivery and tissue engineering applications because of their high drug loading capability, sustained release and higher mechanical strength with remarkable in-vivo bioavailability. In the present work, initially we designed κ-carrageenan grafted with maleic anhydride and then reacted it with isoniazid drug (κ-Car-MA-INH). The polymeric system was cross linked with nanohydroxyapatite (NHAP) via electrostatic interaction followed by the addition of rifampicin (RF) and loaded to fabricate κ -Car-MA-INH/NHAP/RF nanocomposites.

Stimulus-responsive zinc oxide-functionalized macromolecular humic acid nanocarrier for enhancement of antibacterial activity of ciprofloxacin hydrochloride.

Macromolecular of naturally occurring humic acid (HA) have garnered interest in the chemical, biological and medicine industry owing to their unique behavior, i.e., strong adsorptive and non-toxic nature.
