Abstract In this work, first, copper oxide nanoparticles (CUO NPs) were synthesized by physical methods and then coated with the bovine serum albumin (BSA) via biologically meditated minerals to form CUO@BSA NPs. Finally, curcumin (CUR) as an anticancer drug were immobilized on the surface of CUO@BSA NPS. The properties of CUO@BSA-CUR NPS were investigated by FTIR, UV-Vis, TEM, and AFM spectroscopes. It was found that the synthesized CUO@BSA-CUR nanoparticles were spherical with a particle size of 20 to 30 nm and have a sustained release of CUR at 37°C in buffer solution. Also, the result of release in biological environment showed that maximum drug release rate for this nanocarrier in pH 7.4 was measured 75% after 48 hours. The cytotoxicity of CUO@BSA-CUR on MDA-MB-231 cell line was studied. The results showed that CUO@BSA-CUR nanoparticles have significant cytotoxic activity on this cell line, while the results of MTT assay indicated the CUO@BSA NPs have no toxicity effect on the cancer cells.

This study involves the synthesis of hydroxyapatite and describes the preparation and characterization of polymer coatings based on poly(ethylene glycol) diacrylate and poly(ethylene glycol) and modified with bovine serum albumin and hydroxyapatite. Hydroxyapatite was obtained by wet chemical synthesis and characterized by X-ray diffraction and FTIR spectroscopy, and its Ca/P molar ratio was determined (1.69 ± 0.08). The ceramic and bovine serum albumin were used in the preparation of composite materials with the polymeric matrix. The chemical composition of coatings was characterized with FTIR spectroscopy, and their morphology was recorded with SEM imaging. Moreover, the measurements of surface roughness parameters and stereometric research were performed. The prepared coatings were subjected to in vitro studies in simulated body fluid and artificial saliva. Changes in chemical composition and morphology after immersion were examined with FTIR spectroscopy and SEM imaging. Based on the conducted research, it can be stated that applied modifiers promote the biomineralization process. The roughness analysis confirmed prepared materials were characterized by the micrometer-scale topography. The materials morphology and roughness, and the morphology of the newly formed apatite deposit, were dependent on the type of the used modifier, and the artificial fluid used in in vitro studies.

Objective: The aim of the present research was to prepare metoprolol-loaded nanospheres. Metoprolol-loaded bovine albumin nanospheres were prepared by nanoprecipitation method. Metoprolol is beta-1-adrenergic receptor inhibitor specific to cardiac cells, thus producing negative chronotropic and ionotropic effect. Methods: Metoprolol nanospheres were prepared by nanoprecipitation method, using bovine serum albumin as polymer. The prepared nanospheres are evaluated for particle size evaluation, drug entrapment efficiency, and zeta potential. Drug-excipient compatibility was determined using Fourier-transform infrared spectroscopy. In vitro release and solubility of the drug from nanoparticles were determined. Results: The particle size of prepared metoprolol nanospheres was found to be always less than 200 nm. Maximum particle size was found to be 196±2.03 nm of batch 4 nanoparticles. Entrapment efficiency of prepared nanospheres was above 80% and maximum percentage entrapment efficiency was found to be 80.4±0.51%. It was found that the percentage entrapment efficiency and drug release were extended with increase in polymer concentration. Zeta potential of the optimized formulation was found to be −20.4 mV. In vitro drug release studies have shown the prolonged release of 94.5±0.54 up to 10 h. Drug release rate is extended with an increase in polymer concentration. Conclusion: Results have concluded that the albumin nanospheres loaded with metoprolol have reduced the blood pressure within 24 h and the prepared nanospheres are effective compared to other formulations and drug delivery.

Fluorescent Material

The levels of fluorescent material in the hemolymph of lobsters injected with serum proteins from lobster hemolymph labelled with fluorescein remained relatively constant over a 6-day test period; the levels in lobsters injected with bovine serum albumin labelled with fluorescein declined rapidly. A precipitin-like reaction was observed when lobster hemolymph serum was titrated with bovine serum albumin in vitro.
