Preparation and characterization of edible carboxymethyl cellulose films containing natural antibacterial agents: Lysozyme.

Carboxymethyl cellulose (CMC) films containing lysozyme (Lys) were prepared in this study and changes in properties of the films were investigated. Enhancement in mechanical properties was observed with increased Lys, maximum (0.05 g/100 mL) reached to 39.

Cu-Doped black phosphorus quantum dots as multifunctional Fenton nanocatalyst for boosting synergistically enhanced HO-guided and photothermal chemodynamic cancer therapy.

Chemodynamic therapy (CDT) is a cancer treatment that converts endogenous HO into hydroxyl radicals (˙OH) through Fenton reaction to destroy cancer cells. However, there are still some challenges in accelerating the Fenton reaction of CDT and improving the biodegradability of nanocatalysts. Herein, a multifunctional biomimetic BPQDs-Cu@GOD (BCG) Fenton nanocatalyst for boosting synergistically enhanced HO-guided and photothermal CDT of cancer is reported.

Chiral CuSe Nanoparticles for Enhanced Synergistic Cancer Chemodynamic/Photothermal Therapy in the Second Near-Infrared Biowindow.

Chiral nanomaterials have great potential in improving the clinical therapeutic effect due to the unique chiral selectivity of biosystems. However, such a promising therapeutic strategy has so far received little attention in cancer treatment. Here, we report a first chiral Fenton catalyst, d-/l-penicillamine-modified CuSe nanoparticles (d-/l-NPs), for enhanced synergistic cancer chemodynamic therapy (CDT) and photothermal therapy (PTT) under the second near-infrared (NIR-II) light irradiation.

Cancer-Erythrocyte Hybrid Membrane-Camouflaged Magnetic Nanoparticles with Enhanced Photothermal-Immunotherapy for Ovarian Cancer.

Cell-membrane-coated nanoparticles are widely studied due to their inherent cellular properties, such as immune escape and homologous homing. A cell membrane coating can also maintain the relative stability of nanoparticles during circulation in a complex blood environment through cell membrane encapsulation technology. In this study, we fused a murine-derived ID8 ovarian cancer cell membrane with a red blood cell (RBC) membrane to create a hybrid biomimetic coating (IRM), and hybrid IRM camouflaged indocyanine green (ICG)-loaded magnetic nanoparticles (FeO-ICG@IRM) were fabricated for combination therapy of ovarian cancer.

Characterization and film-forming mechanism of egg white/pullulan blend film.

Edible films based on pullulan (Pu) and egg white (EW) were prepared in this study. As the egg white proportion increased, the mechanical properties of the blend films initially increased and then decreased. The best mechanical properties occurred at the optimal proportion of Pu:EW = 1:1.

Effect of nano-TiO on the physical, mechanical and optical properties of pullulan film.

In this study, effects of nano-TiO on the microstructural, physical, mechanical and optical properties of pullulan films were investigated. The results showed that the addition of nano-TiO improved the water vapor barrier properties of the film due to the tortuous path formed by nano-TiO. When the concentration of nano-TiO was 0.

The impact of N-glycosylation on conformation and stability of immunoglobulin Y from egg yolk.

Immunoglobulin Y (IgY) is a new therapeutic antibody, and its applications in industry are very broad. To provide insight into the effects of N-glycosylation on IgY, its conformation and stability were studied. In this research, IgY was extracted from egg yolk and then digested by peptide-N4-(N-acetyl-beta-glucosaminyl) asparagine-amidase.
