“…28 PDA coating displays excellent biocompatibility and low cytotoxicity, making it a versatile platform for applications, including biomolecule immobilization, molecular surface imprinting for protein recognition, cells adhesion, and encapsulation. [29][30][31] Furthermore, PDA is also a major pigment of naturally occurring eumelanin. 32 PDA displays a lot of striking properties of naturally occurring eumelanin in terms of electrical, optical, and magnetic properties.…”

To enhance the therapeutic effects of chemotherapy on malignant melanoma, paclitaxel (PTX)-loaded methoxy poly(ethylene glycol)- b -poly(ε-caprolactone) nanoparticles (MPEG- b -PCL NPs) that had their surfaces modified with polydopamine (PTX-loaded MPEG- b -PCL NPs@PDA) were prepared as drug vehicles. The block copolymer MPEG- b -PCL was synthesized by ring-opening polymerization and characterized by proton nuclear magnetic resonance spectroscopy and gel permeation chromatography. The PTX-loaded NPs were prepared by a modified nanoprecipitation technique. The PTX-loaded NPs and PTX-loaded NPs@PDA were characterized in terms of size and size distribution, zeta potential, surface morphology, drug encapsulation efficiency, and drug release. Confocal laser scanning microscopy showed that coumarin-6-loaded NPs@PDA could be internalized by human melanoma cell line A875 cells. The cellular uptake efficiency of NPs was greatly enhanced after PDA modification. The antitumor efficacy of the PTX-loaded NPs@PDA was investigated in vitro by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and in vivo by a xenograft tumor model. The PTX-loaded NPs@PDA could significantly inhibit tumor growth compared to Taxol ® and precursor PTX-loaded NPs. All the results suggested that the PTX-loaded MPEG- b -PCL NPs that had their surfaces modified with PDA are promising nanocarriers for malignant melanoma therapy.

“…Three different formulations containing 5%, 10% and 15% of siloxane were synthesized using different mixing times to control sample morphology. The adsorption of the protein bovine serum albumin (BSA) was evaluated by using a colorimetric method [20] and by quartz crystal microbalance with dissipation monitoring (QCM-D) [21]. The adsorption data were correlated with the sample morphology.…”

Membrane fouling remains a major barrier to membrane separation, particularly obvious in polymer membranes. Dopamine (DA) is of great value as a precursor for conjugation hydrophilic molecules. In this study, PP hollow fibrous membranes were first modified by DA to form a layer of polydopamine (PDA) coating. Then taurine and glycidol were introduced respectively with assisted by PDA reactive layer, the prepared membranes corresponding to PP-T and PP-G membranes, respectively. PP and the modified PP membranes were confirmed by a thorough membrane characterization of ATR-FTIR, XPS, and FESEM measurements. The hydrophilic properties and permeability were measured by water contact angle (WCA) and permeation flux test. BSA was used to as model protein to evaluate the antifouling properties of the membranes. The results showed that taurine and glycidol were successfully introduced onto the membrane surface. The WCA of PP-T and PP-G membranes can be reduced to 328 and 268, and the flux recovery ratio increased around 90.6% and 89.8%, respectively. Based on the experimental results, taurine and glycidol effectively improved the hydrophilic and anti-fouling performance of PP membrane.
