“…Surface energy and contact angle have inverse relationship as shown in Figure 4. Generally, higher surface energy of material caused more bioadhesion and reduced antialgal activity [35]. But in this study, increase of surface energy did not lead to decrease of antialgal activities.…”

Polystyrene (PS) was blended with polyethylene glycol (PEG) and silver sulfadiazine (SS) with different weight proportions to form polymeric blends. These synthesized blends were preliminary characterized in terms of functional groups through the FTIR technique. All compositions were subjected to thermogravimetric analysis for studying thermal transition and were founded thermally stable even at 280°C. The zeta potential and average diameter of algal strains of Dictyosphaerium sp. (DHM1), Dictyosphaerium sp. (DHM2), and Pectinodesmus sp. (PHM3) were measured to be -32.7 mV, -33.0 mV, and -25.7 mV and 179.6 nm, 102.6 nm, and 70.4 nm, respectively. Upon incorporation of PEG and SS into PS blends, contact angles were decreased while hydrophilicity and surface energy were increased. However, increase of surface energy did not led to decrease of antialgal activities. This has indicated that biofilm adhesion is not a major antialgal factor in these blended materials. The synergetic effect of PEG and SS in PS blends has exhibited significant antialgal activity via the agar disk diffusion method. The PSPS10 composition with 10 w / w % PEG and 10 w / w % SS has exhibited highest inhibition zones 10.8 mm, 10.8 mm, and 11.3 mm against algal strains DHM1, DHM2, and DHM3, respectively. This thermally stable polystyrene blends with improved antialgal properties have potential for a wide range of applications including marine coatings.

“…However, a low EWC (less than 40%) limits their utility. To improve the performance of polyHEMA hydrogels, the hydrophilic monomer, SBMA, which can bind water molecules via ionic-induced hydration, was added [ 12 ]. First, the different ratios of HEMA and SBMA to investigate their properties were evaluated ( Table S1 ).…”

“…Recently, zwitterionic poly(sulfobetaine methacrylate) (polySBMA), which carries both positively and negatively charged ions in a chemical structure, has attracted interest. The presence of both ions allow these hydrogels to maintain electrical neutrality and produce strong interactions with water molecules, resulting in high hydration and non-fouling properties [ 12 , 13 , 14 ]. In addition, sulfobetaine ligands can also act as effective mineral nucleating sites [ 15 ].…”

This study developed a tannic acid (TA)-supplemented 2-hydroxyethyl methacrylate-co-sulfobetaine methacrylate (HEMA-co-SBMA) nanocomposite hydrogel with mineralization and antibacterial functions. Initially, hybrid hydrogels were synthesized by incorporating SBMA into the HEMA network and the influence of SBMA on the chemical structure, water content, mechanical properties, and antibacterial characteristics of the hybrid HEMA/SBMA hydrogels was examined. Then, nanoclay (Laponite XLG) was introduced into the hybrid HEMA/SBMA hydrogels and the effects evaluated of the nanoclay on the chemical structure, water content, and mechanical properties of these supplemented hydrogels. The 50/50 hybrid HEMA/SBMA hydrogel with 30 mg/mL nanoclay showed outstanding mechanical properties (3 MPa) and water content (60%) compared to pure polyHEMA hydrogels. TA then went on to be incorporated into these hybrid nanocomposite hydrogels and its effects investigated on biomimetic mineralization. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) showed that bone-like spheroidal precipitates with a Ca/P ratio of 1.67% were observed after 28 days within these mineralized hydrogels. These mineralized hydrogels demonstrated an almost 1.5-fold increase in compressive moduli compared to the hydrogels without mineralization. These multifunctional hydrogels display good mechanical and biomimetic properties and may have applications in bone regeneration therapies.

“…Protein molecular behavior on surfaces or at interfaces determines protein property and function, which greatly impacts many applications and research fields, especially for those involving interfacial proteins such as biosensors, antifouling coatings, biomedical implants, membranes used for bioseparation, and protein antibody drugs. [1][2][3][4][5][6][7][8][9][10][11] In order to rationally design surfaces/interfaces to optimize interfacial protein properties and functions through controlling protein interfacial behavior, it is important to develop powerful tools to investigate molecular structure and molecular behavior of proteins at various interfaces. Many analytical techniques have been developed for characterizing protein structures and behavior, such as X-ray diffraction, nuclear magnetic resonance (NMR), attenuated total reflection -FTIR (ATR-FTIR), cryoelectron microscopy (cryo-EM), quartz crystal microbalance (QCM), etc., leading to important knowledge about protein molecules.…”
