“…It is reported that the introduction of saccharide residues in the side chain of a polymer increased the water solubility [45], so it is expected that the glucose residue in chitosan-DG will increase its water solubility. The lower DS (9.8%) derivative was dissolved in the water to give a transparent solution.…”

“…Since amphiphilic PVLA has both hydrophobic backbone and hydrophilic pendant chain, PVLA molecules in aqueous solution form a micelle structure, consisting of a hydrophobic inner core and hydrophilic outer shell. 24 It can be inferred that the lumpy parts shown in Figure 5a,b are the aggregates of micelles.

A surface of poly(l-lactic acid) (PLLA) was modified by coating with poly[N-p-vinylbenzyl-4-O-beta-d-galactopyranosyl-d-glucoamide] (PVLA), which was employed to improve the hepatocyte adhesion owing to its amphiphilic property and the presence of a hepatocyte recognition motif. We characterized the surface properties through water contact angle, electron spectroscopy for chemical analysis (ESCA), and scanning probe microscopy (SPM). The effect of PVLA coating on the efficiency of hepatocyte adhesion was evaluated by protein assay and optical microscopy. The surface morphology was under the influence of the concentration of PVLA coating solution and it played a critical role in hepatocyte adhesion. It was confirmed that galactose moieties in PVLA, which can bind to the asialoglycoprotein receptor (ASGPR) on hepatocytes, have a more dominant effect on hepatocyte adhesion than enhanced hydrophilicity. We suggest that the PVLA-PLLA system will be a useful method to improve hepatocyte cell seeding and adhesion onto scaffold matrices.

“…In this way, the exploration of novel fluoroalkyl end-capped oligomers containing numerous hydroxyl segments is of particular interest, from the developmental viewpoints of new fluorinated functional materials. In a variety of hydroxylated polymers, much attention has been focused on the synthetic sugar-containing polymers (glycopolymers), which possess the pendent gluconic residues (pentaol units), owing to their role as biomimetic analogues and their applications in biomedical and technological fields such as paints and cosmetics [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. In fact, poly(allylamine) can react with gluconolactone in water to provide the gluconamide-substituted polymers, successively affording the hydrogel through the interaction of the corresponding polymers with borax [ 20 ].…”

Fluoroalkyl end-capped vinyltrimethoxysilane oligomer [R F -(CH 2 -CHSi(OMe) 3 ) n -R F (R F -(VM) n -R F )] undergoes the sol-gel reaction in the presence of N-(3-triethoxysilylpropyl)gluconamide [Glu-Si(OEt) 3 ] under alkaline conditions to afford the corresponding fluorinated oligomeric silica nanocomposites containing gluconamide units [R F -(VM-SiO 3/2 ) n -R F /Glu-SiO 3/2 ]. These obtained nanocomposites were applied to the surface modification of glass to provide the unique wettability characteristics such as highly oleophobic/superhydrophobic and highly oleophobic/superhydrophilic on the modified surfaces under a variety of conditions. Such a highly oleophobic/superhydrophobic characteristic was also observed on the modified PET (polyethylene terephthalate) fabric swatch, which was prepared under similar conditions, and this modified PET fabric swatch was applied to the separation membrane for the separation of the mixture of fluorocarbon oil and hydrocarbon oil. The R F -(VM-SiO 3/2 ) n -R F /Glu-SiO 3/2 nanocomposites, which were prepared under lower feed amounts of basic catalyst (ammonia), were found to cause gelation in water. Interestingly, it was demonstrated that these gelling nanocomposites are also applied to the surface modification of the PET fabric swatch to give a highly oleophobic/superhydrophobic characteristic on the surface. On the other hand, the modified glass surfaces treated with the corresponding nanocomposite possessing no gelling ability were found to supply the usual hydrophobic characteristic with a highly oleophobic property. More interestingly, the wettability change on the modified PET fabric swatch from highly oleophobic to superoleophilic was observed, and remained superhydrophobic after immersing the modified PET fabric swatch into water.
