Abstract
Biofouling is a major disruptive process affecting the fuel efficiency and durability of maritime vessel coatings. Previous research has shown that amphiphilic coatings consisting of a siloxane backbone functionalized with hydrophilic moieties are effective marine antifouling and fouling-release materials. Poly(ethylene glycol) (PEG) has been the primary hydrophilic component used in such systems. Recently, the morpholine group has emerged as a promising compact alternative in antifouling membranes but is yet to be studied against marine foulants. In this work, the use of morpholine moieties to generate amphiphilicity in a poly(dimethylsiloxane) (PDMS)-based antifouling and fouling-release coating was explored. Two separate coating sets were investigated. The first set examined the incorporation of an N-substituted morpholine amine, and while these coatings showed promising fouling-release properties for Ulva linza, they had unusually high settlement of spores compared to controls. Based on those results, a second set of materials was synthesized using an N-substituted morpholine amide to probe the source of the high settlement and was found to significantly improve antifouling performance. Both coating sets included PEG controls with varying lengths to compare the viability of the morpholine structures as alternative hydrophilic groups. Surfaces were evaluated through a combination of bubble contact angle goniometry, profilometry, X-ray photoelectron spectroscopy (XPS), and marine bioassays against two soft fouling species, U. linza and Navicula incerta, known to have different adhesion characteristics.

Abstract
![]()
Surface-initiated controlled
radical polymerization is a popular technique for the modification
of biomaterials with, for example, antifouling polymers. Here, we
report on the functionalization of a supramolecular biomaterial with
zwitterionic poly(sulfobetaine methacrylate) via atom transfer radical
polymerization from a macroinitiator additive, which is embedded in
the hard phase of the ureido-pyrimidinone-based material. Poly(sulfobetaine
methacrylate) was successfully polymerized from these surfaces, and
the polymerized sulfobetaine content, with corresponding antifouling
properties, depended on both the macroinitiator additive concentration
and polymerization time. Furthermore, the polymerization from the
macroinitiator additive was successfully translated to functional
electrospun scaffolds, showing the potential for this functionalization
strategy in supramolecular material systems.

Incorporation of silver stearate nanoparticles in methacrylate polymeric monoliths for hemeprotein isolation. OPEN CHEM 2020.

Abstract
AbstractA unique method was used to synthesize extremely stable silver stearate nanoparticles
(AgStNPs) incorporated in an organic-based monolith. The facile strategy was then
used to selectively isolate hemeproteins, myoglobin (Myo) and hemoglobin (Hb). Ethyl
alcohol, silver nitrate, and stearic acid were, respectively, utilized as reducing
agents, silver precursors, and capping agents. The color changed to cloudy from
transparent, indicating that AgStNPs had been formed. AgStNP nanostructures were then
distinctly integrated into the natural polymeric scaffold. To characterize the
AgStNP–methacrylate polymeric monolith and the silver nanoparticles,
energy-dispersive X-ray (EDX), scanning electron microscopy (SEM), and
Fourier-transform infrared (FT-IR) spectroscopy were used. The results of the SEM
analysis indicated that the AgStNP–methacrylate polymeric monolith’s
texture was so rough in comparison with that of the methacrylate polymeric monolith,
indicating that the extraction process of the monolith materials would be more
efficient because of the extended surface area of the absorbent. The comparison
between the FT-IR spectra of AgStNPs, the bare organic monolith, and
AgStNP–methacrylate polymeric monolith confirms that the AgStNPs were
immobilized on the surface of the organic monolith. The EDX profile of the built
materials indicated an advanced peak of the Ag sequence which represented an Ag atom
of 3.27%. The results therefore established that the AgStNPs had been successfully
integrated into the monolithic materials. Extraction efficiencies of 92% and 97% were
used to, respectively, recover preconcentrated Myo and Hb. An uncomplicated method is
a unique approach of both fabrication and utilization of the nanosorbent to
selectively isolate hemeproteins. The process can further be implemented by using
other noble metals.

Abstract
Surface-functionalized microparticles are relevant to fields spanning engineering and biomedicine, with uses ranging from cell culture to advanced cell delivery. Varying topographies of biomaterial surfaces are also being investigated as mediators of cell-material interactions and subsequent cell fate. To investigate competing or synergistic effects of chemistry and topography in three-dimensional cell cultures, methods are required to introduce these onto microparticles without modification of their underlying morphology or bulk properties. In this study, a new approach for surface functionalization of poly(lactic acid) (PLA) microparticles is reported that allows decoration of the outer shell of the polyesters with additional polymers via aqueous atom transfer radical polymerization routes. PLA microparticles with smooth or dimpled surfaces were functionalized with poly(poly(ethylene glycol) methacrylate) and poly[N-(3-aminopropyl)methacrylamide] brushes, chosen for their potential abilities to mediate cell adhesion. X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry analysis indicated homogeneous coverage of the microparticles with polymer brushes while maintaining the original topographies. These materials were used to investigate the relative importance of surface chemistry and topography both on the formation of human immortalized mesenchymal stem cell (hiMSCs) particle-cell aggregates and on the enhanced contractility of cardiomyocytes derived from human-induced pluripotent stem cells (hiPSC-CMs). The influence of surface chemistry was found to be more important on the size of particle-cell aggregates than topographies. In addition, surface chemistries that best promoted hiMSC attachment also improved hiPSC-CM attachment and contractility. These studies demonstrated a new route to obtain topo-chemical combinations on polyester-based biomaterials and provided clear evidence for the predominant effect of surface functionality over micron-scale dimpled topography in cell-microparticle interactions. These findings, thus, provide new guiding principles for the design of biomaterial interfaces to direct cell function.
