The precursor co-polyesters were spin-coated on a benzophenone-functionalized silicon wafer to form ca. 60 nm films and drop-casted on glass to form ∼32 μm films. The copolymers were cross-linked via UV irradiation at 365 nm. The degradation of films was studied by immersing the specimens in aqueous buffers of different pH values. The results show that both the pH of buffer solutions and gel fractions of networks affect the degradation rate. The coatings show good bovine serum albumin resistance capability. By adjusting the fractions of monomers, the degradation rate and degree of hydration (e.g., swelling ratio) are controllable.}, number={4}, journal={LANGMUIR}, publisher={American Chemical Society (ACS)}, author={Mu, Gaoyan and Genzer, Jan and Gorman, Christopher B.}, year={2022}, month={Jan} }

After UV crosslinking, soaking the films in a good solvent (tetrahydrofuran) removed uncrosslinked material, and the resulting film gel fractions were calculated. These network films were then degraded in buffer solutions of varying pH values. The degradation of networks with lower gel fraction (fewer crosslinks) was faster and followed first-order kinetics. In contrast, the denser network degraded slower and followed zeroth-order kinetics. The lower gel fraction networks possess a higher swelling ratio and resist bovine serum albumin (BSA) adsorption better by entropic shielding and faster degradation. In comparison, higher gel fraction networks with higher EBP mole fractions adsorb more BSA due to hydrophobic interactions and slower degradation.}, number={30}, journal={LANGMUIR}, publisher={American Chemical Society (ACS)}, author={Mu, Gaoyan and Pandiyarajan, C.

They can both self-assemble into hollow spherical nanostructures in water/organic mixed solvents, as confirmed by light scattering and TEM techniques, yet they possess completely different mechanisms and driving forces. With the PS linkers, the hybrid forms bilayer vesicles similar to surfactants; while without the PS linkers, the hybrid behaves like hydrophilic macroions and assembles into single-layered, vesicle-like “blackberry”-type structure. Consequently, the trend of the assembly size in response to the change of the solvent polarity is different for the two scenarios. This work shows a simple, universal approach of controlling the mechanism and product of the self-assembly process via minor adjustment of the organic–inorganic hybrid structures.}, number={13}, journal={Macromolecules}, publisher={American Chemical Society (ACS)}, author={Zhang, Wei and Chu, Yang and Mu, Gaoyan and Eghtesadi, Seyed Ali and Liu, Yuchu and Zhou, Zhe and Lu, Xinlin and Kashfipour, Marjan Alsadat and Lillard, Robert Scott and Yue, Kan and et al.}, year={2017}, month={Jun}, pages={5042–5050} }

A series of model amphiphilic chain-like giant molecules was designed and synthesized by interconnecting both hydrophobic and hydrophilic molecular nanoparticles in precisely defined sequence and composition to investigate their sequence-dependent phase structures. Not only compositional variation changed the self-assembled supramolecular phases, but also specific sequences induce unconventional phase formation, including Frank–Kasper phases. The formation mechanism was attributed to the conformational change driven by the collective hydrogen bonding and the sequence-mandated topology of the molecules. These results show that sequence control in synthetic polymers can have a dramatic impact on polymer properties and self-assembly.}, number={47}, journal={Angewandte Chemie International Edition}, publisher={Wiley}, author={Zhang, Wei and Lu, Xinlin and Mao, Jialin and Hsu, Chih-Hao and Mu, Gaoyan and Huang, Mingjun and Guo, Qingyun and Liu, Hao and Wesdemiotis, Chrys and Li, Tao and et al.}, year={2017}, month={Oct}, pages={15014–15019} }
