A versatile method for constructing nonbiofouling and micropatterned surfaces bearing brush type poly(2-methacryloyloxyethyl phosphorylcholine) (MPC) on polymeric substrates using living radical polymerization with N,N-diethyldithiocarbamate moiety as a photoiniferter for microbiodevices was demonstrated. The polymeric photoiniferters comprised of 4-vinyl benzyl N,N-diethyldithiocarbamate (VBDC) and 2-ethylhexyl methacrylate (EHMA) were synthesized with variation of VBDC contents from 10% to 40% to easily tune the chain density of poly(MPC) grafted while the chain length was regulated by changing photoirradiation time. The characterizations of the poly(MPC)-modified surfaces were conducted by using attenuated total reflection infrared (ATR-IR), X-ray photoelectron spectroscopy (XPS), ellipsometric measurements, along with atomic force microscopy (AFM). The nonspecific protein adsorption from single and binary solutions of bovine plasma fibrinogen and bovine serum albumin was greatly suppressed on moderate to high chain density, moderate chain length of poly(MPC) and on smooth surfaces. The modified surfaces excellently eliminate cell adhesion of fibroblast-like cell L929 as well. Further, micropatterned-nonbiofouling poly(MPC) brush surface could be constructed using photomask with high fidelity.

Non-biofouling surfaces with polymer-based substrate were prepared for manufacturing microfluidic devices. It was done by constructing biocompatible poly(2-methacryloyloxyethyl phosphorylcholine(MPC)) brushes using surface-initiated graft polymerization method based on dithiocarbamate as photoiniferter. The density and length of the polymer chains were varied by changing the composition of the photoiniferter moiety in the base polymer (macrophotoiniferter) and the photoirradiation time, respectively. The molecular weight and thickness of the poly(MPC)- grafted chains were 320 kDa and 95±14 nm, respectively. Characterizations of the poly(MPC) modified surfaces were conducted by water contact angle, X-ray photoelectron spectroscopy, atomic force microscope. Protein adsorption resistance of these modified surfaces was then investigated by contacting with human plasma protein dissolved in phosphate buffered saline. These poly(MPC)-modified surfaces effectively reduced protein adsorption.

Stimuli-responsive nanoparticles are among the most popular research topics. In this study, two types of core-shell (polystyrene with a photoiniferter (PSV) as the core and diblock as the shell) polymer brushes (PSV@PNIPA-b-PAA and PSV@PAA-b-PNIPA) were designed and prepared using surface-initiated photoiniferter-mediated polymerization (SI-PIMP). Moreover, their pH- and temperature-stimuli responses were explored by dynamic light scattering (DLS) and turbidimeter under various conditions. The results showed that the conformational change was determined on the basis of the competition among electrostatic repulsion, hydrophobic interaction, hydrogen bonding, and steric hindrance, which was also confirmed by protein adsorption experiments. These results are not only helpful for the design and synthesis of stimuli-responsive polymer brushes but also shed light on controlled protein immobilization under mild conditions.

Adsorption and desorption of proteins on biomaterial surfaces play a critical role in numerous biomedical applications. Spherical diblock polymer brushes (polystyrene with photoiniferter (PSV) as the core) with different block sequence, poly(acrylic acid)-b-poly(N-(2-hydroxyethyl) acrylamide) (PSV@PAA-b-PHEAA) and poly(N-(2-hydroxyethyl) acrylamide)-b-poly(acrylic acid) (PSV@PHEAA-b-PAA) were prepared via surface-initiated photoiniferter-mediated polymerization (SI-PIMP) and confirmed by a series of characterizations including TEM, Fourier transform infrared (FTIR) and elemental analysis. Both diblock polymer brushes show typical pH-dependent properties measured by dynamic light scattering (DLS) and Zeta potential. It is interesting to find out that conformation of PSV@PAA-b-PHEAA uniquely change with pH values, which is due to cooperation of electrostatic repulsion and steric hindrance. High-resolution turbidimetric titration was applied to explore the behavior of bovine serum albumin (BSA) binding to diblock polymer brushes, and the protein adsorption could be tuned by the existence of PHEAA as well as apparent PAA density. These studies laid a theoretical foundation for design of diblock polymer brushes and a possible application in biomedical fields.

Les polymères à empreinte moléculaire (MIPs) sont des récepteurs synthétiques d’excellente affinité et sélectivité pour leurs cibles à l’instar des anticorps, leurs permettant de trouver des applications en détection chimique, bioimagerie, catalyse, etc. En tant que polymères, les MIPs peuvent être synthétisés en divers formats pour mieux s’adapter à leurs applications. Dans cette thèse, nous explorons l’emploi de la stéréolithographie à deux photons (TPS) pour la structuration arbitraire et précise des MIPs à travers la manipulation de lumière dans l’espace 3D d’un matériau polymérisable, contrairement aux méthodes traditionnelles qui ne produisent typiquement que des particules MIP et à d’autres techniques lithographiques « restreintes ». Tout d’abord, nous présentons une riche discussion sur la photopolymérisation et les techniques de photostructuration des MIPs, y compris la TPS. Ceci est suivi par l’application de la chimie thiol-yne dans la synthèse en plein air des MIPs sélectifs pour son utilisation potentielle dans la configuration en plein air de la TPS. Des opales aux « woodpiles » photoniques, nous exploitons la TPS sur des formulations différentes de résines photosensibles afin d’optimiser des conceptions MIP. Enfin, cela mène à la TPS des tableaux d’hexagone (nid d'abeille) de détails submicroniques à base des résines photosensibles commerciales pour leur fonctionnalisation ultérieure avec du MIP via un « photoiniferter ». Les nids d'abeilles MIP présentent de l’affinité et de la sélectivité pour leur cible, ce qui rend l'approche réussie en tant que stratégie générale pour la fabrication des conceptions submicronique des éléments de détection MIP
Molecularly imprinted polymers (MIPs) are synthetic receptors of excellent affinity and selectivity for their targets on par with antibodies, finding applications in chemical sensing, bioimaging, catalysis, etc. As polymers, MIPs can be synthesized into various formats to better suit their applications. In this PhD thesis, we explore the use of two-photon stereolithography (TPS) for the arbitrary and precise structuring of MIPs via light manipulation within the 3D space of a polymerizable material, which is in contrast to traditional methods that typically only produce MIP particles and to other “restrained” lithographic techniques. First, we present a rich discussion on photopolymerization and the existing techniques for photostructuring MIPs, including TPS. This is followed by the application of the thiol-yne chemistry in the open-air synthesis of selective MIPs for its potential use in the open-air setup of TPS. From opals to photonic woodpiles, we exploit TPS on different photoresist formulations to optimize MIP designs. Finally, this leads to the TPS of hexagon arrays (honeycombs) with sub-micron features on commercial photoresists for their subsequent MIP functionalization via a photoiniferter. The MIP honeycombs exhibit affinity and selectivity toward their target, rendering the approach successful as a general strategy for the fabrication of sub-micron MIP sensing element designs
