In this study we fabricated a silicon-based stamp with various microchannel arrays, and demonstrated successful replication of the stamp microstructure on poly methyl methacrylate (PMMA) substrates. We used maskless UV lithography for the production of the micro-structured stamp. Thermal imprint lithography was used to fabricate microfeatured fluidic platforms on PMMA substrates, as well as to ...

In this study, thermodynamic properties, namely retention volume, infinitely dilute weight fraction activity coefficient, Flory–Huggins interaction parameter, solubility parameter of the polymer, partition coefficient and diffusion coefficients of the various solvents in poly(methyl methacrylate co butyl methacrylate) (PMMA co BMA) at infinite dilution of the solvent have been determined by inv...

Thin planar polymer films are model systems in a number of fields, including nanoand biotechnology. In contrast to reciprocal space techniques such as reflectivity or diffraction, secondary ion mass spectrometry SIMS can provide depth profiles of tracer labeled polymers in real space directly with sufficient depth resolution to characterize many important aspects in these systems. Yet, continue...

A new protein-polymer conjugate made of denatured bovine serum albumin (BSA) covalently bonded to poly(methyl methacrylate) (PMMA) is synthesized by attaching PMMA to acryloylated BSA followed by nanoparticle precipitation. Depending on the BSA to PMMA ratio, these conjugates self-assemble into uniform spherical nanoparticles which show "island" growth on the surface of the nanoparticles. This ...

The photostabilization of poly(methyl methacrylate) (PMMA) films having 2-(6-methoxynaphthalen-2-yl)propanoate and Sn(II), Ni(II), Zn(II) and Cu(II) complexes was investigated. The production of PMMA films containing such complexes (0.5% by weight) was carried out by the casting method using chloroform. The photostabilization activities of the compounds were determined by monitoring the hydroxy...

In this paper, different morphology and optical properties of poly (methyl methacrylate) (PMMA) thin films were investigated. Films were fabricated by spin coating under different preparation condition. PMMA polymers with molecular weight ranged from 15,000 to 996,000 were prepared in solution with various concentration ranged from 5.0 to 20.0 wt. %. The spin coating speed was controlled at 1,0...

A real-time three dimensional (3D) fluorescence imaging system incorporating wavelength-coded and multiplexed holographic gratings is presented. Holographic gratings formed in thick Phenanthrenquinone(PQ-) Doped Poly (methyl methacrylate) (PMMA) have narrowband spectral-spatial transmittance filtering properties to generate wavelengthspectrum selective multi-focal planes within a biological obj...

Superfine powders of poly (methyl methacrylate) (PMMA) have been prepared by means of an emulsion polymerization method. These have been used as templates in the synthesis of tetragonal phase mesoporous zirconia by the sol-gel method, using zirconium oxychloride and oxalic acid as raw materials. The products have been characterized by infrared spectroscopy, X-ray diffraction analysis, transmiss...

We demonstrate utilization of star-shaped polymers as high-density polymer brush coatings and their effectiveness to inhibit the adhesion of platelets and bacteria. Star polymers consisting of poly(2-hydroxyethyl methacrylate) (PHEMA) and/or poly(methyl methacrylate) (PMMA), were synthesized using living radical polymerization with a ruthenium catalyst. The polymer coatings were prepared by sim...
