“…The thermoplastic elastomer-printed PTMP SAM showed a higher etch-resistance than the PDMS-printed SAM. [66] Other hydrophilic stamp materials were developed for printing of proteins and biomolecules. Hydrogel copolymers of 6-acryloyl-b-O-methylgalactopyranoside and ethylene glycol dimethacrylate on solid support were used as stamps for mCP.…”

Microcontact printing (µCP) offers a simple and low‐cost surface patterning methodology with high versatility and sub‐micrometer accuracy. The process has undergone a spectacular evolution since its invention, improving its capability to form sub‐100 nm SAM patterns of various polar and apolar materials and biomolecules over macroscopic areas. Diverse development lines of µCP are discussed in this work detailing various printing strategies. New printing schemes with improved stamp materials render µCP a reproducible surface‐patterning technique with an increased pattern resolution. New stamp materials and PDMS surface‐treatment methods allow the use of polar molecules as inks. Flat elastomeric surfaces and low‐diffusive inks push the feature sizes to the nanometer range. Chemical and supramolecular interactions between the ink and the substrate increase the applicability of the µCP process.

Three-dimensional, distendable bladder phantom for optical coherence tomography and white light cystoscopy

et al. 2014

Abstract. We describe a combination of fabrication techniques and a general process to construct a threedimensional (3-D) phantom that mimics the size, macroscale structure, microscale surface topology, subsurface microstructure, optical properties, and functional characteristics of a cancerous bladder. The phantom also includes features that are recognizable in white light (i.e., the visual appearance of blood vessels), making it suitable to emulate the bladder for emerging white light þ optical coherence tomography (OCT) cystoscopies and other endoscopic procedures of large, irregularly shaped organs. The fabrication process has broad applicability and can be generalized to OCT phantoms for other tissue types or phantoms for other imaging modalities. To this end, we also enumerate the nuances of applying known fabrication techniques (e.g., spin coating) to contexts (e.g., nonplanar, 3-D shapes) that are essential to establish their generalizability and limitations. We anticipate that this phantom will be immediately useful to evaluate innovative OCT systems and software being developed for longitudinal bladder surveillance and early cancer detection. © The Authors.Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…[1][2][3] Benefiting from these merits, it has been widely used in biomedicine, [4,5] microfluidic chips, [1,6,7] and soft lithography. [8][9][10][11] However, original PDMS is very hydrophobic with contact angle in the range of 90 o -102 o , which leads to the accumulation of proteins [12,13] or other hydrophilic chemical regents [6,12] on its surface, swelling by some organic solvents [14,15], or repelling aqueous solution into its microchannels in fluidic chip. [1,3,6,16] To make the surface of PDMS hydrophilic and maintain its elasticity, researchers have developed many methods, including physical adsorption, plasma treatment, plasma/ozone or UV/ozone oxidation, and surface grafting.…”

Homogenous Grafted Poly(acrylic acid) Brushes on Ultra-flat Polydimethlysiloxane (PDMS) Films by UV Irradiation

In this paper, hydrophilic poly(acrylic acid) (PAA) brushes were evenly grafted onto ultra-flat polydimethlysiloxane (PDMS) films by UV irradiation in a benzophenone (BP)/aceton/acrylic acid solution. The grafted films remain the elasticity of PDMS, which indicates the grafting reaction takes place at the superficial surface. But water affects the grafting depth much due to the good diffusion of monomers into the film.
