“…reported that the hydrogen silsesquioxane (HSQ) transferred pattern with 35 nm line width was obtained onto Si surface. [ 45 ] Nanocontact printing process has also been used to fabricate dot arrays of different size features. A micromachined elastomeric PDMS stamp with two dimensional arrays of pyramidal tips were used to array dot pattern with variable dot size and density.…”

Biomimetic Nanopatterns as Enabling Tools for Analysis and Control of Live Cells

It is becoming increasingly evident that cell biology research can be considerably advanced through the use of bioengineered tools enabled by nanoscale technologies. Recent advances in nanopatterning techniques pave the way for engineering biomaterial surfaces that control cellular interactions from the nano- to the microscale, allowing more precise quantitative experimentation capturing multi-scale aspects of complex tissue physiology in vitro. The spatially and temporally controlled display of extracellular signaling cues on nanopatterned surfaces (e. g., cues in the form of chemical ligands, controlled stiffness, texture, etc.) that can now be achieved on biologically relevant length scales is particularly attractive enabling experimental platform for investigating fundamental mechanisms of adhesion-mediated cell signaling. Here, we present an overview of bio-nanopatterning methods, with the particular focus on the recent advances on the use of nanofabrication techniques as enabling tools for studying the effects of cell adhesion and signaling on cell function. We also highlight the impact of nanoscale engineering in controlling cell-material interfaces, which can have profound implications for future development of tissue engineering and regenerative medicine.

“…As with other material classes addressed in this review, alternative stamp materials are sometimes more desirable than PDMS for printing. For example, due to its relatively high modulus and ability to resist solvent swelling,327 PMMA is useful for transfer printing of materials such as resists for electron beam lithography, hydrogen silsequioxane (HSQ), and conductive silver paste 327. Previously described PUA stamps have also been used to print polymers, by first coating their surfaces with aluminum to facilitate release, and then with a desired polymer film (such as poly(vinyl acetate) (PVAc)).…”

Transfer Printing Techniques for Materials Assembly and Micro/Nanodevice Fabrication

et al. 2012

Transfer printing represents a set of techniques for deterministic assembly of micro-and nanomaterials into spatially organized, functional arrangements with two and three-dimensional layouts. Such processes provide versatile routes not only to test structures and vehicles for scientific studies but also to high-performance, heterogeneously integrated functional systems, including those in flexible electronics, three-dimensional and/or curvilinear optoelectronics, and bio-integrated sensing and therapeutic devices. This article summarizes recent advances in a variety of transfer printing techniques, ranging from the mechanics and materials aspects that govern their operation to engineering features of their use in systems with varying levels of complexity. A concluding section presents perspectives on opportunities for basic and applied research, and on emerging use of these methods in high throughput, industrial-scale manufacturing.

“…However, patterning the surface chemistry and topology at the molecular level is required to control both the adsorption of proteins and cells at well-defined locations on substrates for high sensitivity bio-devices fabrication [1 -3]. Nakamatsu et al had fabricated a two-layered soft template: a film of polyethylene laminated on a poly(methyl methacrylate) (PMMA) sheet, and obtained a 35 nm HSQ transferred line pattern onto a Si surface at room temperature with 0.3 MPa press pressure [4]. Therefore, nanocontact printing of organosilanes can be utilized to generate nanoscale patterns at low temperature and pressure for the accurate placement of proteins and cells on silicon oxide substrates.…”

Nanocontact printing using hydrogen silsesquioxane (HSQ) soft stamps is studied for nanobio device fabrications in this work. The stamps with designed linewidth 80-200 nm were fabricated by low-dose e-beam lithography on HSQ films. The contact printing technique by using aminosilane as the ink on O2 plasma treated HSQ/Si substrates was developed. The plasma treatment, stamping force and stamping time were manipulated, and afterwards the transferred patterns were examined by the utilization of atomic force microscope and scanning electron microscope. Experimental results demonstrate that the nano-features on the HSQ stamps can be successfully transferred onto the substrates and passed a 3M tape peeling test under specific conditions in the range of 100-200 W O2 plasma treatment for 30 s. Nanolines with printed linewidth 97-205 nm were obtained. The nanopatterning of an antibody affinipure goat anti-mouse IgG(H+L) was also demonstrated onto the transferred aminosilane pattern surfaces for bio-device fabrication.
