From Micro- to Nano- Patterning: Manipulating the Extracellular Matrix and Directing Cell Organization, Migration & Adhesion

Moten A., Harvard Univeristy/Massachusetts Institute of Technology, US

Cells are inherently sensitive to local mesoscale and microscale patterns of chemistry and topography. Recent research has investigated how surface mechanics might dictate cell behavior, affecting both cell function and differentiation. This study professes that [...]

Advanced CryoTEM and Tomography for Two- and Three-Dimensional Nano-Characterisation of Soft Matter

Sourty E., de Haas F., Frederik P.M., Frederik P.M., Loos J., Stokes D.J., Hubert D.H.W., FEI Company, NL

Recent advances in transmission electron microscopy (TEM) mean that we are able to achieve unprecedented resolution at the atomic level. Furthermore, improved methods for obtaining and reconstructing tilt series projections allow us to create high [...]

Nanofabrication of Biomaterial, CNT and Organic Polymer Patterned Thinfilms using Piezoelectric Ink Jet Printing

Sumerel J.L., Deravi L.F., Wright D.W., Dimatix, Inc., US

In contrast to thermal ink jetting that uses heat to generate fluid drop ejection, MEMS-constructed piezoelectric ink jet printheads use a thin PZT slab bonded to a silicon diaphragm to generate acoustic energy that drives [...]

Patterned nanofiber meshes for biomedical applications

Neves N.M., Campos R., Pedro A., Cunha J., Macedo F., Reis R.L., University of Minho, PT

The typical end-product of the electrospinning process is a randomly aligned fibre mesh or membrane. This is a result of the electric field generated between the drop of polymer solution at the needle and the [...]

Overview – Nanoparticulate Dry (Flame) Synthesis & Applications

Pratsinis S.E., ETH Zürich, CH

Flame synthesis is a scalable technology that was developed largely by valiant evolutionary research for manufacture of commodities (e.g. carbon blacks, fumed silica and pigments). In the last 5-10 years, however, major advances in the [...]
