Electrospinning of Diphenylalanine Nanotubes

Abstract

Electrospinning from concentrated diphenylalanine solutions in a low‐boiling‐point solvent results in tubes that are chemically identical to self‐assembled tubes, but show different morphologies, especially extreme lengths. Electrospinning of tubes offers more possibilities for manipulation, for example, bridging electrodes in parallel orientation, a possible patterning strategy for electrospun material.

Micropatterning of Electrospun Polyurethane Fibers Through Control of Surface Topography

“…[24] However, the motion after ejection is controlled by electrostatic forces exerted by the external field, collector, and any adjacent charged fibers. [7][8][9][10][18][19][20][21] In the flat collector plate setup, there is no preferential direction in the plane of the collector resulting in a random fiber mesh. Whereas, a patterned collector substrate results in selective fiber deposition and arrangement due to an increase in Coulomb interactions with the raised topographical features of the collector.…”

“…[7][8][9][10] Spooling setups induce specific fiber orientations by physical manipulation of the resulting fibers using a moving collector stage, [11,12] revolving disk, [13] or rotating mandrel. [14] Modulation of the electric field with different setups has been used to create a range of fiber geometries including leaf patterns, [15] aligned fibers stacks, [16] and fiber arrays with grounded rings to wind into yarn.…”

Biosensors Based on Biological Nanostructures

“…In this process a fluid material is accelerated and drawn trough an electric field producing structures with reduced diameters. In the work of Singh et al (Singh, Bittner et al, 2008) + NH 3 -Phe-Phe-COO -nanotubes were prepared from solution in HFP. Then, this solution was diluted in water to 2.9 mmol L -1 of concentration and sonicated for 1 hour.…”

Electrospun starch acetate nanofibers: Development, properties, and potential application in drug delivery

“…At lower polymer concentration in the spinning solution, the low entanglement of the SA polymer chains did not allow full stretch of the spinning solution, leading to beaded fibers. 20 The uneven and beaded fibers broke first under tension, resulting in low tenacities of the SA nanofibers. As the SA concentration increased from 20 to 24% (wt %), the tenacity of SA nanofibers decreased to 12.0 MPa.…”
