Vertically Aligned Peptide Nanostructures Using Plasma-Enhanced Chemical Vapor Deposition
In this study, we utilize plasma-enhanced
chemical vapor deposition
(PECVD) for the deposition of nanostructures composed of diphenylalanine.
PECVD is a solvent-free approach and allows sublimation of the peptide
to form dense, uniform arrays of peptide nanostructures on a variety
of substrates. The PECVD deposited d-diphenylalanine nanostructures
have a range of chemical and physical properties depending on the
specific discharge parameters used during the deposition process
3D Printing of Regenerated Silk Fibroin and Antibody-Containing Microstructures via Multiphoton Lithography
Regenerated
silk fibroin, a biopolymer derived from silkworm cocoons,
is a versatile material that has been widely explored for a number
of applications (e.g., drug delivery, tissue repair, biocompatible
electronics substrates, and optics) due to its attractive biochemical
properties and processability. Here, we report on the free-form printing
of silk-based, 3D microstructures through multiphoton lithography.
Utilizing multiphoton lithography in conjunction with specific photoinitiator
chemistry and postprint cross-linking, a number of microarchitectures
were achieved including self-supporting fibroin arches. Further, the
straightforward production of high fidelity and biofunctional protein
architectures was enabled through the printing of aqueous fibroin/immunoglobulin
solutions
