Here we describe a unique strategy for creating biocompatible, layered matrices with continuous interfaces between distinct layers for tissue engineering. Such a scaffold could provide an ideal customizable environment to modulate cell behavior by various biological, chemical or mechanical cues

White Luminescence from Multiple-dye-doped Electrospun DNA Nanofibers by Fluorescence Resonance Energy Transfer
Angewandte Chemie (International Ed. in English). 2009 | Pubmed ID: 19504507
A DNA spin-off: Electrospinning of DNA complexes gives nanofibers with a highly ordered morphology that allows homogeneous distribution of encapsulated multiple chromophores. The emission color can be controlled by suitable choice of the donor-acceptor pair and the doping ratio. Pure white-light emission from nanofibers is demonstrated (see picture).
ACS Applied Materials & Interfaces. Oct, 2009 | Pubmed ID: 20355838
A simplified approach to constructing a composite material comprised of aligned electrospun nanofibers onto a flexible substrate consisting of a microfilament yarn is presented. The metal-coated knit patterns of the microfilament yarn play the role of the parallel electrode, required for the alignment of electrospun nanofibers. Hybrid materials with knitted textile as a support material and aligned high-surface-area nanofibers could represent ideal materials for use in the filtration, optical, and biomedical industries.

An efficient cascade FRET was realized in solid state DNA-CTMA thin films using a three chromophore system without any covalent attachments. The extent of energy transfer from Cm102 to SRh was studied and found to improve eight-fold using the bridging dye Pm567.

An adaptable density gradient multilayer polymerization (DGMP) method facilitates simple fabrication of complex multicompartment scaffolds with structurally continuous interfaces. Solvent density liquid-liquid phase segregation compartmentalizes varied mechanical and chemical cues independently. Bulk photopolymerization produces stratified three-dimensional and two-dimensional matrices. Cells attach to patterned adhesion peptides on biomimetic 2D substrates.
