Query: An investigation into the nano-/micro-architecture of electrospun poly
  ({\epsilon}-caprolactone) and self-assembling peptide fibers   Self-assembling peptides (SAPs) have the ability to spontaneously assemble
into ordered nanostructures enabling the manufacture of "designer"
nanomaterials. The reversible molecular association of SAPs has been shown to
offer great promise in therapeutics via for example, the design of biomimetic
assemblies for hard tissue regeneration. This could be further exploited for
novel nano/micro diagnostic tools. However, self-assembled peptide gels are
often associated with inherent weak and transient mechanical properties. Their
incorporation into polymeric matrices has been considered as a potential
strategy to enhance their mechanical stability. This study focuses on the
incorporation of an 11-residue peptide, P11-8 (peptide sequence:
CH3CO-Gln-Gln-Arg-Phe-Orn-Trp-Orn-Phe-Glu-Gln-Gln-NH2) within a fibrous
scaffold of poly ({\epsilon}-caprolactone) (PCL). In this study an
electrospinning technique was used to fabricate a biomimetic porous scaffold
out of a solution of P11-8 and PCL which resulted in a biphasic structure
composed of submicron fibers (diameter of 100-700 nm) and nanofibers (diameter
of 10-100 nm). The internal morphology of the fabric and its micro-structure
can be easily controlled by changing the peptide concentration. The secondary
conformation of P11-8 was investigated in the as-spun fibers by ATR-FTIR
spectroscopy and it is shown that peptide self-assembly into \{b}eta-sheet
tapes has taken place during fiber formation and the deposition of the fibrous
web.
