Abstract

Self-assembly of bioinspired functional materials with ordered organization on the nano- and microscale is attracting a lot of interest due to its versatility, structural simplicity, cost efficiency, and biocompatibility. The optical properties of the FFMT's were probed by means of optical, confocal, and multiphoton microscopies combined with spectroscopy characterization. Moreover, morphology changes of the samples were confirmed by scanning electron microscopy (SEM). The possibility to control the position and spatial confinement of the thermally induced green luminescence from FFMT's through laser treatment is a reliable and simple way for a controlled optical response of peptide tubes and for a fundamental step towards future applications in photonic integrated circuits. The appearance of TPL/SPL have never been observed before in the visible spectral range for both hexagonal and orthorhombic crystal structures, since their optical activity have always been observed in the UV range.
