Description
General Remarks: This dataset accompanies the paper titled "Micromechanical behavior of the apple fruit cuticle investigated by Brillouin light scattering microscopy" (Communications Biology 2025, accepted)
Files contained: It contains the extracted Brillouin source data for the mechanical evaluation and images, the tensile test data, the refractive index data, and the differential scanning calorimetry data. Readme files contain information about the devices used and importent parameters.
Remark on Brillouin light scattering: n the Brillouin light scattering process, incoming photons scatter from thermally induced density fluctuations within a sample. These density fluctuations are acoustic phonons that travel through the sample at the speed of sound, inducing a small Doppler shift. By measuring this shift and considering the refractive index of the sample, the speed of sound can be determined. With knowledge of the sample's density, the mechanical longitudinal modulus can also be derived. This methodology can be coupled to an optical microscope, allowing for contact-free microscopical mechanical measurements.
