Abstract

Phase-sensitive acoustic microscopy (PSAM) is used for investigating bio-soft matter systems constituting the important biopolymer and biomaterial chitosan. Incipient micro-analytic ways for the determination of mechanical properties from the simultaneously obtained amplitude and phase images, allow the coeval estimation of the depth of structures and acoustic velocities, from which the density, stiffness and other elastic parameters may be derived. Chitosan is an important derivative from chitin the major component of the carapace (also examined here) of living species like Daphnia. The results obtained exemplify the unique power of PSAM for revealing essential features and information in biological soft matter.
