Authors’ contributions The work SN-38 presented here was carried out in collaboration among all authors. The experiments presented in this work were designed by PF and LFM. The pSi substrates were fabricated and functionalized by MA and characterized microscopically by PF and MA. Cell seeding Avelestat (AZD9668) and culture, cell viability, and cytotoxicity were carried out by UC, SFC, and RS. SEM characterization after 48 h-incubation was analyzed by PF. MA, PF, UC, SFC, JP, RS, and LFM analyzed and discussed the results obtained from the experiments. PF wrote the manuscript, and it was revised by all the authors (PF, MA, UC, SFC, JP, RS, and LFM). All authors read and approved the final manuscript.”
“Background The study of acoustic and elastic wave propagation in phononic crystals (PCs) [1–3] have been studied theoretically [4] and experimentally [5] in recent years. In analogy with the photonic band gap materials, emphasis in phononic crystals has been on achieving large acoustic band gaps within which propagation of sound is forbidden.
