Novel biomaterials with promising bone regeneration potential, derived from rich, renewable, and cheap sources, are reported. Thus, thin films were synthesized marine-derived (i.e., fish bones seashells) hydroxyapatite (MdHA) by pulsed laser deposition (PLD) technique. Besides the physical-chemical mechanical investigations, deposited also evaluated in vitro using dedicated cytocompatibility antimicrobial assays. The morphological examination of MdHA revealed fabrication rough surfaces,...

We report a study on the biocompatibility vs. thickness in case of titanium nitride (TiN) films synthesized 410 medical grade stainless steel substrates by pulsed laser deposition. The were grown nitrogen atmosphere, and their vitro cytotoxicity was assessed according to ISO 10993-5 [1]. Extensive physical-chemical analyses have been carried out deposited structures with various thicknesses order explain differences biological behavior: profilometry, scanning electron microscopy, atomic...

Abstract This study aimed to exploit two invasive plant species develop a novel, multifunctional, bioactive wound dressing based on microporous cellulosic sponge (CS) from Gleditsia triacanthos pods and functionalizing them with Phytolacca americana fruit extract. The CS was functionalized, lyophilized, characterized by Attenuated total reflectance–Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, contact angle, water absorption, retention capacity. In...
