Special Issue Information

Dear Colleagues,

Research in the field of materials science and engineering has advanced greatly in recent decades, especially in the field of biocompatible materials, on the one hand, medicine needs effective solutions to remedy health problems, and on the other hand, certain classes of biomaterials have confirmed their usefulness in ameliorating/curing certain diseases.

This Special Issue aims to highlight new types of advanced biomaterials and advanced technologies, applicable in medicine and biology, but also as tools for research. Studies focusing on the theoretical simulation, computerized procedures, mathematical algorithms, and optimal research techniques applied to biocompatible materials are also welcome. Researchers involved in the field of biomaterials and related disciplines (science, engineering, and manufacturing industry) are invited to publish their recent studies in this Special Issue.

Abstract
Biodegradable particles were developed using poly-ε-caprolactone and gelatin carriers containing different concentrations of Allium sativum essential oil (EO) (360 µg/mL, 420 µg/mL, and 460 µg/mL). Atomic force microscopy was useful to evaluate the particles’ surface based on morphological parameters. The particles’ size varied [...] Read more.
Biodegradable particles were developed using poly-ε-caprolactone and gelatin carriers containing different concentrations of Allium sativum essential oil (EO) (360 µg/mL, 420 µg/mL, and 460 µg/mL). Atomic force microscopy was useful to evaluate the particles’ surface based on morphological parameters. The particles’ size varied from 150 nm to 300 nm. The diameter was related to the increase of the particles’ height as a function of the EO concentration, influencing the roughness of the surface core values (from 20 to 30 nm) and surface irregularity. The spatial parameters Str (texture aspect ratio) and Std (texture direction) revealed low spatial frequency components. The hybrid parameters Sdq (root mean square gradient) and Sdr (interfacial area ratio) also increased as a function of the EO concentration, revealing fewer flat particles. On the other hand, the functional parameters (inverse areal material ratio and peak extreme height) suggested differences in surface irregularities. Higher concentrations of EO resulted in greater microtexture asperity on the particles’ surface, as well as sharper peaks. The nanoscale morphological surface analysis allowed the determination of the most appropriate concentration of encapsulated EO, influencing statistical surface parameters. Full article
