Special Issue Information

Dear Colleagues,

The need to overcome the limits of current medical devices and food packaging materials has prompted many research groups to turn their attention towards techniques capable of modifying the surfaces of materials. This plays an essential role in defining the performance of a biomaterial, as the surface is more reactive than the core of the material. Therefore, the response of the human body to the implantation of a material, or the response of food to contact with a bioplastic, is a function of the reactions that occur at the tissue–implant/food–bioplastic interface.

Many macroscopic properties of materials (e.g. resistance to degradation and chemicals, hydrophilicity/hydrophobicity, bioactivity and biocompatibility, the refractive index, reflectance, photoluminescence and other optical properties) are related to the chemical and physical characteristics of the material surface. Therefore, surface modification can improve the implant integration process through the application of functional coatings to biologically implantable materials. This is a promising strategy to confer new properties to materials or to modify and improve existing ones (for example, the improvement of bioactivity and biocompatibility). Furthermore, surface modification can be employed to reduce food waste and the spread of plastics in the environment.

  • The aim of this Special Issue is to provide a forum for papers focused on the following:
  • The synthesis and characterization of new functionalized biomaterials;
  • Coatings containing natural extracts with antioxidant and/or anticancer properties;
  • Coatings for drugs with antibiotic and antibacterial properties;
  • Coatings containing synthetic or natural polymers able to improve the chemical–physical properties of biomaterials;
  • The characterization and modification of the surfaces of biomaterials already on the market.

The need to improve the expectancy and quality of life of subjects affected by disabling pathologies that require the replacement or regeneration of tissues or parts of the body has fueled the development of innovative, better-performing materials that are capable of integrating into and being tolerated by body tissues. Materials with these characteristics, i.e., bio-functionality, bio-safety, and biocompatibility, are defined as biomaterials. One of the many methods for producing such materials is the sol–gel technique. This process is mainly used for the preparation of ceramic oxides at low temperatures, through hydrolysis and polycondensation reactions of organometallic compounds within a hydroalcoholic solution. This study is based on a specific type of biomaterial: organic–inorganic hybrids. The aim of this study is to provide an overview of the advantages and disadvantages of the sol–gel technique, as well as describe the preparation and chemical and biological characterization, uses, and future prospects of these biomaterials. In particular, the use of plant drugs as organic components of the hybrid material is the innovation of this manuscript. The biological properties of plant extracts are numerous, and for this reason, they deserve great attention from the scientific community. Full article
