3. In vitro biomineralization of a novel hydroxyapatite/superhydrophilic multiwalled carbon nanotube nanocomposite using simulated body fluids
Nanobiomaterials based on superhydrophilic vertically-aligned multi-walled carbon nanotubes (VAMWCNT-O2) are promising for their properties and bone tissue biocompatibility. VAMWCNT-O2 films with nanohydroxyapatite (nHAp) aim to improve mechanical properties and biocompatibility of this new nanocomposite due to its resemblance to bone matrix structure. This

8. Estudo da esterilização e da calcificação in vitro de membranas de fibroina de seda para a aplicação como biomaterial / Study of sterization and in vitro calcification of silk fibroin membranes for biomaterial application
Silk fibroin has been widely explored for many biomedical applications, due to its biocompatibility, biodegradability and minimal inflammatory reactions. Sterilization is a fundamental step in biomaterials processing, and it must not alter in a negative way the functionality of medical devices. On the applicability of fibroin as a biomaterial, recent studies

10. In vitro and in vivo evaluation of lyophilized bovine bone biocompatibility
INTRODUCTION: The use of bone grafts in orthopedic, maxillofacial and dental surgery has been growing. Nevertheless, both fresh autografts and frozen allografts have limitations, and therefore, alternative synthetic or natural biomaterials, such as processed and lyophilized bovine bone graft have been developed. OBJECTIVE: To evaluate in vitro and in vivo bi

11. Avaliação da biocompatibilidade de magnetolipossomas à base de nanopartículas de maghemita
Nanobiotechnology represents an emerging and promising research field. Nanostructured materials, such as magnetic fluids and magnetoliposomes (MLs), have been proposed for drug-delivery systems and thermal-based cancer therapy amongst other several applications in biomedicine. In particular, MLs are physiologically stable structures, consisting of magnetic n
