Sustainable carbon dots loaded into carboxymethylcellulose based hydrogels for ...
Rodrigues, Jordane S.; Brandão, Pedro; Duarte, Sofia O. D.; Silveira, Izabela Boueri da; Leite, Maria de Fátima; Gonçalves, Max P.Abstract: Background/Objectives: The development of innovative materials for disease diagnostics and therapeutics is a fast-growing area of scientific research. In this work, we report the development of innovative hydrogels incorporating carbon dots (Cdots) for bioimaging purposes. Methods: The Cdots were prepared using a sustainable and low-cost process, starting with an underused fiber from the Brazilian sem...
Attachment and proliferation of osteoblasts on lithium-hydroxyapatite composites
Schainberg, Ana Paula Muchon; Valério, Patrícia; Zonari, Alessandra; Oktar, Faik Nushek; Ozyegin, Luftie Sevgi; Graça, Manuel Pedro FernandesThe biocompatibility and bioactivity properties of hydroxyapatites (HAs) modified through lithium addition were investigated. Hydroxyapatites obtained from bovine bone were mixed with lithium carbonate (Li), in the proportions of 0.25, 0.50, 1.00, and 2.00%wt, and sintered at 900◦, 1000◦, 1100◦, 1200◦, and 1300◦C, creating LiHA samples. The osteoblast culture behavior was assessed in the presence of these LiHA ...
