“…In a previous work, ascorbyl palmitate was more easily released from TPP-crosslinked chitosan nanoparticles at low TPP concentration because of the low-density structure. 36 Previous studies showed a sustained-release ability of drugs (eg, mitoxantrone 37 and progesterone 38 ) from glutaraldehyde-crosslinked CAS microparticles, where the rate of drug release was found to decrease with the increase in the glutaraldehyde concentration.…”

“…Eugenol-loaded chitosan particles were prepared according to a modified method [8]. Chitosan solution (1.2% (w/v)) was prepared by agitating chitosan in an aqueous acetic acid solution (1% (v/v)) at ambient temperature until it reached homogenous solution.…”

“…O encapsulante geralmente atua como um carreador para a entrega controlada sob condições específicas, prolongando a atividade deste sistema. 81 A quitosana é um polímero natural e possui vantagens como a capacidade mucoadesiva, é atóxica e biodegradável, sendo um dos carreadores mais adequados para vários materiais. 81,105 Estudos na literatura demonstram que NPs de quitosana tem a vantagem das suas características de biodegrabilidade por diversos processos, como catálise enzimática e variações de pH, tornando-as importantes para a administração de fármacos.…”
