Araújo, Alyne R. de; Nunes, Lívio C. C.; Oliveira, Karla C. B. F.; Carvalho, Maria G. F. M.; Cardoso, Juliana C.; Severino, PatriciaThe respiratory protection equipment (RPE) used by health professionals consists of an essential device to prevent infectious diseases, especially those caused by biological agents such as the coronavirus (SARS-CoV-2). The current epidemiological panorama is worrying, and the context of creation and production of the mask has emerged as an alternative to RPE to face the public health crisis worldwide. The aim o...
Quaternized cashew gum: An anti-staphylococcal and biocompatible cationic polym...
Quelemes, Patrick V.; Araújo, Alyne R. de; Plácido, Alexandra; Delerue-Matos, Cristina; Maciel, Jeanny S.; Bessa, Lucinda J.; Ombredane, Alicia S.Chemical modifications to cashew gum (CG) structure have been previously reported to obtain new physicochemical characteristics, however until now there were no reports of modifications by introduction of new functional groups to add cationic character. This study presents a quaternization route for CG using a quaternary ammonium reagent. The chemical features of the quaternized cashew gum derivatives (QCG) wer...
