Poly(lactic-co-glycolide) based biodegradable electrically and magnetically act...
Hermenegildo, B.; Meira, Rafaela Marques; Correia, Daniela Maria Silva; Díez, A. G.; Ribeiro, Sylvie Oliveira; Serra, J. P.; Ribeiro C.Polymer scaffolds are playing an increasing role in tissue engineering (TE), although there is still a need to improve their biomimicry of cellular microenvironments, by having smart scaffolds with an active response, which can improve tissue regeneration. This work reports on the novel combination of poly(lactic-co-glycolide) (PLGA) with the ionic liquid (IL) choline bis(trifluoromethylsulfonyl)imide ([Chol][T...
Chiral drug analysis in forensic chemistry: An overview
Ribeiro C.; Santos C.; Gonçalves V.; Ramos A.; Afonso C.; Tiritan M.E.Many substances of forensic interest are chiral and available either as racemates or pure enantiomers. Application of chiral analysis in biological samples can be useful for the determination of legal or illicit drugs consumption or interpretation of unexpected toxicological effects. Chiral substances can also be found in environmental samples and revealed to be useful for determination of community drug usage ...
Assessment of Douro and Ave River (Portugal) lower basin water quality focusing...
Couto C.M.C.M.; Ribeiro C.; Maia A.; Santos M.; Tiritan M.E.; Ribeiro A.R.; Pinto E.; Almeida A.Water quality of Douro and Ave lower basin was evaluated regarding physicochemical parameters (pH, conductivity, dissolved oxygen and temperature), nutrient compounds (nitrates, nitrites, ammonium and orthophosphates), chlorophyll a and occurrence of trace elements (Li, Be, Al, Ti, V, Cr, Co, Ni, Cu, Zn, Se, Mo, Ag, Cd, Sb, Ba, Tl, Pb, Th and U). To study spatiotemporal variations and possible anthropogenic sou...
Occurrence of chiral bioactive compounds in the aquatic environment: A review
Ribeiro C.; Ribeiro A.R.; Maia A.S.; Tiritan M.E.In recent decades, the presence of micropollutants in the environment has been extensively studied due to their high frequency of occurrence, persistence and possible adverse effects to exposed organisms. Concerning chiral micropollutants in the environment, enantiomers are frequently ignored and enantiomeric composition often neglected. However, enantioselective toxicity is well recognized, highlighting the ne...
