Rosmarinic acid determination using biomimetic sensor based on purple acid phosphatase mimetic

“…These qualities were attributed to the excellent stability of the Fe(III)Zn(II) complex employed to mimic the active site of the enzyme purple acid phosphatase. In addition, this sensor shows better analytical performance compared with other biosensors and sensors reported in the literature [17][18][19][20][21]34]. …”

“…In recent years our group has described in the literature the construction and application of several biosensors and biomimetic sensors based on a carbon paste (CP) [17][18][19][20][21]. Three types of carbon paste electrodes were constructed: one with and one without the Fe(III)Zn(II) complex, and another modified with Fe(III) and Zn(II) perchlorate.…”

“…Also, they do not require substantial sample preparation and facilitate analysis in mixtures and complex matrices. Furthermore, the coupling of electrochemical methods with the intrinsic selectivity and sensitivity of our enzymatic mimetic catalyst reactions is promising for the construction of a lowcost and simple biomimetic sensor [17][18][19][20][21].…”

O biopolímero quitosana, modificado quimicamente ou reticulado com metais, em forma de pó ou esfera, aplicado no estudo termiquímico da interação com cobre e aminas alifáticas

“…A cadeia da quitosana admite um grande número de modificações químicas através dos diferentes grupamentos funcionais distribuídos sobre o anel glicopiranosídeo. A estrutura macromolecular pode ser manipulada, mediante a introdução de novos grupos funcionais de interesse, para conferir aos derivados, características que atendam às aplicações finais [79][80][81][82].…”
