“…Daou et al [12] have shown that the average size of the coated nanocrystals increases with the increase of the PEG molecular weight in a linear fashion up to 12 000 Da, before reaching a plateau for 22 000 Da. On the other hand, Ren et al [13] have shown that with the increase of the PEG molecular weight, the hydrophilicity of a synthesized copolymer enhances, which leads to a smaller interfacial tension between the polymer solution and water and gives rise to a smaller particle size.…”

“…O pico em 1,63 ppm está relacionado com os prótons de grupos metila situados entre os dois anéis aromáticos da resina epóxi, enquanto que os picos agrupados na faixa entre 6,80 e 7,28 ppm são referentes aos prótons aromáticos. Os grupos glicidílicos terminais são responsáveis pelo aparecimento dos picos situados no intervalo de 2,6 a 4,3 ppm [19] , enquanto o forte pico ao redor de 3,65 ppm está relacionado aos grupos metilênicos (-CH 2 -) do PEG [20,21] . O pico em 7,28 ppm é referente ao próton do clorofórmio, usado como solvente.…”

“…A existência de ligação covalente entre DGEBA e PEG é evidente pelo aparecimento de um multiplete de baixa intensidade ao redor de 4,2 ppm, que representa os prótons metilênicos das unidades terminais aciladas (-CH 2 -O-CO-) das cadeias de PEG [21] . Uma outra alteração importante nos espectros de RMN-1 H com o tempo de reação é o deslocamento do dublete referente aos grupos glicidílicos da resina epóxi, em 2,89 ppm.…”

“…[13,14 ] solid-phase extraction and targeted drug delivery. [15][16][17][18][19] magnetic micro particles have good chemical stability, biocompatibility and biodegradability, which makes them safe in the clinical applications, so they also are used for MRI. [20,22] and targeting drug delivery.…”
