In vitro release of cefazolin in phosphate-buffered saline at pH 7.4, under 75 rpm agitation at 37 °C. (A) Cefazolin cumulative release for 3 µg, 15 µg, 30 µg, and 90 µg from 10% GelMA expressed as percentage of the encapsulation efficiency. (B) Cefazolin cumulative release for 30 µg from 5%, 10%, and 15% GelMA expressed as percentage of the encapsulation efficiency. (C) Cefazolin cumulative release for 3 µg, 15 µg, 30 µg, and 90 µg from 10% GelMA expressed in µg. (D) Cefazolin cumulative release for 30 µg from 5%, 10%, and 15% GelMA expressed in µg. (E) Cefazolin release rate per hour for 3 µg, 15 µg, 30 µg, and 90 µg from 10% GelMA expressed in µg/hour. (F) Cefazolin release rate per hour for 30 µg from 5%, 10%, and 15% GelMA expressed in µg/h. (G) Cefazolin maximum release rate at 1 h expressed in µg/h. Data are shown as mean ± standard deviation. The experiment was performed once with n = 6 technical replicates.
