Abstract

An optically active antibacterial ruthenium(II) phenanthroline complex (tris(3,4,7,8-tetramethyl-1,10-phenanthroline) ruthenium(II) dichloride), is investigated for its potential as a multifunctional photo-initiator. Antibacterial and cytotoxic studies indicated that the complex is biologically active, and viable below <0.5 mm. The complex is shown to photo-polymerize gelatin using visible light in a similar manner to tris(2,2′-bipyridyl)ruthenium(II) dichloride and is demonstrated to retain antibacterial activity post-fabrication of a gelatin hydrogel. Incorporation of the photo-initiator into the interstitial fluid of a hybrid gelatin granular scaffold generated a multifunctional scaffold that retained cell viability and exhibited injectable properties.

钌三-双齿配合物作为多功能光引发剂的潜力

研究了一种具有光学活性的抗菌钌（II）菲罗啉配合物（三（3,4,7,8-四甲基-1,10-菲罗啉）二氯化钌）作为多功能光引发剂的潜力。抗菌和细胞毒性研究表明，该复合物具有生物活性，并在0.5 mm以下存活。该配合物与三（2,2′-联吡啶基）钌（II）二氯化物类似，在可见光下可光聚合明胶，并在明胶水凝胶制备后保持抗菌活性。将光引发剂掺入混合明胶颗粒支架的间质液中产生多功能支架，该支架保留了细胞活力并表现出可注射特性。
