Abstract
We synthesized hydrothermally water-soluble BP-CDs(Bisphosphonate-based carbon dots) using commercial osteoporosis medicines such as Alendronate, Zoledronate, Ibandronate and Risedronate. BPs are used for osteoporosis treatment clinically and are good candidates as a bone-imaging agent because of high affinity for hydroxyapatite. CDs were made from BP derivatives as the source of carbon and 1,2-ethylenediamine as the surface passivation agent. We confirmed that they exhibited the highest fluorescence intensity at 400nm and good photo stability. Due to superior biocompatibility, BP-CDs were imaging in living HeLa cells, which indicated that it is applicable in various fields of bioimaging. The high affinity of BP-CDs for hydroxyapatite also were verified through α-TCP(Tricalcium phosphate) scaffold incubated in BP-CDs solution.
As new fluorescent carbon material, advantages of BP-CDs include strong fluorescence, water solubility, low cytotoxicity and high affinity for hydroxyapatite. They are suitable candidates for the applications in the bioimaging field.
