Ionically cross-linked micro-sized hydrogels with encapsulated drug: Structure, cell uptake kinetics and cytotoxicity

[Display omitted] Micro-sized hydrogels synthesized by electrostatic cross-linking of anionic alginate with Ca2+ cations were additionally loaded with cationic fluorescent dye Rhodamine 6B or cationic antitumor antibiotic doxorubicin. Forming complexes with Ca2+ alginate hydrogels, doxorubicin retai...

More Information
Summary:[Display omitted] Micro-sized hydrogels synthesized by electrostatic cross-linking of anionic alginate with Ca2+ cations were additionally loaded with cationic fluorescent dye Rhodamine 6B or cationic antitumor antibiotic doxorubicin. Forming complexes with Ca2+ alginate hydrogels, doxorubicin retained or even reduced its toxicity to tumor and normal cells. The results can be used to design containers for the encapsulation and delivery of drugs and control their interaction with cells.
