Porous egg microparticles for controllable drug delivery and oncotherapy

Baicalein (BAI) extracted from Chinese herb has been proved to increase the sensitivity of tumor cells to gemcitabine (GEM) and effectively solve the problem of drug resistance of tumor cells. Nevertheless, intravenous administration often leads to intolerance of patients and side effects. In this paper, we introduced egg‐based porous microparticles for controllable drug delivery and oncotherapy, which avoided frequent intravenous administration. The interconnected porous structure endowed the microparticles with the capacity of loading sufficient drugs and releasing in a controllable way by adjusting the concentration and proportion of egg white and yolk. We have demonstrated that the cell viability of drug delivery system group was less than 50%, while the single drug group was more than 70%, which indicated that the co‐delivery of GEM and BAI could significantly reduce the proliferation of cells. These features indicated that the egg porous microparticles are ideal for controllable drug delivery and oncotherapy.
