Enhanced Corneal Penetration and Therapeutic Efficacy of CQD-Mediated Antibacterial Delivery

The presence of a positive charge on CQD enables it to effectively overcome the membrane barriers of corneal epithelium, thereby significantly enhancing the efficacy of treatment in stromal conditions. This is particularly crucial due to the limited penetration ability of antibacterial reagents through the cornea, thus highlighting the potential of CQD as a promising solution for improving therapeutic outcomes.
