The incidence of breast cancer has been increasing over the last four decades, although the mortality rate has decreased. Endocrine therapy and chemotherapy are the most used options for cancer treatment but several obstacles are still attributed to these therapies. Smart materials, such as nanocarriers for targeting, delivery and release of active ingredients, sensitive to intrinsic-stimuli (pH-responsive, redox-responsive, enzyme- responsive, and thermo-responsive) and extrinsic-stimuli (ultrasound-responsive, magnetic-responsive, light-responsive) have been studied as a novel strategy in breast cancer therapy.

This study aims to develop and characterize NCL loaded with ZnF16Pc (Pc) for application in antimicrobial photodynamic therapy. For the development of the NLC, the fusion-emulsification technique followed by sonication was applied. NLC and Pc-NLC were characterized in terms of mean diameter (Dm.

Also, these have shown to be phototoxic against several types of microorganisms and tumor cells. However, challenges such as low solubility in the physiological environment make its single administration unfeasible.
