Multifunctional nanomaterials with photodynamic and sonodynamic properties have attracted wide attention in tumor therapy, but the design and preparation of “all-in-one” type of multifunctional nanomaterials with single component remains challenging. Herein the “all-in-one” type of Zr-PpIX (protoporphyrin IX) coordination nanoparticles (ZrPs) with photodynamic and sonodynamic properties was reported as efficient nano-photo/sonosensitizers. The ZrPs had an average size of about 50 nm. The survey X-ray photoelectron spectroscopy (XPS) spectrum showed strong Zr, C, N and O elemental signals, verifying that the ZrPs were composed of Zr/C/N/O elements. In addition, Fourier transform infrared (FTIR) spectra, ultraviolet-visible (UV-Vis) spectra and fluorescence (FL) spectra showed that the Zr4+ ion was only coordinated with the carboxyl group of PpIX. The ZrPs contained photo/sono-sensitizers PpIX, which could be excited by light/ultrasonic (US) to transform O2 into cytotoxic 1O2. Furthermore, the 1O2 can be detected by using 1,3-diphenylisobenzofuran (DPBF) assay. When the mixed solution (ZrPs+DPBF) was excited by light, the peak of DPBF decreased rapidly as the light irradiation time increased, which suggested the generation of 1O2 by ZrPs+light. Similarly, the absorbance of DPBF+ZrPs was reduced as the US time increased, which confirmed the sonodynamic effect of ZrPs+US. After 5 min of light/US irradiation, 59.7% (light) and 22.8% (US) of DPBF was found to be oxidized by ZrPs, which showed effective ROS generation for photodynamic/sonodynamic therapy. Besides, ZrPs had shown good biosafety in vitro cellular experiments. ZrPs can be effectively endocytosed/uptaken by tumor cells. Meanwhile, ZrPs within cells can generate ROS upon light/US, affording photodynamic and/or sonodynamic effects. After 5 min of ZrPs with light/US irradiation, the cell viability goes down rapidly from about 100% to 5.3%. Therefore, the present study not only represents ZrPs as an “all-in-one” type of multifunctional nanomaterials for PDT-SDT therapy, but also provides some insights for designing other PpIX-related molecules with the similar structure for bioapplication.
