“…fig 3). Assuming a temperature gradient inside the heated tumors [12] and assuming different tumor temperatures lead to different DOX concentrations, bisecting the heated tumors in a lateral tumor half closer to the laser light applicator and a medial tumor half was considered as an internal control. The DOX data of the bisected tumors showed a trend to higher DOX concentration at higher temperatures.…”

“…So far, lysolipid-based TSL (LTSL) with encapsulated doxorubicin (DOX) has entered human clinical trials [6,7]. An improved TSL-formulation based on the synthetic phosphatidyldiglycerol (DPPG 2 -TSL) has been successfully developed [8,9] and investigated in animal models [8,[10][11][12]. Key features are improved serum stability when compared to LTSL and a comparably fast release rate at a temperature above 40°C [9,13,14] which is in the typical range (40°C-43°C) used in combined chemotherapy/HT tumor treatment concepts [15].…”

Compared with conventional tumor photothermal therapy (PTT), mildtemperature PTT brings less damage to normal tissues, but also tumor thermoresistance, introduced by the overexpressed heat shock protein (HSP). A high dose of HSP inhibitor during mild-temperature PTT might lead to toxic side effects. Glucose oxidase (GOx) consumes glucose, leading to adenosine triphosphate supply restriction and consequent HSP inhibition. Therefore, a combinational use of an HSP inhibitor and GOx not only enhances mildtemperature PTT but also minimizes the toxicity of the inhibitor. However, a GOx and HSP inhibitor-encapsulating nanostructure, designed for enhancing its mild-temperature tumor PTT efficiency, has not been reported. Thermosensitive GOx/indocyanine green/gambogic acid (GA) liposomes (GOIGLs) are reported to enhance the efficiency of mild-temperature PTT of tumors via synergistic inhibition of tumor HSP by the released GA and GOx, together with another enzyme-enhanced phototherapy effect. In vitro and in vivo results indicate that this strategy of tumor starvation and phototherapy significantly enhances mild-temperature tumor PTT efficiency. This strategy could inspire people to design more delicate platforms combining mildtemperature PTT with other therapeutic methods for more efficient cancer treatment.

Metal‐organic frameworks (MOFs) are an emerging class of synthetic materials obtained by combining organic and inorganic chemistry. MOFs show peculiar properties such as well‐defined crystalline structures, systematic structural variation, high porosity and the possibility to chemically functionalize the pores. These properties are especially promising for designing MOF nanoparticles (NPs) with special functions. The desired functions can be introduced and modified with a chemical approach, by the choice of the inorganic and organic building blocks. All these features and the highest surface area of any porous material make MOF NPs ideal for the use as nanocarrier in biomedicine. So far, a wide variety of biomedical applications of MOF NPs have been already envisioned being supported by promising first in vitro and in vivo results. The ongoing development of MOF NPs is at the edge of basic science to biomedical applications. A major focus of biomedical research is already in cancer therapy using MOF NPs as theranostic nanocarrier. In this article, NP designs and MRI‐labelling concepts are pointed out and discussed in the perspective of facilitating their translation to clinical use. Clinical application is envisioned with a major focus on theranostic MOF NPs and MRI as the most promising imaging method.
