Summary: For patients with refractory breast cancer, integrative immunotherapies are becoming crucial in treatment. However, many patients do not respond to treatment or relapse. The tumor microenvironment and cancer stem cells play important roles in the progression of breast cancer. Modulating the immune system and targeting breast cancer stem cells directly are essential strategies for improving therapeutic efficacy.

Summary: This research explores the use of graphene nanomaterials as carriers for bee venom component melittin (M) to target breast cancer cells. The results indicate that M complexes with nanomaterials can effectively reduce oxidative stress levels compared to M alone, but using graphene as the carrier causes more severe DNA damage. Moreover, the use of M and graphene complex shows a greater inhibitory effect on tumor progression than a complex with graphene oxide.

Summary: Brain metastases from breast cancer are difficult to surgically remove and have limited drug treatment options due to their growth patterns and the blood-brain barrier. By assembling prodrug-loaded nanoparticles that target both the BBB and metastatic breast cancer, researchers were able to significantly extend the survival time of mice with intracranial metastatic breast cancer, suggesting a potential important direction for drug therapy against brain metastases.

Summary: Nanoparticle drug formulations have advantages in cancer therapy, but the assessment of new drugs is limited by preclinical models. This study demonstrates a new approach to test nanomedicine using a microtumor array formed through hydrogel micropatterning. It allows simultaneous evaluation of drug uptake and efficacy in different cancer cell fractions with high reproducibility. The findings suggest that nanoparticle drug formulations are well suited for targeting the stem cell-like population in cancer therapy due to their relationship with drug resistance, recurrence, and metastasis.

Summary: Piezocatalysis is capable of converting mechanical energy into chemical potential, driving redox reactions using physical force. In this study, we demonstrate that piezoelectric BaTiO3 nanoparticles in the solid state can generate reactive hydroxyl radicals (·OH) by transducing mechanical load, leading to the initiation of solid state free radical polymerization. Chemisorbed water on the surface of BaTiO3 nanoparticles plays a crucial role by being oxidized to (·OH) via mechanoredox catalysis. This force-induced radical production in dry piezoelectric materials offers a promising new approach for harnessing mechanical energy in solid state radical synthesis.

Summary: Surface engineering of MOF NPs using dynamic modification strategies enables the tailoring of PEG-grafted MOF NPs with improved colloidal stability and high dispersity, while maintaining their morphology and lattice crystallinity. The PEG-grafted MOF NPs show reduced adsorption of HSA protein compared to uncoated ones, indicating the potential for reducing nonspecific interactions and introducing targeting moieties for specific interactions. This approach expands the applications of colloidal MOF NPs in biologically relevant fields.

Summary: This study found that drug loading has an impact on cellular uptake of nanoparticles, which has been overlooked in previous studies focusing on properties such as shape and size. With increasing drug loading content, there was greater dehydration of the polymer shell, leading to increased protein adsorption and particle aggregation. The nanoparticle with the highest drug loading content showed reduced cellular uptake and toxicity in various cell lines. It was concluded that an intermediate drug loading content allows for sufficient cellular uptake and toxic drug concentration.

Summary: Trehalose glycopolymers have been extensively studied recently and have shown some unique properties. In order to compare their properties, researchers synthesized structurally similar glycopolymers composed of trehalose and sucrose. These glycopolymers have very low content of non-saccharide structural fragments, making their properties strongly influenced by the saccharide moieties. The study comprehensively characterized the glycopolymers, including their tendency to self-assemble, hydrolytic stabilities at different pH, and susceptibility to enzymatic hydrolysis.
