This composite aims to trigger an anticancer response through sequential PDT and chemotherapy. The nanocomposite exhibited high stability in a physiological environment with a pH of 7.4. It was also able to release DO8 continuously in an acidic environment with a pH of 5, which shows that it can adapt to the conditions in the tumor microenvironment. The MIL-101(Fe)MOF-FA@DO8 nanoparticles (NPs) with 30% and 50% DO8 have been studied <i>in vitro</i> under different conditions (light and dark) and have been shown to be compatible with living tissues and specifically target HepG-2 cells. The IC₅₀ values of 50% DO8 and 30% DO8 loaded MOF-FA were found to be 88.67 and 105.9 μg mL^-1 under dark conditions, respectively. Under light conditions, they demonstrated the highest efficacy in inhibiting tumor cell growth. The IC₅₀ values were found to be 8.94 and 11.78 μg mL^-1. Flow cytometry analysis of annexin V/PI-stained apoptotic and necrotic cells in HepG-2 cells treated with the modified MIL-101-FA@50% DO8 NPs at IC₅₀ doses under both dark and light conditions indicates that the primary mechanism of cell death is necrosis, likely due to the enhanced formation of reactive oxygen species (ROS) under light conditions compared to that under dark conditions. This increased reactive oxygen species (ROS) generation leads to extensive membrane rupture, resulting in significant cell damage after treatment with the modified MIL-101-FA@50% DO8 NPs.

Nonetheless, the efficacy of CDT is constrained by the limited availability of catalyst ions capable of decomposing pre-existing intracellular H₂O₂ and generating reactive oxygen species (ROS) necessary to achieve a therapeutic response. To address these limitations, a tailored strategy has been developed to enhance the efficacy of Fenton-like reactions to eradicate selectively cancer cells. This innovative approach involves the utilization of dual metal cations (Zn²⁺, Fe²⁺) within zinc nitroprusside (ZnNP) material. Remarkably, this method takes advantage of the acidic conditions prevalent in tumors, thus eliminating the need for external stimuli. Through these advancements, the tailored approach exhibits the potential to specifically target and eliminate cancer cells, overcoming the mentioned limitations. A simple mixing technique was utilized to synthesize ZnNP, which was structurally and morphologically characterized. Furthermore, extensive <i>in vitro</i> investigations were conducted to assess its anti-tumoral mechanism of action. ZnNP exhibits a remarkable capability to increase intracellular H₂O₂ within cells. This process leads to the generation of various reactive species, including hydroxyl (˙OH) and superoxide (O₂˙^-) radicals, and peroxynitrite (ONOO^-), which act as apoptotic inducers specifically targeting cancer cells. Cellular uptake studies have shown that ZnNP enters the lysosomes, evades degradation, and takes advantage of their acidic pH environment to significantly increase the production of ROS. These findings are further supported by the activation of multiple oxidative genes. Furthermore, the biocompatibility of ZnNP has been demonstrated in <i>ex vivo</i> models using healthy liver cells. Notably, ZnNP exhibited therapeutic effectiveness in high-grade serous ovarian cancer (HGSOC) patient-derived tumor organoids (PDTO), further confirming its potential as a therapeutic agent. The present study highlights the therapeutic potential of ZnNP as a generator of multiple ROS <i>via</i> a Fenton-like reaction. This research offers a promising therapeutic approach for CDT application in combatting HGSOC, a highly aggressive and life-threatening cancer.</p>","PeriodicalId":65,"journal":{"name":"Biomaterials Science","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various factors contribute to tumor resistance to immunotherapy, among which tumor-associated macrophages (TAMs) are critical regulators of tumor sensitivity. Therefore, combining cancer immunotherapies with drug delivery systems (DDSs) targeting TAMs has become an intriguing treatment strategy. However, the target molecules used in DDSs are limited to a few receptors expressed on TAMs. Therefore, the identification of novel target molecules for TAM-specific DDS is urgently needed. The current study evaluated the ability of a cholesteryl pullulan (CHP) nanogel to target TAMs <i>via</i> mDC-SIGN (CD209b).

However, current protocols for integrating microscale topographical features in extracellular matrix hydrogels require expensive microfabrication equipment and multi-step procedures involving error-prone manual handling steps. To address this challenge, we present STAMP (simple templating of actuators <i>via</i> micro-topographical patterning), an easily accessible and cost-effective one-step method to pattern microtopography of various sizes and configurations on the surface of hydrogels using reusable 3D printed stamps. We demonstrate that STAMP enables precisely controlling the alignment of mouse and human skeletal muscle fibers without negatively impacting their maturation or function. To showcase the versatility of our technique, we designed a planar soft robot inspired by the iris, which leverages spatially segregated regions of concentric and radial muscle fibers to control pupil dilation. Optogenetic skeletal muscle fibers grown on a STAMPed iris substrates formed a multi-oriented actuator, and selective light stimulation of the radial and concentric fibers was used to control the function of the iris, including pupil constriction.

The prevention strategies for oligomer formation could be therapeutic in treating PD. Various conventional strategies have been developed for the management of PD. However, their clinical applications are limited due to toxicity, off-targeting, side effects, and poor bioavailability. Recently, nanomaterials have gained significant attention due to unique physicochemical characteristics such as nanoscale size, large surface area, flexibility of functionalization, and ability to protect and control a loaded payload. Functionalizing the surface of nanoparticles with a desired targeting agent could offer targeted delivery of the payload at the site of action due to specificity and selectivity against complementary molecules. Among various functionalization approaches, biomolecule-functionalized nanomaterials offer benefits such as enhanced bioavailability, improved internalization into target cells through receptor-mediated endocytosis, and delivery of therapeutics across the BBB (blood-brain barrier).
