Here, we report a nuclease-resistant, L-DNA-based Förster resonance energy transfer (FRET) probe that directly detects radiation-induced DNA strand cleavage. The probes consist of short single-stranded L-DNA labeled with FAM and TAMRA fluorophores, designed to lose FRET upon strand scission. Both two- and six-thymidine variants (L-T2 and L-T6) were synthesized and shown to resist enzymatic degradation while maintaining fluorescence under irradiation up to 50 Gy. Radiation exposure induces a dose-dependent increase in donor fluorescence, with L-T2 exhibiting greater sensitivity in physiological buffer. The probes are quantitatively responsive, with detectable signal shifts from as little as 1% cleavage and a linear relationship between donor/acceptor emission ratios and DNA breakage. In cells, however, the behavior is more complex. While L-T6 exhibits dose-dependent FRET loss in certain contexts, particularly in radiation-sensitive SKBR3 cells, the extent of cleavage is significantly reduced compared to <i>in vitro</i> conditions. Glutathione depletion failed to enhance intracellular cleavage, suggesting that other mechanisms of protection or sequestration are at play. These findings highlight the challenges of sensing strand scission in the cytoplasm and point to unanticipated barriers to detecting radiation-induced damage in living cells.</p>","PeriodicalId":94089,"journal":{"name":"Journal of materials chemistry.

However, this balance can be disrupted, leading to susceptibility to microbial invasion and inflammatory disorders. Conventional oral healthcare materials often fall short in providing sustained therapeutic benefits locally. To address this challenge, researchers combine various bioactive materials with polymer networks designed for wet-adhesion, tailored to the unique conditions of the oral cavity. This review outlines key design strategies for achieving stable wet adhesion, including eliminating interfacial water, establishing robust interfacial linkages, and enhancing material cohesion. Building on interfacial stability, this review further discusses the three dominant strategies for integrating bioactivities, such as antimicrobial, anti-inflammatory, and osteogenic activities, emphasizing the synergistic interplay of bioactivity and wet adhesive performance.

This leads to deposition of fibrillar Aβ (fAβ), contributing to AD progression. Microglia, the brain's resident immune cells, are central to the phagocytotic-fusion of fAβ. Notably, fAβ itself can activate microglia <i>via</i> toll-like receptor signaling, triggering a phagocytic response. Previous studies have shown that activated microglia exhibit efficient phagocytotic-fusion of fAβ, primarily through lysosomal acidification compared to resting microglia. Therefore, distinguishing microglial activation states is vital for understanding and potentially modulating Aβ clearance mechanisms in AD. Herein, we systematically modified the structure to develop fluorescent probes (FPs), PS-Mor and PM-DMor based on morpholine-conjugated pyrylium and pyridinium derivatives of indigenous \"IndiFluors\". These probes exhibit strong fluorescence enhancement in lysosomal pH windows by modulating photoinduced electron transfer (PET). The turn-on behavior of the probes was further supported by TD-DFT/PCM theoretical calculations. Confocal imaging revealed that PM-DMor selectively localizes to lysosomes, while PS-Mor targets mitochondria in activated human microglia. PM-DMor effectively monitors intracellular pH changes (ΔpHi) during drug-induced apoptosis and discriminates activated from resting microglial using both fluorescence microscopy and flow cytometry. Importantly, PM-DMor also tracks Aβ-induced microglial activation and subsequent phagocytosis of Aβ. Overall, PM-DMor offers a valuable tool for probing lysosomal dynamics in microglia and holds promise for early-stage therapeutic strategies targeting Aβ clearance in Alzheimer's disease.</p>","PeriodicalId":94089,"journal":{"name":"Journal of materials chemistry.

The oxidative drug therapy combining arsenic trioxide (ATO) and D-vitamin C (D-VC) has demonstrated promising efficacy by targeting mitochondrial functions and depleting antioxidant defences to induce apoptosis in CRC cells. ATO and D-VC create a hostile environment for cancer cells by simultaneously targeting mitochondrial metabolism and redox homeostasis, reducing their ability to adapt and survive. This study evaluated the cytotoxic effects of ATO/D-VC in 2D cell cultures and 3D cell models, known as clusteroids, generated from CRC cell lines HCT116 and SW620. In the 2D cultures, the ATO/D-VC combination significantly reduced cell proliferation to 40-60% and viability to below 30% of control levels. In contrast, clusteroids showed a more limited response, with proliferation reduced to 60-80% and viability to 80-90%, highlighting the impact of the extracellular matrix (ECM) and cell-cell interactions in limiting drug diffusion within structured tumour microenvironments. To overcome these drug diffusion barriers, ATO and D-VC were individually encapsulated in poloxamer-stabilized shellac-based nanoparticles (NPs) surface functionalized with Savinase, a protease known to degrade ECM components. The cell viability and cell proliferation assays demonstrated that nanoparticle-mediated delivery significantly enhanced treatment efficacy in clusteroids. Dual treatment of Savinase-coated ATO and D-VC loaded NPs caused pronounced disruption of clusteroid morphology and substantially reduced both viability and proliferation to approximately 30-40% of untreated control levels. Compared to the free drug and uncoated nanoparticle formulations, the Savinase-functionalized nanoparticle formulation achieved nearly twice the reduction in viability and proliferation, indicating a marked improvement in therapeutic effect. Unloaded Savinase-coated nanoparticles showed minimal impact, underscoring their biocompatibility. This approach demonstrates the potential of protease-functionalized nanoparticles to enhance the oxidative drug delivery and efficacy in CRC tumours and could potentially allow targeting the therapeutic resistance in other solid tumours with dense ECM barriers.</p>","PeriodicalId":94089,"journal":{"name":"Journal of materials chemistry.
