In this study, an injectable self-healing multifunctional hydrogel (CMCGel) was developed based on dynamic cross‑linking between manganese ions (Mn<sup>2+</sup>) and carboxymethyl chitosan loaded with chlorella extract (CE). This platform implements an integrated “Remove<b>–</b>Remodel<b>–</b>Repair” (3R) strategy for comprehensive perioperative management. CMCGel exhibits distinctive pH/laser dual-responsive behavior: In the acidic tumor microenvironment, the accelerated release of CE and Mn<sup>2+</sup> enhances photodynamic therapy and chemodynamic therapy (CDT). This combination, activated by laser and gated by endogenous pH, achieves remarkable tumor suppression rates of 85.81% in vitro and 96.01% in vivo. As pH normalizes, Mn<sup>2+</sup> shifts from CDT to activate the cyclic GMP-AMP synthase stimulator of interferon genes (cGAS-STING) pathway, remodeling the immune microenvironment. Crucially, CMCGel’s adhesion strength in artificial pancreatic fluid at 48 h was 4703.80 ± 50.36 Pa, only 8.17% lower than that at 10 min. This enzyme-resistant property enables durable mechanical sealing at the fistula site, reducing amylase leakage by 55.71% and creating favorable conditions for tissue repair. By integrating pH/laser-triggered combination therapy, immunomodulation, and enzyme-resistant barrier functionality into a single platform, CMCGel presents a clinically promising strategy for perioperative management of pancreatic cancer.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02344-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148910546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review systematically identifies the multi-dimensional mechanisms of capacity degradation: including volume imbalance caused by transmembrane migration, inactivation and decomposition of active species, electrode degradation, and valence imbalance induced by side reactions. Targeting these challenges, the review deeply explores recovery strategies from physical repair to intelligent scheduling: covering the research and development of high-selectivity membranes, precise regulation of valence states, functionalized repair of electrodes, and model-driven predictive pathways integrating digital twins. Finally, current challenges such as characterization limitations and incomplete recovery rates are summarized, and future development directions for capacity recovery are envisioned. This review aims to provide a theoretical basis and technical guidance for extending the system cycle life of flow batteries and improving capacity recovery efficiency.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13547198/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148900013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing optoelectronic memristors often require electrical assistance or exhibit nonlinear and asymmetric conductance updates, limiting their energy efficiency and scalability. Herein, we report a spectrally partitioned all-optical memristor based on a PbS/PEDOT:PSS/VO<sub><i>x</i></sub> heterostructure, in which near-infrared and visible light are coupled to opposite defect-state filling and depletion pathways. Near-infrared illumination selectively excites PbS quantum dots and drives gradual electron transfer into oxygen-vacancy-related defect states in VO<sub><i>x</i></sub> through the PEDOT:PSS-regulated interface, producing continuous conductance potentiation. By contrast, visible illumination activates VO<sub><i>x</i></sub> and promotes interfacial hole-assisted recombination, leading to reversible depletion of defect-state electrons and conductance depression. This wavelength-selective carrier-transfer process enables highly linear and symmetric all-optical weight updates, achieving a linearity of 0.9994 and an effective 8-bit conductance resolution. The electrical energy consumption per optically induced synaptic event is calculated to be as low as 0.63 fJ under an ultralow probing bias. By integrating the devices into a 32 × 32 all-optically programmed array, we further demonstrate hardware-based BloodMNIST microscopic blood-cell image classification with an accuracy of 96.5% and strong noise robustness. These results provide a viable strategy for developing high-linearity, low-power, and spectrally programmable neuromorphic hardware.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"19 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13529625/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148863294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
