A significant challenge in this domain is overcoming biological barriers and ensuring precise delivery to tumor sites. Immune cells, inherently adept at navigating the body’s defense systems and homing to tumor sites, present an excellent solution as Trojan horses for cancer nanotherapy. This review explores the utilization of immune cells as carriers or mediators of nanoparticle-based therapeutics. The Trojan horse strategy is presented in the context of nanomedicine and cancer, followed by a discussion of its advantages. Next, the diversity of nanoparticle systems that have shown positive therapeutic outcomes in preclinical studies is explored. The challenges of using immune cells as Trojan horses, such as nanoparticle loading and manipulation, are analyzed. Finally, strategies for fine-tuning nanoparticles to design an effective Trojan horse approach are suggested. By synthesizing current research findings, this review underscores the potential of nanotechnology in combination with immune cells for innovative and effective cancer treatments.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"156–171 156–171"},"PeriodicalIF":9.6,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsmaterialslett.4c01523","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143087071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the lack of material structure–property relationships and gas-sensing mechanisms has severely limited the rational design of gas-sensing materials. Herein, we try to understand how the electronic structure, d-band center, and atomic orbital bonding influence the gas adsorption energy, which exhibits a strong correlation with both the selectivity and sensitivity of gas-sensing materials. As a result, the lattice distortion induced by introducing heteroatoms prompts La atoms to actively participate in the gas adsorption process, which leads to the formation of multiatomic orbital hybridization bonds, significantly increasing the adsorption energy of ethanol and acetone molecules. This work illustrates that creating greater lattice distortion is an effective strategy to modulate the strength of gas adsorption, which is important for guiding the design and synthesis of metal-oxide semiconductor gas-sensing materials.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"149–155 149–155"},"PeriodicalIF":9.6,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143087320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the trade-off between the phosphorescence quantum yield (ΦPhos) and the phosphorescence lifetime (τPhos) highlights the necessity for developing new strategies to enhance RTP performance. While research often focuses on guest components in polymer-based host–guest RTP systems, the host materials, which provide rigid environments, are less explored. This work introduces a simple and efficient strategy to develop RTP materials with high efficiency and long lifetime by employing covalent cross-linking to modify the rigidity of the polymer matrix. By suppressing nonradiative decay and decreasing luminescence quenching under ambient conditions, not only the ΦPhos of cross-linked films is improved from 3.2% to 13.5%, but also the τPhos is extended from 482.34 to 625.23 ms. Thanks to its solution processability and water sensitivity, this RTP system was successfully applied in inkjet printing and binary anticounterfeiting.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"133–140 133–140"},"PeriodicalIF":9.6,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143087432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report spectrally stable and efficient pure-red light-emitting diodes (LEDs) realized through sequential ligand post-treatment of all-inorganic CsPbI3 PQDs. The as-synthesized CsPbI3 PQDs (∼4 nm) undergo sequential purification steps, employing trioctylphosphine oxide (TOPO) and guanidinium iodide (GUAI) as ligands. This approach preserves the size and structure of the CsPbI3 PQDs after two purification washes, improving the optoelectronic properties of CsPbI3 PQD films and enables a stable electroluminescent emission centered at 640 nm with an external quantum efficiency (EQE) peaking near 15%. Our sequential ligand post-treatment successfully prevents the aggregation and coarsening of PQDs, presenting a novel approach toward enhancing the stability and efficiency of PQD-based LED technologies.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 1","pages":"93–100 93–100"},"PeriodicalIF":9.6,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
