Multifunctional surface materials that integrate passive radiative cooling (PRC) and flame retardant (FR) have emerged as promising solutions for enhancing both energy efficiency and fire safety. By synergistically combining PRC and FR functionalities, these materials can reflect solar radiation and emit heat to reduce surface temperatures, while simultaneously inhibiting ignition, slowing flame spread, and suppressing toxic smoke via gas-phase and condensed-phase mechanisms. This review presents a comprehensive overview of their working principles, performance evaluation methods, and material classifications of such materials, focusing on four main systems: organic polymer-based materials, polymer–inorganic composites, bio-based materials, and other material systems. Particular emphasis is placed on the relationship among materials, structure, and properties, strategies for integrating multifunctionality, and the influence of environmental conditions on long-term performance.

However, the lack of effective anti-Zika drugs makes the clinical application of symptom-relieving therapies the only available option. Recent progress in understanding virus–host interactions has significantly accelerated the development of innovative antiviral strategies against ZIKV infection. This review examines the challenges encountered in the development of anti-ZIKV drugs and explores potential therapeutic strategies through a novel ZIKV–host interaction perspective. Moreover, this review systematically outlines novel anti-ZIKV drug strategies, including promising molecular mechanisms and potential targets derived from ZIKV, replication-associated host factors, and immune system elements for drug design. Targeting ZIKV structural components to disrupt its life cycle remains a conventional antiviral strategy, while targeting replication-associated host factors and developing drugs that modulate host cellular processes represent promising therapeutic approaches. The frequently neglected antagonistic effect of ZIKV on innate host immunity and corresponding antiviral strategies are also examined in this review. More importantly, recent progress in antiviral strategies during pregnancy and anti-ZIKV drug delivery strategies are examined, with a focus on potential challenges and future directions for anti-Zika drugs. Further, regulating key placental blood barrier targets represents a promising therapeutic strategy against ZIKV during pregnancy. The progress of anti-ZIKV drug delivery systems enable maximum therapeutic efficacy. This review proposes an integration of potential intervention strategies from the perspective of ZIKV–host interactions, thereby aiming to establish a foundation for future anti-ZIKV research while accelerating the translation of anti-ZIKV therapeutics into clinical practice.</div></div>","PeriodicalId":395,"journal":{"name":"Nano Today","volume":"66 ","pages":"Article 102902"},"PeriodicalIF":10.9,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
