However, an ongoing challenge is the efficient and targeted delivery of RNA to specific cells while minimizing toxicity and off-target effects. This review examines recent advancements in nanoparticle( s) (NPs) delivery systems, with a focus on RNA-coated liposomes, lipid nanoparticles (LNPs), and size- and surface-modifiable NPs, aiming to overcome the challenges associated with RNA delivery. We also explore the impact of specific patents in this field. The relevant information was collected from the scientific literature. We discussed various NP platforms and their applications, such as RNA-coated liposomes for oral cancer treatment, dry powder formulations of mRNA-loaded LNPs for pulmonary delivery, and LNP-mediated siRNA delivery for respiratory infections. We also explore NP optimization strategies, such as lipid tail modifications for RNA cargos like mRNA and CRISPR/Cas9. These NP-based systems have led to advancements in tumor targeting, intracellular delivery, and RNA release, demonstrating their promise in RNA therapeutics. Relevant patents, such as WO2016044478A1, which details the use of AAV vectors for treating MYOC glaucoma with RNAi targeting MYOC; WO2011158933A1, which describes a siRNA-based pharmaceutical composition for renal fibrosis using liposomes with retinol as a targeting agent; and WO2019173787A1, which specifies bacterial-toxin-derived constructs for oral siRNA delivery, further validate the progress in RNA delivery technologies. Despite these advancements, challenges such as targeting efficiency, endosomal escape, stability, immune system interactions, and scalability still remain. Continued innovation in RNA nanotechnology, drawing on insights from recent patents, is crucial for developing more effective and personalized RNA-based therapies.","PeriodicalId":49324,"journal":{"name":"Recent Patents on Nanotechnology","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145294177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Green Revolution introduced new biotic and abiotic stresses, posing significant challenges. Protected cultivation minimizes stress by providing a regulated environment. The growing demand for food requires us to consider protected farming. Greenhouses are the most effective solution for protected horticulture. Protected production of high-value vegetables has shown remarkable promise over the past decade. Protected cultivation offers hitherto untapped opportunities in agriculture with the advancement of technology and a liberalized economy. These technologies benefit both large-scale producers and those with smaller landholdings, as increased production levels remain economically relevant to agriculture. Protected cultivation is a precise, progressive, and parallel approach to agriculture that considers technological aspects, grower needs, and market economics. Flowers are becoming popular as a means of celebrating special occasions. India's protected flower industry has led to an increase in commercial flower exports. The meet the demand, floriculture crops like roses, gerbera, carnations, lilies, etc., are grown in protected structures.

Neuromorphic engineering and brain-inspired electronics take inspiration from biological information pathways in neural assemblies, particularly their fundamental building blocks and organizational principles. In contrast, resistive switching in memristive devices is widely considered an electronic synapse with potential applications in in-memory computing and vector-matrix multiplication. Further aspects of brain-inspired electronics require exploring both organizational principles from individual building units towards connected networks, as well as the resistive switching properties of each unit. In this context, nanogranular matter made of nano-objects, such as nanoparticles or nanowires, has gained considerable research interest due to emergent brain-like, scale-free switching dynamics originating from the self-organization of its building units into connected networks. In this study, we review resistive switching in nanogranular matter featuring metal nanoparticles as their functional building blocks. First, common deposition strategies for nanoparticles, as well as nanoparticle-based nanocomposites, are discussed, and challenges in the investigation of their inherited resistive switching properties are addressed. Secondly, an overview of resistive switching properties in nanogranular matter, ranging from individual nanoparticles over sparse nanoparticle arrangements to highly interconnected nanogranular networks, is provided. Finally, concepts and examples of information processing using nanoparticle networks are outlined.","PeriodicalId":49324,"journal":{"name":"Recent Patents on Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144576722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
