These dendrimers efficiently load various drugs through electrostatic interactions, covalent bonding, or encapsulation, owing to their high density of terminal amine groups. However, the inherent cationic nature of PAMAM dendrimers can lead to cytotoxicity and limited systemic circulation due to interactions with negatively charged biomolecules. To address these limitations, surface modification strategies have been developed to enhance targeting, trigger controlled drug release, and decrease cytotoxicity. This review critically examines recent advancements in engineering PAMAM dendrimers for improved drug delivery, focusing on strategies to increase drug loading capacity, achieve tissue-specific targeting, reduce toxicity, and enable stimuli-responsive release.

The addition of 0.5 wt.% of carbon nanoplatelets showed a viscosity drop of 16.6 %. This reduction in viscosity creates a smaller boundary layer, resulting in enhanced heat transfer and better performance.

Achievements in nanoscale analysis and nanofabrication have facilitated practical applications across a range of fields, including nanoelectronics, nanofluidics, drug delivery, optical and plasmonic devices, and biosensing. Nonetheless, conventional top-down fabrication techniques, such as electron beam lithography, focused ion beam lithography, soft lithography, and nanoimprint lithography, are frequently constrained by factors such as cost, scalability, and manufacturing complexity. Scanning Probe-based Lithography (SPL) has recently emerged as a promising alternative, offering precise nanostructure fabrication and immediate characterization in ambient conditions. This paper focuses on Raster-Atomic Force nanolithography (R-AFL), highlighting its capability for fabricating 3D nanostructures on Polymethyl methacrylate (PMMA) with minimal process steps. By coupling this technique with a simple wet etching process using Methyl Isobutyl Ketone (MIBK) and 2-propanol (IPA), enhanced resolution and quality of the nanostructure are achieved. Furthermore, the nanostructures are successfully transferred to a Silicon Nitride (Si<sub>x</sub>N<sub>y</sub>) substrate via plasma etching, demonstrating the versatility of the approach. This combination of AFM-based lithography, wet etching, and plasma transfer represents an innovative and efficient method for creating nanopatterned surfaces on both soft and hard substrates, addressing key limitations of conventional nanofabrication techniques.</div></div>","PeriodicalId":100942,"journal":{"name":"Nano Trends","volume":"9 ","pages":"Article 100088"},"PeriodicalIF":0.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
