Abstract The synthesis of magnetite nanoparticles (Fe₃O₄ NPs) has gained significant interest due to their broad applications, particularly in biomedicine and environmental purification. In this study, Fe₃O₄ NPs are synthesized using a novel chemical co‐precipitation method, yielding with excellent characteristics such as saturation magnetization 41.42 emu g −1 , coercivity less than 4 Oe, remanence below 0.4 demonstrating superparamagnetic‐like properties. particles achieved an average size 11 nm displayed robust colloidal stability aqueous suspension for ≈30 days. Additionally, chitosan‐coated (Fe₃O₄‐CS) prepared, which maintained similar magnetic properties slightly lower 38.35 the nonmagnetic CS layer. To assess biomedical applicability these NPs, effects on model proteins human serum albumin lysozyme examined. Circular dichroism studies revealed only slight decreases α‐helix content indicating minimal alterations secondary structure. Moreover, fluorescence indicated local changes protein tertiary structures without disruption. This research highlights potential Fe₃O₄‐CS applications drug delivery controlled release systems stability, biocompatibility, unique

The next step in nanotechnology is to establish a methodology assemble new functional materials based on the knowledge of nanotechnology. This task undertaken by nanoarchitectonics. In nanoarchitectonics, we architect material systems from nanounits such as atoms, molecules, and nanomaterials. terms hierarchy structure harmonization function, created nanoarchitectonics has similar characteristics organization biosystems. Looking at actual biofunctional systems, dynamic properties interfacial environments are key. other words, interfaces important for production bio-like highly systems. this review paper, will be discussed, looking recent typical examples. particular, basic topics “molecular manipulation, arrangement, assembly” “material production” discussed first two sections. Then, following section, “fullerene assembly: zero-dimensional unit advanced materials”, discuss how various structures can very nanounit, fullerene. above examples demonstrate versatile possibilities architectonics interfaces. last these tendencies summarized, future directions discussed.

Nanoparticles have been widely used in cancer diagnostics and treatment research due to their unique properties. Magnetic nanoparticles are popular imaging techniques ability alter the magnetization field around them. Plasmonic mainly applied treatments like photothermal therapy convert light into heat. While these among respective fields, magnetic–plasmonic core–shell (MPNPs) gained popularity recent years combined magnetic optical properties from core shell. MPNPs stood out theranostics as a multimodal platform capable of serving contrast agent for imaging, guidable drug carrier, causing cellular ablation through energy conversion. In this review, we summarize different most common synthesis approaches. We particularly discuss applications diagnosis based on mechanisms using particles. Lastly, look current challenges they face clinical future perspectives detection therapy.

Abstract Iron oxide nanoparticles are inexpensive materials that environmentally friendly and have properties render them suitable for wide range of applications. A facile time-effective coprecipitation method was used to prepare iron in a 1:1 molar ratio Fe 2+ 3+ ions solution. obtained at 18 60 °C yielded spherical magnetite with particle sizes 7.63 8.5 nm respectively while comprising mixture hematite nanorods, mean width 9.5 length 75 were 90 °C. synthesized energy band gap 4.16 eV those the same 4.66 eV. Precursor concentrations 0.042, 0.08 0.0126 M 7.94, size increased increasing concentration. Magnetite 0.126 optical gaps 4.65, 4.88 5.19 respectively.

It has become clear that superior material functions are derived from precisely controlled nanostructures. This been greatly accelerated by the development of nanotechnology. The next step is to assemble materials with knowledge their nano-level structures. task assigned post-nanotechnology concept nanoarchitectonics. However, nanoarchitectonics, which creates intricate three-dimensional functional structures, not always easy. Two-dimensional nanoarchitectonics based on reactions and arrangements at surface may be an easier target tackle. A better methodology would define a two-dimensional structure then develop it into function. According these backgrounds, this review paper organized as follows. introduction followed summary three issues; (i) 2D 3D dynamic control: liquid crystal commanded surface, (ii) rational construction: metal-organic framework (MOF) covalent organic (COF); (iii) amplification: cells regulated surface. In addition, summarizes important aspects ultimate perspective. goal establish integrated creation reconsidering various reported cases viewpoint where can regarded method for everything in science.
