BACKGROUND Gold nanoparticles are useful tools for biological applications due to their attractive physical and chemical properties. Their applications can be further expanded when they are functionalized with biological molecules. The biological molecules not only provide the interfaces for interactions between nanoparticles and biological environment, but also contribute their biological func...

محلول سیستئین به محلول حاوی نانوذرات نقره پایدارشده با پلی وینیل پیرولیدون و کاتیون باریم اضافه گردید. با اضافه کردن سیستئین انباشتگی نانوذرات نقره رخ داده و رنگ محلول کلوئیدی از زرد به صورتی تغییر پیدا می کند, و قله پیک پلاسمونیک نانوذرات نقره کلوئیدی در طول موج 397 نانومتر به سمت طول موج های بلندتر شیفت کرده و شاهد ظاهر شدن پیک جدیدی در طول موج 520 نانومتر خواهیم بود. در واقع کاتیون باریم نقش...

Nobel metal nanoparticles have drawn significant attention for a wide range of new applications in various fields including biology and medicine. Research work during the last two decades have clearly demonstrated that the properties of nanoparticles, in particular silver nanoparticles are strongly influenced by shape, size and size distribution, which is dictated by the synthetic method adopte...

In this brief review, gold nanoparticles conjugated with functional polymers are described from the viewpoint of application to sensing materials. The optical properties of gold nanoparticles, the synthesis of polymer-functionalized gold nanoparticles, and their analytical applications are discussed. Polymer-functionalized gold nanoparticles are categorized into two classes: biopolymer-conjugat...

A complex deposition process of high-temperature superconducting (HTS) thin films and coated conductors is usually optimized by concentrating on the crystalline quality material, thus getting best possible critical temperature self-field properties. However, most HTS power applications that are based act at high magnetic fields, an alternative approach focusing formation optimal network columna...

Recent advances in memristive nanocrystal assemblies leverage controllable colloidal chemistry to induce a broad range of defect-mediated electrochemical reactions, switching phenomena, and modulate active parameters. The sample geometry virtually all resistive studies involves thin film layers comprising monomodal diameter nanocrystals. Here we explore the evolution bipolar threshold across hi...
