Water soluble colloidal nanoparticles possess huge surface negative charge and this provides their colloidal stability [1]. The surface charge, therefore, ultimately demonstrate the overall behavior of the nanoparticles irrespective of core material. We demonstrate fluorescence based dual emission polarity sensor that is based upon hydroxyflavone derivative [2]. The NH2 group at position 7 faci...

Here, for the first time, a hybrid catalyst in which hemin and gold nanoparticles are positioned in spatially separate domains within a graphene–mesoporous silica support is presented. Specifically, monomeric hemin can be anchored on the inner exposed graphene surface of a graphene–mesoporous silica hybrid (GS) via p–p stacking interactions. After the assembly, such nanocomposites can function ...

We present an efficient approach to develop cellulose nanocrystal (CNC) hybrids with magnetically responsive Fe3O4 nanoparticles that were synthesized using the (Fe3+/Fe2+) coprecipitation. After 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-catalyzed oxidation of CNC, carbodiimide (EDC/NHS) was used for coupling amine-containing iron oxide nanoparticles that were achieved by dopamine li...

Background: Natural Organic Matters (NOMs) are pollutants that exist in many drinking water resources, cause problems treatment processes, and have adverse effects on human health. For this reason, these substances must be removed from via a proper method. Metal Frameworks (MOFs) novel adsorbents been widely considered recent years. In study, Uio-66 functionalized with NH2 was synthesized appli...

Mango industry processing disposes 40-60% of this fruit as residues, such peels and kernels. The exploration bioproducts from these industrial rejects can reduce environmental impact besides producing high value-added materials. In scenario, carboxymethyl starch nanoparticles were produced mango (Mangifera indica L.) kernel starch. These then decorated with thermoresponsive chains the amino ter...

We developed a method to use NH2-functionalized polymer films to align and immobilize DNA molecules on a Si substrate. The plasma-polymerized cyclohexane film was deposited on the Si substrate according to the radio frequency plasma-enhanced chemical vapor deposition method using a single molecular precursor, and it was then treated by the dielectric barrier discharge method in a nitrogen envir...

Synthesis and characterization of novel Tea Tree Oil (TTO) loaded antibacterial polyurethane rigid foams using two distinct methods is reported. In the first method, 3-aminopropyltriethoxysilane (APTS) functionalized mesoporous silica was used as carrier TTO for preparing amino-functionalized (TTO-NH2-MCM-41). second one, encapsulated by via sol-gel then APTS, nanocontainers with amino groups (...

Due to the unique optical properties like high brightness and narrow emission bands of Quantum dots, it is used as simple fluorescence materials in bio-imaging, immunoassays, microarrays, and other applications. To easy invistigate cell lines that overexpressed somtostatin receptors, somatostatin (SST) was conjugated with Quantum dots carrying PEG amine (Qdots-PEG-NH2). The conjugation of SST t...
