Human prostate specific antigen (PSA) standard solution and prostate specific antibody (Ab1 and Ab2) were purchased from Shenggong Bioengineering Ltd Company (Shanghai, China). Glutaraldehyde (25% aqueous solution), bovine serum albumin (BSA), (3-aminopropyl) triethoxysilane (APTES), Tri(2,2′-bipyridyl) dichlororuthenium (II) hexahydrate, and chitosan (CS) were obtained from Sigma-Aldrich Chem....

Organic-inorganic hybrid materials overcome drawbacks associated with alginate hydrogels. In this work, covalently coupled silica-alginate hybrids were prepared by Schiff base formation and sol-gel reaction using dialdehyde (ADA), (3-Aminopropyl) triethoxysilane (APTES), APTES/tetraethylorthosilicate (TEOS) precursors. The influence of the polysaccharide/inorganic ratio, nature inorganic precur...

Ultrasound micro-molding technology has proved useful in processing biodegradable polymers with minimum material loss. This makes this technology particularly suitable for the production of biomedical microdevices. The use of silica (SiO2) nanoparticles is also interesting because of advantages like low cost and enhancement of final properties. Evaluation of the capacity to create a homogeneous...

The development of negative electrode materials with better performance than those currently used in Li-ion technology has been a major focus recent battery research. Here, we report the synthesis and electrochemical evaluation situ-formed nitrogen-doped carbon/SiOC. were synthesized by sol–gel process using 3-(aminopropyl)triethoxysilane (APTES), sodium citrate glycerol. pyrolyzed was studied ...

The interaction of chemicals with DNA may lead to genotoxicity, mutation or carcinogenicity. A simple open tubular capillary electrochromatographic method is proposed to rapidly assess the interaction affinity of three environmental contaminants (1,4-phenylenediamine, pyridine and 2,4-diaminotoluene) to DNA by measuring their retention in the capillaries coated with DNA probes. DNA oligonucleot...

A novel mesoporous nanosphere functionalized with 3-(aminopropyl)triethoxysilane (APTES) and 2-(5-bromothiophen)imidazo[4,5-f][1,10]phenanthroline (5-Br-Tip) was synthesized (denoted as Tip-MSS). With the coordinating function of the 5-Br-Tip to lanthanide (Ln) ions, for the first time, LnL3(5-Br-Tip) complexes were linked to the mesoporous nanospheres. The derived materials, named Ln-Tip-MSS (...

Novel tertiary branched tetra-amines, quaternary branched penta-amines, linear penta-amines and linear hexa-amines were distributed as the major polyamines in six obligately extremely thermophilic eubacteria belonging to Thermoleophilum, Bacillus or Hydrogenobacter. The major polyamine of Thermoleophilum album and Thermoleophilum minutum was identified as a quaternary branched penta-amine, 4,4-...

Nanocomposites of aluminosilicate minerals, kaolins (kaolinite and halloysite) with natural different morphologies assembling with palladium (Pd) nanoparticles have been successfully synthesized through strong electrostatic adsorption and chemical bonding after surface modification with 3-aminopropyl triethoxysilane (APTES). Meanwhile, the influence of different morphologies supports on catalyt...
