Sol-gel-based silver nanoparticles-doped silica – Polydiphenylamine nanocomposite for micro-solid-phase extraction.

Anal. Chim. Acta 886 , 56-65, (2015)

A nanocomposite of silica-polydiphenylamine doped with silver nanoparticles (Ag-SiO2-PDPA) was successfully synthesized by the sol-gel process. For its preparation, PDPA was mixed with butanethiol capped Ag nanoparticles (NPs) and added to the silica sol solu...

Resorcinol-formaldehyde xerogel as a micro-solid-phase extraction sorbent for the determination of herbicides in aquatic environmental samples.

J. Sep. Sci. 38 , 2305-11, (2015)

In this study, organic aerogels were synthesized by the sol-gel polycondensation of mixed cresol with formaldehyde in a slightly basic aqueous solution. Carbon aerogels and xerogels are generated by pyrolysis of organic aerogels. The novel sol-gel-based micro...

A novel amperometric biosensor based on gold nanoparticles anchored on reduced graphene oxide for sensitive detection of l-lactate tumor biomarker.

Biosens. Bioelectron. 69 , 280-6, (2015)

In this work, a novel amperometric biosensor based on gold nanoparticles anchored on reduced graphene oxide (RGO-AuNPs) and l-lactate dehydrogenase (LDH) was developed for the sensing of l-lactate. Firstly, the RGO-AuNPs modified screen printed electrodes wer...

The sol-gel prepared SiO2-CaO-P2O5 composites doped with Metronidazole for application in local delivery systems.

Pharm. Dev. Technol. 17(6) , 697-704, (2012)

The aim of this study was to evaluate the physical properties, chemical structure and bioactivity of sol-gel processed oxide (SiO(2)-CaO-P(2)O(5)) composites used as controlled release materials for Metronidazole-drug applied in periodontal disease treatment....

Preparation and evaluation of open tubular C18-silica monolithic microcartridges for preconcentration of peptides by on-line solid phase extraction capillary electrophoresis.

Anal. Chim. Acta 846 , 51-9, (2014)

In this study, C18-silica monoliths were synthesized as a porous layer in open tubular capillary columns, to be cut later into microcartridges for the analysis of neuropeptides by on-line solid-phase extraction capillary electrophoresis with UV and MS detecti...

Versatile ene-thiol photoclick reaction for preparation of multimodal monolithic silica capillary columns.

J. Chromatogr. A. 1365 , 140-7, (2014)

This paper presents a photografting process of monolithic silica capillary columns based on the ene-thiol click chemistry. This study is performed on a generic vinyl-functionalized silica monolith (Hmin 61m). The photoclick reaction is investigated using diff...

Single-step approach for fabrication of vancomycin-bonded silica monolith as chiral stationary phase.

J. Chromatogr. A. 1358 , 208-16, (2014)

A vancomycin-bonded silica monolithic column for capillary electrochromatography (CEC) was prepared by a single-step in situ sol-gel approach. This sol-gel process incorporates a synthetic sol-gel precursor which contains a macrocyclic antibiotic, vancomycin,...

Core-shell silver nanoparticles for optical labeling of cells.

Anal. Biochem. 458 , 43-8, (2014)

Silver nanoparticles have been modified with self-assembled monolayers of hydroxyl-terminated long chain thiols and encapsulated with a silica shell. The resulting core-shell nanoparticles were used as optical labels for cell analysis using flow cytometry and...

Chiral SiO2 and Ag@SiO2 Materials Templated by Complexes Consisting of Comblike Polyethyleneimine and Tartaric Acid.
