Effect of size, shape, and surface modification on cytotoxicity of gold nanoparticles to human Hep-2 and canine MDCK cells [PDF]

open access: yes, 2012
There have been increasing interests in applying gold nanoparticles in biological research, drug delivery, and therapy. As the interaction of gold nanoparticles with cells relies on properties of nanoparticles, the cytotoxicity is complex and still under

Aptamer-based cocaine assay using a nanohybrid composed of ZnS/Ag2Se quantum dots, graphene oxide and gold nanoparticles as a fluorescent probe [PDF]

open access: yes, 2020
Authors report on a new fluoro-graphene-plasmonic nanohybrid aptamer-based fluorescent nanoprobe for cocaine. To construct the nanoprobe, newly synthesized glutathione-capped ZnS/Ag 2Se quantum dots (QDs) were first conjugated to graphene oxide (GO) to ...

What is the “modified” CTAB protocol? Characterizing modifications to the CTAB DNA extraction protocol

open access: yesApplications in Plant Sciences, 2023
AbstractCetyltrimethylammonium bromide (CTAB)–based methods are widely used to isolate DNA from plant tissues, but the unique chemical composition of secondary metabolites among plant species has necessitated optimization. Research articles often cite a “modified” CTAB protocol without explicitly stating how the protocol had been altered, creating non ...

Achiral dye/surfactant heteroaggregates for chiral sensing of phosphocholines [PDF]

open access: yes, 2015
An investigation, based on absorption and circular dichroism spectroscopy, was carried out on assemblies formed in water upon the interaction of heteroaggregates, composed of dyes (Congo Red or Evans Blue) and cetyltrimethylammonium bromide (CTAB), with ...

Voltammetric determination of the critical micellar concentration of surfactants by using a boron doped diamond anode [PDF]

open access: yes, 2010
The electrochemistry of three surfactants has been studied by voltammetry at boron doped diamond (BDD) electrode in sodium sulphate solutions. The electrochemical behaviour of these surfactants is characterized by an oxidation signal (peak or wave ...

Stability of Graphene Oxide encapsulated Gold Nanorods for optical sensing purposes [PDF]

open access: yes, 2018
This paper presents the synthesis and characterization of a graphene oxide encapsulated gold nanorod (GNR) complex, where its stability was investigated over time by recording the absorption spectra obtained using a UV/Visible spectrometer over the ...

How endo- is endo-?: surface sterilization of delicate samples: a Bryopsis (Bryopsidales, Chlorophyta) case study [PDF]

open access: yes, 2010
In the search for endosymbiotic bacteria, elimination of ectosymbionts is a key point of attention. Commonly, the surface of the host itself or the symbiotic structures are sterilized with aggressive substances such as chlorine or mercury derivatives ...

Smart worm-like micelles responsive to CO₂/N₂ and light dual stimuli [PDF]

open access: yes, 2017
CO₂/N₂ and light dual stimuli-reponsive worm-like micelles (WLMs) were obtained by addition of a relatively small amount of a switchable surfactant, 4-butyl-4´-(4-N,N-dimethylhexyloxy-amine) azobenzene bicarbonate (AZO-B6-CO₂), sensitive to the same ...
