Silver nanoparticles as pigments for water-based ink-jet inks

…, A Bassa, Y Vinetsky, A Kamyshny - Chemistry of …, 2003 - ACS Publications
Stable concentrated aqueous dispersions of silver nanoparticles, which can be employed as 
pigments in water-based ink-jet inks, are obtained by using sodium carboxymethyl cellulose 
as a stabilizer. Low-viscosity ink-jet inks were prepared and printed by a commercial drop- ...

Ink‐Jet Printing of Metallic Nanoparticles and Microemulsions

Kamyshny, M Ben‐Moshe, S Aviezer… - Macromolecular …, 2005 - Wiley Online Library
Summary: Two types of ink-jet inks are presented: ink containing an aqueous dispersion of 
silver nanoparticles and an oil-in-water microemulsion-based ink. The metallic ink contains 
nanoparticles of silver, which are formed in the presence of an ionic polymeric stabilizer. ...

Triggering the sintering of silver nanoparticles at room temperature

S Magdassi, M Grouchko, O Berezin, A Kamyshny - ACS nano, 2010 - ACS Publications
A new approach to achieve coalescence and sintering of metallic nanoparticles at room 
temperature is presented. It was discovered that silver nanoparticles behave as soft particles 
when they come into contact with oppositely charged polyelectrolytes and undergo a ...

Formation of air-stable copper–silver core–shell nanoparticles for inkjet printing

M Grouchko, A Kamyshny, S Magdassi - Journal of Materials Chemistry, 2009 -
Copper nanoparticles can be utilized as a low-cost replacement for silver and gold 
nanoparticles which are currently used in inkjet printing of conductive patterns. However, the 
main obstacle for using copper nanoparticles is their spontaneous oxidation at ambient ...

Polymer–surfactant interactions: Binding mechanism of sodium dodecyl sulfate to poly (diallyldimethylammonium chloride)

G Nizri, S Lagerge, A Kamyshny, DT Major… - Journal of colloid and …, 2008 - Elsevier
The binding mechanism of poly (diallyldimethylammonium chloride), PDAC, and sodium 
dodecyl sulfate, SDS, has been comprehensively studied by combining binding isotherms 
data with microcalorimetry, zeta potential, and conductivity measurements, as well as ab ...

Hydrophobically modified human IgG: surface and biological activities

Kamyshny, S Magdassi - Colloids and Surfaces B: Biointerfaces, 1997 - Elsevier
Hydrophobic modification of human IgG by fatty acid esters (C8, C12 and C16) of N-
hydroxysuccinimide was carried out. Such a modification leads to a spontaneous formation 
of micelle-like colloidal clusters with a mean diameter of 19.9–22.7 nm for C8-modified ...

Ring stain effect at room temperature in silver nanoparticles yields high electrical conductivity

S Magdassi, M Grouchko, D Toker, A Kamyshny… - Langmuir, 2005 - ACS Publications
We demonstrate that metallic rings formed spontaneously at room temperature via 
evaporation of aqueous drops containing silver nanoparticles (20-30 nm in diameter) exhibit 
high electrical conductivity (up to 15% of that for bulk silver). The mechanism underlying ...

Copper nanoparticles for printed electronics: routes towards achieving oxidation stability

S Magdassi, M Grouchko, A Kamyshny - Materials, 2010 -
Abstract: In the past few years, the synthesis of Cu nanoparticles has attracted much 
attention because of its huge potential for replacing expensive nano silver inks utilized in 
conductive printing. A major problem in utilizing these copper nanoparticles is their ...

Adsorption of hydrophobized IgG and gelatin onto phosphatidyl choline-coated silica

Kamyshny, O Toledano, S Magdassi - Colloids and Surfaces B: …, 1999 - Elsevier
Covalent modification of human IgG and gelatin (type A) by fatty acid esters (C8, C12 and 
C16) of N-hydroxysuccinimide was carried out. Preparations of hydrophobized IgG 
containing 9 and 25 attached caprylic and 25 palmitic chains and preparations of gelatin ...

Adsorption of native and hydrophobized human IgG onto silica: isotherms, calorimetry, and biological activity

Kamyshny, S Lagerge, S Partyka, P Relkin… - Langmuir, 2001 - ACS Publications
Adsorption onto silica of native human IgG and its hydrophobized forms prepared by 
covalent attachment of 11, 25, and 52 C8 alkyl chains was studied. All hydrophobized IgGs 
spontaneously form micellelike aggregates (nanoclusters) in aqueous solutions with a ...
