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

Magdassi, A Bassa, Y Vinetsky… - 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- ...

Amplification of complex gene libraries by emulsion PCR

R Williams, SG Peisajovich, OJ Miller, S Magdassi… - Nature …, 2006 -
The efficient amplification of genomic libraries, cDNA libraries and other complex mixtures of 
genes by PCR is impeded by two phenomena: firstly, short fragments tend to be amplified in 
preference to larger ones; and, secondly, artifactual fragments are generated by ...

[BOOK] Surface activity of proteins: chemical and physicochemical modifications

Magdassi - 2010 -
Offers discussions on the chemical and physicochemical modification of proteins for the 
enhancement of surface activity and functional properties in a variety of systems. The 
volume provides examples of specific applications of modified proteins in gelation, ...

Ink‐Jet Printing of Metallic Nanoparticles and Microemulsions

…, M Ben‐Moshe, S Aviezer, S Magdassi - 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. ...

[HTML] High-throughput screening of enzyme libraries: thiolactonases evolved by fluorescence-activated sorting of single cells in emulsion compartments

A Aharoni, G Amitai, K Bernath, S Magdassi… - Chemistry & biology, 2005 - Elsevier
Single bacterial cells, each expressing a different library variant, were compartmentalized in 
aqueous droplets of water-in-oil (w/o) emulsions, thus maintaining a linkage between a 
plasmid-borne gene, the encoded enzyme variant, and the fluorescent product this ...

In vitro compartmentalization by double emulsions: sorting and gene enrichment by fluorescence activated cell sorting

…, M Hai, E Mastrobattista, AD Griffiths, S Magdassi… - Analytical …, 2004 - Elsevier
Water-in-oil (w/o) emulsions can be used to compartmentalize and select large gene 
libraries for a predetermined function. The aqueous droplets of the w/o emulsion function as 
cell-like compartments in each of which a single gene is transcribed and translated to give ...

Directed evolution by in vitro compartmentalization

…, BT Kelly, E MastrobattistaV Taly, S Magdassi… - Nature …, 2006 -
The goal of in vitro compartmentalization (IVC) is to divide a large reaction between many 
microscopic compartments 1. This technique was first developed to generate'artificial cells' 
for the directed evolution of proteins (Fig. 1). Typically, an aqueous solution of genes and ...

Triggering the sintering of silver nanoparticles at room temperature

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 ...

Release of markers from the inner water phase of W/O/W emulsions stabilized by silicone based polymeric surfactants

Y Sela, S Magdassi, N Garti - Journal of controlled release, 1995 - Elsevier
Silicone based surfactants were used as stabilizers for W/O/W double emulsions with 
unusual mechanical stability. W/O/W multiple emulsions containing several markers were 
prepared. The entrapped markers were:(1) halide salts,(2) a typical drug, ephedrine ...

Role of a third liquid phase in phase-transfer catalysis

D Mason, S Magdassi, Y Sasson - The Journal of Organic …, 1991 - ACS Publications
The elimination of phenethyl bromide to styrene under phase-transfer catalytic conditions is 
shown to be sharply accelerated if a three-liquid-phase system can be engineered. 
Tetrabutylammonium bromide can promote such a system under certain conditions of ...
