SILVER NANOPARTICLE SURFACE ENABLED SELF-ASSEMBLY OF ORGANIC DYE MOLECULES

Fluorescence titration of methylene blue, rhodamine B and rhodamine 6G (R6G) by silver nanoparticle (AgNP) all resulted in an initial steep quenching curve followed with a sharp turn and a much flatter quenching curve. At the turn, there are about 200,000 dye molecules per a single AgNP, signifying self-assembly of approximately 36 layers of dye molecules on the surface of the AgNP to form a micelle-like structure. These fluorescence-quenching curves fit to a mathematical model with an exponential term due to molecular self-assembly on a AgNP surface, or “self-assembly shielding effect”, and a Stern-Volmer term (nanoparticle surface enhanced quenching). Such a “super-quenching” by AgNP can only be attributed to “pre-concentration” of the dye molecules on the nanoparticle surface that yields the formation of micelle-like self-assembly, resulting in great fluorescence quenching. Overall, the fluorescence quenching titration reveals three different types of interactions of dye molecules on AgNP surface: 1) self-assembly (methylene blue, rhodamine B and R6G), 2) absorption/tight interaction (tryptamine and fluorescein), and 3) loose interaction (eosin Y). We attribute the formation of micelle-like self-assembly of these three dye molecules on AgNP to their positive charge, possession of nitrogen atoms, and with relatively large and flat aromatic moieties.

The compounds herein have high Exhaustion Values (E), high Fixation Values (F) and high Efficiency Values (T) and show significant improvements in terms of reducing spent dyestuff in effluent, increasing dye affinity to the substrate, increasing the dye-substrate covalent bonding, increasing the ability to dye substrates at room temperature, decreasing the amount of dye that is removed during the post dyeing 'soaping off process' and therefore simplifying the post dyeing 'soaping off process' traditionally associated with dyeing cotton with fibre reactive dyes and reduction of staining of adjacent white fabrics. In addition, the compounds prepared above provide more intense dyeings and require less levels of salt for dyeing cotton substrates.

Reactive derivatives of sulforhodamine 101 with enhanced hydrolytic stability

The invention describes reactive dyes having an alkyl spacer attached via a sulfonamide bond to a sulforhodamine 101 fluorophore, and a variety of useful conjugates prepared therefrom. The increased length of the covalent linkage due to the alkyl spacer results in dye-conjugates having a number of surprisingly advantageous properties relative to previous sulforhodamine 101-labeled conjugates, including enhanced solubility and increased fluorescence. The reactive dyes of the present invention are more stable than the known compound sulforhodamine 101 sulfonyl chloride. Novel reactive dyes are described for selective modification of groups other than amines, including thiols and photoreactive derivatives.
