Solubility Enhancement of Hydrophobic Drugs

Micelle formation addresses low solubility in IV drug delivery, overcoming clinical limitations.

Fluorescence Lifetime Measurement

Fluorescence lifetime measurement is advantageous over intensity-based measurements. Applications include fluorescence lifetime assays, sensing and FLI.

Ruthenium-based dyes for Dye-sensitized Solar Cells

Dye-sensitized solar cells (DSCs) are 3rd generation solar cells combining the promise of high efficiency with low production costs.

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm
