All about Functional Dyes
Functional dyes are a type of dye that not only gives materials color, but also has special functional properties. They respond to external stimuli (such as light, heat, electricity, pressure, etc.) and exhibit properties beyond traditional dyeing uses, such as luminescence, energy conversion, bio-marking or chemical sensing.

What is Functional Dye?
Functional dyes possess additional application properties beyond their conventional coloration capabilities. Many special functions found in functional dyes relate directly to advanced technology sectors including light dynamics, electrical properties, thermal characteristics, chemical behavior, and biochemical interactions. Photochromic dyes shift colors when exposed to light which brings aesthetic value to textiles while fluorescent dyes absorb visible light and emit fluorescence to boost visual effects.
What are the Features of Magnetic Beads?
Photoresponsiveness
Most functional dyes absorb or emit light in the visible or near-infrared (NIR) spectral range. For example, the application of BODIPY dyes in the NIR region can enhance the penetration depth of biological imaging.
Multifunctionality
The performance of functional dyes can be regulated by molecular design, such as adjusting the fluorescence wavelength and room temperature phosphorescence efficiency through assembly-induced emission strategies, expanding the new functions of traditional dyes.
Biocompatibility
Some functional dyes are suitable for life sciences, such as fluorescent probes for cell labeling, gene sequencing or early cancer screening.

Functional dyes for dye-sensitized solar cells
El-Shishtawy, Reda M. International Journal of Photoenergy 2009.1 (2009): 434897.High-tech applications based on optoelectronics, such as dye-sensitized solar cells, photochromic materials, liquid crystal displays and newer emissive displays, biomedical applications such as fluorescent sensors and anticancer treatments such as photodynamic therapy, require new dyes that meet new and demanding standards. Dyes designed for these high-tech applications and related UV- and especially IR-active molecules are generally referred to as functional dyes.
New solar cell manufacturing methods can be used to scale up and reduce costs. For this purpose, a new generation of solar cells, called dye-sensitized solar cells (DSCs), has been reported. Dye-sensitized solar cells usually consist of a dye-adsorbed nanoporous TiO2 film prepared on a transparent conducting oxide. The film is immersed in an electrolyte containing a redox couple and placed on a platinum counter electrode. After absorbing a photon, the excited electrons within the sensitizer molecules are transferred to the conduction band of the TiO2 and diffuse through the porous TiO2 network to the contacts.
