Light-Absorbing and Emitting Dyes
Akita chemists have decades of experience making light-absorbing and emitting dyes, tailored to particular product requirements. Dyes are selected for absorption/emission of particular wavelengths in the UV, visible, or near-infrared regions of the spectrum, and designed to have the required thermo- and photostability, solubility, and brightness. We can incorporate dyes in suitable polymer hosts or conjugate them to proteins, antibodies, DNA, or other molecules, as well as providing the dyes in solid form or in a desired solution or suspension. Dyes can also be provided enclosed in or attached to micro- or nanoparticles. Common uses of dyes are for chemiluminescence, photoacoustic imaging, chemical sensing, laser line absorption, bioanalyte detection, detection of corrosion, cell staining, and other bioimaging. Fluorescent dyes can be made sensitive to a variety of analytes and conditions including ion concentration, pH, voltage, solvent polarity, and the presence of a wide variety of chemical species.

Akita designs and produces a wide variety of coatings including polymers, metals, and sol-gel (inorganic) coatings. Coatings are used to protect substrates from degradation, contamination, or corrosion, to incorporate chemical sensing features, to control permeation of water or oxygen, to impart color or hardness, or to increase or prevent wetting of the material by water or oils.

Akita coatings can be applied to a wide variety of substrates including flat substrates (glass, paper, plastics, metals), curved surfaces, and small particles. Coating methods we employ include spray, flow, dip, and brush coating, electroless metal deposition, vapor deposition, rod and blade coating, and monolayer coating of surfaces. Coating thicknesses can range from nanometers to millimeters depending on the materials and method employed. Coatings are cured (hardened) by a range of methods including chemical crosslinking, thermal curing at room temperature or elevated temperatures, and photo (light) curing.

Micro and Nanomaterials
Akita designs and produces a variety of micro and nanomaterials, including inorganic particles of metals and metal oxides, silica and polymer particles, and exotic materials such as iodates. We can modify the surface of these particles to control their solubility or polymer-encapsulate them to protect them from hydrolysis or oxidation.

We can characterize particulates by particle size, morphology, surface area, reactivity, or optical properties. Our expertise can take your product to new levels of performance that will set you apart from your competition. If you product uses particulates or could benefit by doing so, you need to be talking with Akita!
