A Photoactivable Microfluidic Device for Heavy Metal Ion Extraction Dissertation

• Jintana Nammoonnoy Dissertation from 2010. Shows previous spiropyran work in the Remcho lab

Photon-Controlled Phase Partitioning of Spiropyrans

• Rosario et al describe the creation of a spiropyran derivative. We are following their experimental methods to synthesize our spiropyrans.

Photon-Modulated Wettability Changes on Spiropyran-Coated Surfaces

• Rosario et al describe the creation of a photocapillary. They made use of a two step modification to separate each spiropyran with nonpolar tert-butyldiphenylsilyl groups.

Spiropyran-Modified Gold Nanoparticles: Reversible Size Control of Aggregates by UV and Visible Light Irradiations

• Shiraishi et al describe the fuctionalization of gold nanoparticles with a thiol terminated spiropyran dye. Seems like a simple method, however it takes 30min for large (~300nm) aggregates for form and then 90min for the aggregates to break up.

Spiropyran Polymeric Microcapillary Coatings for Photodetection of Solvent Polarity

• Florea et al describe solvent effects on spiropyran derivatives. The group developed a colormetric method for determining solvent polarity. The open form presents a blue shift in solvents on increasing polarity.

Synergy of Different Fluorescent Enhancement Effects on Spiropyran Appended onto Cellulose

• Weiguo Tian and Jintao Tian describe a method of creating spiropyran paper.

Dynamics of a photochromic spiropyran under aqueous conditions

• The dynamics of a water soluble spiropyran is investigated by means of femtosecond transient absorption spectroscopy in the visible and infrared spectral range revealing an ultrafast reversible switching behavior under aqueous conditions with a high fatigue resistance

Control of Nanopore Wetting by a Photochromic Spiropyran: A Light-Controlled Valve and Electrical Switch

• By modifying the surface of nanoporous alumina membranes using mixtures of a photochromic spiropyran and hydrophobic molecules, it is possible to control the admission of water into the membrane using light.

Lotus Effect Amplifies Light-Induced Contact Angle Switching

• A rough surface morphology is shown to significantly amplify the light-induced change in water contact angle of a photoresponsive surface.

Intramolecular Interactions in Photochromic Spiropyran-Merocyanine Polymers

• Methacrylate, acrylate, and styrene polymers with photochromic spiropyran side groups connected to the main chains through spacers of various lengths were prepared by free radical polymerization.

Plasma-Based Surface Modification of Polystyrene Microtiter Plates for Covalent Immobilization of Biomolecules

• We describe use of argon plasma to generate reactive hydroxyl moieties at the surface of polystyrene microtiter plates

Hydrophilized and Functionalized Microtiter Plates
