Piece description from the artist
This is a pretty straightforward drawing of the principles in size exclusion separations and chromatography. Little porous beads are packed together, and a solution of molecules passes through the packed bed of beads. The large molecules are too big for the pores of the beads and they quickly pass straight through the packed bed. Smaller molecules can explore more of the bead porosity and take a longer path – and longer time – through the bed. The underlying mechanism is different than, for example, paper chromatography, which you can try at home.
Dr. Regina Valluzzi has an extensive scientific background in nanotechnology and biophysics. She has been a scientist in the chemical industry, a green chemistry researcher, a research professor at the engineering school at Tufts, a start-up founder engaged in technology commercialization, and a start-up and commercialization consultant.
Even during periods of intense activity as a scientist, Dr. Valluzzi has always held a strong interest in the visual arts and in visual information. While she majored in Materials Science at MIT, she also obtained a second degree in music and a minor in visual studies. Visual arts have managed to permeate her technical work; during her Ph.D in Polymer Science and Engineering at UMass Amherst, she completed a thesis that required advanced electron microscopy, image analysis, and theoretical data modeling. These experiences provided the visual insight and information that now influences much of her artwork.
Dr. Valluzzi’s work has been included in private collections across the US, UK, Germany, Canada, Japan, Netherlands, Switzerland, Bulgaria, Dubai and Malta, and in the corporate collection of "Seyfarth Shaw" Boston law offices around Boston. She has a selection of pieces on loan to the MIT Materials Science and Engineering Department as indoor public art. Her accomplishments include having published thirty articles in peer-reviewed scientific journals, having made several scientific patents, having been a subject matter expert for an encyclopedia chapter, and having been invited to speak at science talks across the US, Europe, and Japan.
