  • news: 15th annual materials and optics poster competition (MRS/Optica) / april 28, 2022 - clemson, sc

    The MRS/Optica (formally OSA) Materials and Optics Poster Competition was held for the fifteenth year on April 28, 2022 at the state-of-the-art Watt Family Innovation Center housed on Clemson University's main campus. This competition serves as the primary showcase of materials and optics research being performed at Clemson University and surrounding universities. Each year sees more posters, visitors, and judges. This year, 30 poster presenters from Clemson University, and Furman University presented their optical-based materials research.

    The competition was supported by the Center for Optical Materials Science and Engineering Technologies (COMSET), the Clemson University Department of Materials Science and Engineering, Tetramer Technologies, Milliken, and Poly-Med. Winners of the competition were graduate students, Tobias Jutten (Clemson University, Department Chemistry, University of Glassgow), William Sands (Clemson University, Department of Materials Science and Engineering), and Lauren Slann (Clemson University, Department of Automotive Engineering, Department of Materials Science and Engineering), and undergraduate students, Megan Williams (Clemson University, Department of Materials Science and Engineering) and Emily Dowker (Furman University).
    Dr. Keisha Walters from the University of Arkansas provided the keynote talk on stimuli responsive polymer systems to kick-off the competition. The night also functioned as a prime networking opportunity for students as over 15 members of industry were present at the competition in addition to 20 academic faculty members from Clemson University and surrounding universities.

    Haley Jones was the president of the Clemson Graduate Student Chapter of Optica and Ben Grant was the president of MRS. Eric Zhang, Sarah Mell, and Travis Wanless presented at this poster competition. The title of their posters were.....

  • news: sequential intraparticle Förster resonance energy transfer for multi-wavelength bioimaging

    The Foulger group published an article in Optical Materials Express that presented a general strategy for creating core/shell nanoparticles composed of a silica core over which a propargyl methacrylate (PMA) shell was polymerized around. To employ the shell coating, the surface of the silica nanoparticles (SiNPs) was modified with an alkene-terminated organometallic silane linker that allowed for the covalent attachment of a poly(propargyl methacrylate) (pPMA) shell. The alkyne groups resulting from the pPMA shell were utilized in copper(I)-catalyzed azide/alkyne cycloaddition (CuAAC) reactions to attach azide-modified Förster resonance energy transfer (FRET) pairs of naphthalimide (azNap), rhodamine B (azRhod), and silicon phthalocya- nine (azSiPc) derivatives to the shell surface. The luminescence of the system was manipulated by the covalent attachment of one, two, or three of the fluorophores resulting in no energy transfer, one energy transfer, or two energy transfers, respectively. When all three fluorophores were attached to the core/shell particles, an excitation of azNap with a wavelength of 400 nm resulted in the sequential energy transfer between two FRET pairs and the sole emission of azSiPc at 670 nm. These particles may have applications as bioimaging probes as their luminescence is easily detected using fluorescence microscopy.

  • news: using polymers to mimic biological synapses

    The Foulger group has been active in developing non-conjugated polymers for use as synaptic mimics and recently published an article in Advanced Electronic Materials on a carbazole derivatized n‐alkyl methacrylate polymeric memristor which acts as a flexible synaptic substitute. A biological synapse is a junction between two nerve cells and consists of a tiny gap across which electrical impulses pass by diffusion of a neurotransmitter and are the basis for cognitive responses in living creatures. The group's aim is to develop polymeric equivalents that can be printed in "physical" neural networks.

  • news: prof. foulger highlighted in clemson world

    Clemson World recently presented an article on Prof. Foulger's research effort in non-invasive optogenetics. Foulger (the primary investigator) and two collaborators, neuroscientists Lori McMahon at the University of Alabama at Birmingham and Jason Weick at the University of New Mexico, recently won $6 million grant from the National Science Foundation to develop X-ray-triggered radioluminescent particles to control brain functions. Foulger, as the materials scientist and director of Clemson’s Center for Optical Materials Science and Engineering, is responsible for creating the scintillating nanoparticles.

  • news: ways to enhance cancer cell death through apoptosis

    The Foulger group published an article in Biomaterials Science that presented a general strategy for enhancing apoptosis in cancer cells by reducing "survivin", a member of the family of inhibitor of apoptosis proteins (IAP). To do this, sub-100 nm poly(propargyl acrylate) (PA) particles were surface modified through the copper-catalyzed azide/alkyne cycloaddition of an azide-terminated survivin ligand derivative (azTM) originally proposed by Abbott Laboratories and speculated to bind directly to survivin (protein) at its dimer interface. Using affinity pull-down studies, it was determined that the PA/azTM nanoparticles selectively bind survivin and the particles can enhance apoptotic cell death in glioblastoma cell lines and other survivin over-expressing cell lines, such as A549 and MCF7, relative to cells incubated with the original Abbott-derived small molecule inhibitor.
