Planarian Immobilization, Partial Irradiation, and Tissue Transplantation Otto C. Guedelhoefer IV1,2, Alejandro Sánchez Alvarado3,4 1Department of Neurobiology and Anatomy, University of Utah School of Medicine, 2Department of Molecular, Cellular and Developmental Biology, UCSB, 3Howard Hughes Medical Institute, 4Stowers Institute for Medical Research An effective method for grafting tissue of defined and consistent size between planaria is described. Also included is a description of how the immobilization technique used for transplantation can be adapted, in conjunction with lead shields, for the partial irradiation of live animals.
Planar and Three-Dimensional Printing of Conductive Inks Bok Yeop Ahn1, Steven B. Walker1, Scott C. Slimmer1, Analisa Russo1, Ashley Gupta1, Steve Kranz1, Eric B. Duoss1,2, Thomas F. Malkowski1,3, Jennifer A. Lewis1 1Department of Materials Science and Engineering, University of Illinois at Urbana-Champaign, 2Center for Micro- and Nanotechnology, Lawrence Livermore National Laboratory, 3Presently at the Interdisciplinary Center for Wide Band-gap Semiconductors, University Of California Santa Barbara Planar and three-dimensional printing of conductive metallic inks is described. Our approach provides new avenues for fabricating printed electronic, optoelectronic, and biomedical devices in unusual layouts at the microscale.
Fabrication of Electrochemical-DNA Biosensors for the Reagentless Detection of Nucleic Acids, Proteins and Small Molecules Aaron A. Rowe1, Ryan J. White1, Andrew J. Bonham1, Kevin W. Plaxco2 1Department of Chemistry and Biochemistry, University Of California Santa Barbara, 2Department of Chemistry and Biochemistry, Program in BioMolecular Science and Engineering, University Of California Santa Barbara "E-DNA" sensors, reagentless, electrochemical biosensors that perform well even when challenged directly in blood and other complex matrices, have been adapted to the detection of a wide range of nucleic acid, protein and small molecule analytes. Here we present a general procedure for the fabrication and use of such sensors.
