The Bioinspired Materials and Transduction Laboratory is housed in Dougherty Engineering Building at the University of Tennessee and includes 500sq. ft. of research space. This laboratory features a variety of measurement and data acquisition systems, optical characterization equipment, sample preparation equipment, fabrication tools, and chemical laboratory facilities necessary for the development and characterization of novel material systems.

Electrical Measurement and Data Acquisition:

  • Molecular Devices AxoPatch200B Patch Clamp Amplifier and Digidata 1440A  –  The AxoPatch200B is the top of the line patch clamp amplifier used throughout the electrophysiology community for performing low-noise, pA-level current measurements of live cells and synthetic lipid bilayers.   The Digidata 1440A is a 16-bit resolution, 16ADC/4DAC channel data acquisition system with sampling rates as high as 250kHz. The device connects to a computer via USB 2.0 and is operated using AxoScope 10 software.
  • National Instruments CompactDaq (CDAQ-9174) Modular Data Acquisition System – 4-slot chassis, USB interface to computer, Modules:  NI 9215 Analog Voltage input (16-bit, 4-channel, BNC, 100kHz), NI 9263 Analog Voltage output (16-bit, 4-channel, 100kHz), NI 9211 Analog Thermocouple (24-bit, 4-channel, 14Hz, built-in cold junction)
  • Tektronix TDS 1001B Digital Storage Oscilloscope – 2-channel, 40MHz, 500MS/s sampling rates, 2.5k record length, USB port for remote storage
  • Agilent 33210A Function/Arbitrary Waveform Generator – 10MHz function generator, 14-bit, 50 MSa/s, 8K-point arbitrary waveform generator, USB and GPIB interfaces
  • Fluke 87 V Multimeter

Micromanipulation and Microinjection:

  • World Precision Instruments SM325 Programmable Motorized Micromanipulator and Controller – 3-axis, stepper motor driven micromanipulator that features 25mm travel along each axis, with 0.1μm resolution.  The manipulator is controlled using the MCL3 controller, which allows for manual control via joystick or automated positioning with the accompanying software interface
  • Eppendorf Femtojet Microinjector – enables controlled injections of small liquid volumes of up to 100pL via independent control of injection pressure (0-6,000hPa in increments of 5hPa), compensation pressure (0-6,000hPa in increments of 5hPa), and injection time (0-99.9 seconds, in increments of 0.1 seconds).  The device features an integrated compressor and uses Eppendorf Femotips (0.5μm inner diameter at the tip).
