The Multidisciplinary Research Buildings is a state-of-the-art, three-story research facility completed and occupied in January 2006. Laboratory spaces on the outside of the building wrap around a shared core of research equipment and facilities, including bio-safety level 3 labs, a mass spectrometry lab and "clean" rooms.
Microfabrication Facilities, located on the first floor of the MRB, contains 2,400 ft2 of cleanroom space, 900 ft2 for a machining room, 400 ft2 of wet lab space and offices. This facility is under the direction of Drs. Susan Lunte and Karen Nordheden. The facility is available to KU researchers in all departments and provides training to new investigators and graduate students in the use of microfabrication procedures and equipment. In the long-term, the center will evolve into a self-supporting facility of service to the wider University of Kansas community.
The Microfabrication Facility cleanrooms consist of a gowning vestibule (200 ft2); a class 100 cleanroom for imaging (190 ft2); a class 100 area for photolithography (200 ft2); a class 1000 space for metal deposition (280 ft2); a class 1000 space for plasma etching (280 ft2); and a class 1000 wet lab for substrate etching, bonding, and device inspection (575 ft2). The facility has access corridors for gas tanks, house nitrogen, specialized hoods and lighting, and built in desiccators. The facility provides capabilities for photolithography, plasma etching of high surface ratio elements, glass etching, laser ablation, metal deposition, dielectric material deposition and microchip characterization. The major equipment in this facility is listed in the equipment section below.

- Herrick plasma cleaner
- Tencor Alpha Step 100 profilometer
- Lindberg blue tube furnace
- HF etching station
Evaluation of fabricated devices is performed with some of the following equipment:
- BAS potentiostats
- 0-30-kV power supplies
- 2-kV miniature power supplies (KU IDL)
- Dell computers, with epsilon EC detectors
- Jenway multi-output high voltage power supplies for microchips

The University of Kansas has an instrument design laboratory that can assist with the development of specialized potentiostats and data acquisition devices. The IDL designs and fabricates electronic and computer-based instrumentation as well as programmable mechanical devices that interact with the computer. It is fully equipped with test equipment and fabrication equipment, as well as significant stocks of integrated circuits, passive components, connectors, etc.
Tissue Culture Laboratory
This facility occupies ~2,000 sq. ft. of space in Malott Hall. The Tissue Culture component is a ~1,000 sq. ft. positive pressure lab totally designed for preparation and maintenance of cell cultures. The ante-room is designed for media preparation and is equipped with a large autoclave, water purification system, and several refrigerators and freezers, including a -80 degree C freezer. University lab staff members have access to all of the instrumentation, based on a sign-up system to reserve items for use as needed. The Facility is under the direction of an experienced tissue culture expert, who handles maintenance of the equipment and efficient utilization of the facility.
The Tissue Culture/Hybridoma Facility is equipped with 4 NuAire and Baker tissue culture hoods, 8 Forma and NuAire CO2 incubators, 1 double-chamber trigas incubator, a coulter counter, bioreactors, liquid N2 tanks for cell preservation, centrifuges, several microscopes, balances, and other small equipment items required for cell culture. Other components of the facility include Packard and Biotek UV/VIS, fluorescence, and chemiluminescence plate readers, a Becton Dickinson FACScan flow cytometer with two workstations, and a Nikon TE200 fluorescence microscope with video camera, imaging system, and computer.
