Cell Biophysics Laboratory

Cell Biophysics Lab
Principal Investigator: Aranda-Espinoza, Helim
Email: helim@umd.edu
Location: 3135 Jeong H. Kim Engineering Building

The Cell Biophysics Laboratory applies the theoretical and experimental machinery of physics and engineering to obtain a quantitative understanding of specific problems inspired by biological systems. The group studies the mechanics and motility of healthy cells, as well as those of cells with pathological conditions. Of particular interest for the group is to understand how the mechanical environment dictates cell functions.

Control of Miniaturized Systems for Mechatronic, Biological, and Clinical Applications Laboratory

Control of Miniaturized Systems for Mechatronic, Biological, and Clinical Applications Laboratory
Principal Investigator: Shapiro, Ben
Location: 3178 Glenn L. Martin Hall

Modeling, design, and control of micro- and nano-scale systems and flows for bio-chemical and clinical applications. The Shapiro Group chooses applications where control can dramatically improve or allow new capabilities, and focuses on areas that will allow better diagnosis and treatment of people. Current projects range from precision and gentle control of individual cells on chip, e.g. for cell handling, sorting, and complex sample preparation, to control of magnetic nano-particles in people, for drug delivery to the inner ear and to primary and metastatic tumors. (Above: Feedback control of magnetic fields to focus chemotherapy coated nano-particles to deep tissue tumors.)

Laboratory for MicroTechnologies

Laboratory for MicroTechnologies
Principal Investigator: Smela, Elisabeth
Email: smela@umd.edu
Location: 2176 Martin Hall

The Laboratory for MicroTechnologies focuses on developing new technologies at the micro-scale that combine conventional inorganic materials and devices with organic, polymeric, and biological materials or living cells. Group members work in the area of cell-based sensing, in close collaboration with Professor Abshire, in which cells are cultured onto CMOS/MEMS devices and monitored using a range of sensing modalities. One application is an olfactory sensory neuron based bionose-on-a-chip. Associated technologies include microfluidics and dielectrophoresis (DEP). The group also has extensive experience with polymeric "artificial muscles," including microfabricated conjugated polymer actuators, dielectric elastomer actuators, and a new type of hydraulic "nastic" actuator. In addition, lab members are developing compliant electrodes for use with these actuators and flexible electronics. The lab features equipment for driving and characterizing actuators, for characterizing thin films, and for handling cells.

MEMS Sensors and Actuators Laboratory (MSAL)

MSAL
Principal Investigator: Ghodssi, Reza
Location: 2201 J. M. Patterson Building

The MEMS Sensors and Actuators Laboratory (MSAL) focuses on the design, fabrication, and testing of self-sustaining adaptive integrated bio-microsystems for chemical and biological sensing. The devices are designed using a variety of both in-house and commercial simulation software packages and developed utilizing state-of-the-art micro and nano fabrication and characterization techniques. Current projects include microfluidic-based opto-mechanical platforms for monitoring bacterial quorum sensing, next generation battery and fuel cell devices using the tobacco mosaic virus (TMV), and integrated III-V optical microsystems for chemical vapor sensing.

Sang Bok Lee Research Group

Electrodeposition
Principal Investigator: Lee, Sang Bok
Email: slee@umd.edu
Location: 2112, 3113 and 3115 Chemistry Building

Professor Lee's expertise in nanomaterials synthesis and electrochemistry forms the foundation of his research program. The Lee Group is, in general, interested in the synthesis of 1-D nanotubular and nanowire structures with various materials, since the 1-D structure has many attributes that other nanostructures do not have. The group is also interested in application of these various 1-D naostructures in the biomedical, materials, and energy fields. Current research projects may be categorized into three major areas: (1) synthesis and characterization of nanotube structures with various electronic and/or electrochemical materials and their application to ultrafast electrochromic display and high-power energy storage devices, (2) synthesis and characterization of bio-nanotubes for biomedical applications such as targeted drug delivery and biosensors, and (3) investigation of fundamental physical and chemical properties of nanostructured  materials such as diffusion and reaction problems in a confined geometry of silica nanotube.

Wang Group
