Molecular engineering of innovative systems that mimic the biological (i.e., biomimetic systems) in efforts to solve technological problems.
Future advances in many areas of interest to chemical engineers including catalysis, advanced materials, and separations will require engineering at the molecular scale. Since the direct manipulation of individual molecules presents obvious technological difficulties, much research has focused on self-assembling systems. The living cell is the ultimate self-assembled system with unrivaled capabilities in separations, sensing and synthesis; and lipid bilayer membranes are critical self-assembled structures for cell functioning as they serve, for example, to define cell boundaries, to compartmentalize reactions in controlled environments, and to provide scaffolding for the molecular machines involved in signal and energy transduction. My research projects on vesicular biomimetic membranes for separations, metal ion detection and nanoparticle synthesis; and on lipid-modified electrodes for biosensor development and for electroenzymatic chiral synthesis were conceived with the attributes of cell membranes in mind. Another common theme in my research, therefore, is the reliance on self-assembly to produce new technology that is critically dependent on molecular-scale structure.

Technical Research Interest:
The Monbouquette group conducts research on biosensors,
the biotechnological applications of extremely thermophilic
microorganisms, protein nanocapsule technology, and on
the molecular engineering of surfaces. The group is collaborating
with a UCLA neuroscientist on the micromachining of
biosensors for in vivo monitoring of neurotransmitter release
and uptake. In other work, a reporter enzyme has been engineered
to behave as a molecular switch for several sensing
applications under exploration including the detection of environmental
toxins and the high-throughput screening of drug
candidates. Extremely thermophilic microbes are being investigated
as a source of enzymes and metabolic pathways useful
in specialty chemical synthesis and of highly stable lipids for
potential applications in drug delivery and in biosensor design.
The Monbouquette laboratory also is discovering conditions
for the controlled opening and closing of naturally occurring
protein nanocapsules, in collaboration with Prof. Rome's group, such that they may be useful in drug delivery or in
the synthesis of nanomaterials. Finally, the group is pursuing
development of a process for the creation of complex, userdefined
surface patterns with ~2-3 nm feature size. This new
nanopatterning concept is based on the use of electrophoretically
mobile, photocatalytic nanoparticles as "pens" to
draw nanopatterns on a photocatalytically reactive surface.
