The design was
specific to that of a biological synapse — a small gap that exists between adjoining neurons over which
chemical and electrical
signals are passed.
The goal here is to fashion simple biocomputers that use DNA and proteins to recognize
specific chemical targets, store a few bits of information, and then report their status by changing color or emitting some other easily detectable
signal.
These researchers are part of PNNL's Transformational Materials Science Initiative, which is investigating novel nanomaterials and technologies that generate electronic
signals in the presence of
specific chemicals or biological agents.
Airborne
chemicals, translated into neuronal
signals by
specific receptors in the nose, are sent directly to the olfactory bulb.
Registry parts include operators, which are segments of DNA to which repressor proteins bind to prevent gene transcription; cell - cell
signaling elements, which produce defined outputs in response to
specific chemical inputs; and riboregulators, which can be used to suppress the expression of particular genes by preventing translation of proteins they express.
By utilizing the tools of cell and molecular biology, he studies the mechanisms by which
chemical (for example,
specific cell adhesion molecules) or mechanical
signals (for example, cyclic strain) are sensed by cells and alter their proliferation and specialization to either promote tissue growth or destruction.
Pheromones are species -
specific naturally occurring
chemical signals that are excreted or secreted by an individual to trigger a social response in that same species.
