CHOICE POINTS--BREAST CANCER TREATMENT CD ROM

Not Available The proposed DDARPASBIR program would demonstrate the synthesis of retinal protein-based optoelectronic arrays using self-assembly techniques. The proposed method utilizes NanoSonic's patented and exclusively licensed molecular-level electrostatic self-assembly (ESA) approach to biomimetically grow multilayered active electronic devices. The selection of specific molecules and their processing into individual device monolayers by alternate ionic attraction and bonding allows the formation of adjacent photoactive, electrode and packaging layers. Prior NanoSonic research has demonstrated our ability to form ultrauniform many-layer films of proteins, noble metal and metal oxide nanoclusters, cage structured molecules and other materials by this process. The photoactive and electrode elements may be patterned in two-dimensions at the nanolevel, through control of the local isoelectric point during ESA processing. During the Phase I program, NanoSonic would demonstrate the incorporation of retinal and related photoactive molecules into uniform multilayered thin films by the ESA process, investigate the self-assemby of nanostructured electrodes leading to the formation of two-dimensional optoelectronic device arrays, study ways in which spectral sensitivity may be modified, and fabricate devices and evaluate their spectral and temporal responses. During Phase II, NanoSonic would work with several identified larger companies to transition the ESA processing of biologically-inspired optoelectronic devices to commercial manufacturing.
