Hybrid biomaterials for nanobioelectronic device: toward biocomputing system
H
ybrid biomaterial for nanobioelecronic devices have emerged as a breakthrough with huge potentiality to generate new
concepts and technologies for the development of new age electronic devices. The main concept of bioelectronics was
generated from the fact that biomaterial, especially metalloproteins, can be used as a functional unit in an electronic device.
Major challenges in bioelectronic field include the miniaturization, and the demonstration of various functions implemented
in biomaterial to alter silicon-based electronic devices. It has been difficult to demonstrate a single molecular-based computing
device in current computing system, since such silicon-based system requires complex functionality to be developed at
the single molecular level. In this point of view, metalloprotein-based conceptual biomemory device was developed which
demonstrateed memory characteristics including ‘read’, ‘write’ and ‘erase’ function. Further, multi-bit memory function
and nanoscale memory function are also demonstrated. Afterwards new hybrid material including metalloprotein/DNA/
nanoparticle has been developed to construct bioprocessing device to achieve various functions at the single molecular
level. A metalloprotein that exhibits redox property is used as a biomemory signal source, and various nanoparticles with
complementary DNA and metal ions are used as input signals to acquire processed output signals. Various functions including
‘information reinforcement’, ‘information regulation’ and ‘information amplification’ are accomplished in this device due to
various input signals. The proposed hybrid material-based bioprocessing device by the integration with neural cell should be a
new type of platform for development of biomolecular-based biocomputing system.
