The theme of our NIH Nanomedicine Development Center is design of biomimetic nanoconductors and devices utilizing nanoconductors. The model theoretical systems are native and mutant biological channels and other ion transport proteins and synthetic channels, and heterogenous membranes containing channels and transporters. The model experimental systems are engineered protein channels and synthe...
As a novel biomimetic polymer, we have developed polymer gels with an autonomous self-oscillating function. This was achieved by utilizing oscillating chemical reactions, called the Belousov-Zhabotinsky (BZ) reaction, which is recognized as a chemical model for understanding several autonomous phenomena in biological systems. Under the coexistence of the reactants, the polymer gel undergoes spo...
Although peptide amphiphiles have been explored as nanomaterials for different applications, nanostructures formed by hierarchical molecular assembly of sequencespecific peptidomimetics are much less developed. Such protein-like nanomaterials could enhance the current application of peptide-based amphiphiles by enriching the diversity of nanostructures, increasing in vivo stability for biomedic...
We studied the application of Biomimetic Pattern Recognition to speaker recognition. A speaker recognition neural network using network matching degree as criterion is proposed. It has been used in the system of textdependent speaker recognition. Experimental results show that good effect could be obtained even with lesser samples. Furthermore, the misrecognition caused by untrained speakers oc...
In the past decade, a large number of robots have been built that explicitly implement biological navigation behaviours. We review these biomimetic approaches using a framework that allows for a common description of biological and technical navigation behaviour. The review shows that biomimetic systems make signi cant contributions to two elds of research: First, they provide a real world test...
With the advent of human assisted reproduction in the year 1978 numerous techniques were developed to isolate spermatozoa capable to fertilize oocytes. While early methodologies only focused on the aim of isolating viable, motile spermatozoa, with further progress of assisted reproductive technology, particularly for ICSI, it rapidly became clear that these two parameters are insufficient for t...
