Biological Applications of "Smart Dust," or Porous Silicon Photonic Crystals


技术应用

In addition to those mentioned above, the researchers are currently exploring other biological applications, such as controlled drug-release, biomedical implants, artificial organs, and cell-based experimentation platforms.


详细技术说明

UC San Diego researchers have developed a new nanotechnology platform called "smart dust" with state-of-the art applications in almost every field of use, ranging from biological sensing and screening to communications technology. The invention utilizes micron-sized particles of silicon that have been etched and then chemically modified in such a way that each individual particle has its own addressable identity. This feature allows one to use thousands of particles together, each with its own tag, for high-sensitivity chemical or biological sensing, diagnostics, and low- and high-throughput screening of biomolecular compounds. The method does not require the use of fluorescent tags, but could be used in conjunction with them.

Title: Porous photonic crystal with light scattering domains and methods of synthesis and use thereof
Usefulness: Porous photonic crystal with light scattering domains and methods of synthesis and use thereof
Summary: For use in a cell-based biological and chemical sensor (claimed), for sensing presence, quantity and morphology of a target analyte, e.g. cell, macromolecule, protein, polymer, biomolecule, biopolymer and molecular complex, that is utilized in a genomic, proteomic, drug discovery, medical diagnostic, environmental sensing, pollution monitoring, detection of chemical or biological warfare agent and industrial process monitoring.
Novelty: Target analyte, e.g. cell, presence, quantity and morphology sensing method for use in cell-based biological and chemical sensor, involves exposing porous substrate to environment suspected of containing target analyte
