Grow Contaminant-Free Carbon Nano/Microstructures at Low-Temperature

  • Growth technique for creating carbon features of controllable dimensions
  • Uses a low-cost and readily accessible photocatalyst and laser to grow carbon nano- and microstructures at low temperature
  • Can produce custom patterns, including arrays of structures with pitch below 100 micrometers


The University of Central Florida invention describes methods of patterning well-defined nanoscale and microscale carbon structures with light using a defect-engineered photocatalyst. This invention avoids several shortcomings of current methods of carbon structure growth, such as external heating and residual contamination in the final products.

Stage of Development

Prototype available.


  • Uses a non-noble metal catalyst obtained by introducing defects in a fairly abundant material
  • Produces carbon features with no chemical or metallic contaminants and features can be tuned from a few nanometers to several millimeters in diameter and length
  • Takes seconds to grow structures
  • Growth process can be tuned at different wavelengths in the visible range, making it possible to design processes that take advantage of various lasers or solar illumination

Potential Applications

  • Interconnects for (nano)electronics
  • Microelectrodes for 3D sensor systems used in biotechnology
  • Electrodes for batteries and supercapacitors
  • Emitters for LED-type applications and emitters for sensing
  • Solar cells, sensors, devices such as diodes and transistors
