Poplar Science: Custom Proteins Drawn from Genetically Engineered Trees Expand Silicon Chips' Memory Capacity
The nano-poplar approach marks a new way to miniaturize memory elements while also increasing capacity, according to a university news release. The findings were published in the journal Nature Nanotechnology.
The technology involves genetically engineering poplar proteins so they can hybridize with the silica nanoparticles. The nanoparticles attach to the inner pore of the protein, and the poplar pores are arranged in an array of molecular memory elements.
The research team, led by Prof. Danny Porath at the Institute of Chemistry at Hebrew University, found the memory elements can carry out stable computing activity. They hope the technology can provide an alternative to current computer memory fabrication processes.
