NanoSpire’s business and technology focus is the harnessing of high speed liquid cavitation reentrant microjets. NanoSpire’s technology is based on cavitation, a boiling phenomenon that involves a change of phase from the liquid to the gaseous state of a particular substance. A laser, ultrasound or other energy source is used to create small high-energy vapor bubbles through phase transition. The collapse of cavitation bubbles in close proximity to a wall generates supersonic liquid microjets naturally pointed towards a wall or other restriction to the collapse of the bubble.

NanoSpire’s patented methods build on, but go beyond the energetic process seen in nature. The size, strength and direction of cavitation reentrant microjets can be controlled by our patented methods to a very high degree of accuracy. Cavitation microjets can travel at up to Mach 4 and are capable of drilling a hole as small as a few nanometers in a diamond. Multiple controlled bubbles are also possible allowing lines to be machined as well as other form factors and machining applications. Cavitation allows a high aspect ratio machining to be obtained and is very repeatable. The technology can mill materials ranging from as soft as plastic to as hard as diamond. The technology can reach across numerous markets including many applications in the membrane/sensor area, (healthcare, automotive, aerospace, etc.), fuel cells, semiconductors, MEMS/NEMS, biotech, microfluidics, instruments and microsurgery markets, among others.
