Nanomaterials are very cool. However, have you actually seen many of them come to market?<p>You know why? It&#x27;s extremely complex to manufacture them in any high-yield, high-throughput process. Since the mechanism relies on the properties of a nano-structure (however that is made via any number of techniques to record and make tiny 2D or 3D patterns, tubes, strings, etc), it is very difficult to make.<p>It&#x27;s very sensitive to vibrations, the kind you can&#x27;t feel and requires fancy highly-stabilized tables and vibration isolation systems that cost a lot to isolate a small area. You need a special room away from traffic, city noise etc if you want good, repeatable results.<p>I&#x27;ve yet to see this fundamental problem with production addressed. Would be curious to hear from someone working in the field.
