This site has had a few recent discussions about the overlaps between nanotech and cleantech (
here, and
here, among others), but as always there are a few follow-up items that might be of interest to cleantech investors:
- Charles Choi's most recent Nano World column listed what he describes as the "Ten most overlooked nano firms" -- mostly firms that have chosen to bootstrap or are family-owned instead of getting VC backing. But while the list of companies is by itself interesting, it also serves as a nice survey of the wide variety of applications -- some, but not all, cleantech -- being targeted by nanotech startups.
- Whether those firms are being overlooked or not, VC investments in nanotech are starting to come back. In the first quarter of this year, 12 nanotech firms raised $155M, about as much as had been raised by nanotech firms in the three previous quarters combined. There were a few big deals in there that temporarily drove a particular spike in the numbers, but it still appears to be a positive trend.
