I've just returned from the World Money Show in Orlando where more than 10,000 investors gathered to learn about global investing. I had a chance to meet with many of the U.S. and foreign financial experts featured at the show, and over the next week I will share some of their top investment ideas. To view all of the stocks featured in this special global report, click here.

As an advisor, scientist, and venture capitalist, Josh Wolfe is a recognized leader in nanotechnology; in fact, he was among a handful of industry experts invited to join President Bush in the Oval Office when he signed the landmark nanotech funding bill.

The ideas that he recommends are often meant for the more-sophisticated investor, as can be seen from his latest global nanotech idea -- Oxonica (LSE:OXN), a London-listed nanotech firm. Intriguingly, he speculates that the company may soon list its shares in the U.S.

The editor of The Forbes/Wolfe Nanotech Report explains, "Oxonica, which supplies nanomaterials for the energy, security, health care, and materials sectors, appears to be bucking the trend. Spun out of Oxford University in 1999, Oxonica has already established itself as a leading nanotech start-up.

"Recently, it was rated as a top start-up for corporate partnership by nanotech strategic advisory firm Lux Research." For full disclosure, he notes that his venture firm Lux Capital is an equity investor in Lux Research.

Meanwhile, he notes, "The key to Oxonica's success has been its portfolio management approach to commercializing nanomaterials. Oxonica has products in its pipeline for industries as diverse as cosmetics, energy, security, and bio-diagnostics and it has not restricted itself to being a one-trick pony.
