Workplace social networking company Mzinga has raised a hefty $32.5 million, and used some of that money to purchase a similar company called Prospero Technologies. Until now, Mzinga has focused on in-company social networks, but the acquisition should allow it to create similar offerings on the customer side, which is Prospero’s specialty.

The big gain for Mzinga appears to be Prospero’s social media technology, which allows companies to interact with their customers through social networking, advertising, message boards, chats, reviews and blogs. Mzinga touts the social media platform’s versatility — it can be customized and integrated into your website through widgets, templates and API.

With the merger, Burlington, Mass.-based Mzinga has become a an even more formidable player in this field — it now has 150 employees and $30 million in annual revenue. It’s possible other enterprise software companies will consider consolidating to keep up.

Neither Mzinga nor Prospero was doing anything revolutionary (Mzinga offers a standard suite of blogs, wikis, idea-sharing applications and discussion forums), but both companies have attracted impressive customer bases. Most notably, Prospero’s clients before the merger included AOL, Disney, ESPN and the Washington Post.

The funding was led by W Capital Partners, which was joined by Bluecrest Capital Finance, GE Capital and Knowledge Industries.

Lab-tools maker Advion BioSystems acquires NanoTek — Advion BioSystems, an Ithaca, N.Y., developer of “lab-on-a-chip” microfluidics systems, acquired Knoxville, Tenn.-based NanoTek.

Microscopy company Ionscope raises $1.4M — Ionscope, a London-based developer of new scanning ion conductance microscopy technology, raised $1.4 million (£680,000) from individual investors of the Cambridge Angels Group.

Encore Path raises $500K for stroke rehabilitation — Encore Path, a Baltimore developer of training devices to assist in the rehabilitation of stroke patients, raised $500,000 in seed funding, VentureWire reports. Investors included the Maryland Venture Fund of the state’s Department of Business and Economic Development and the Maryland Technology Development Corp., as well as angel investors and friends and family. The company was originally founded in 2006 as NewRegen with a focus on neural rehabilitation for stroke patients. Now Encore Path is developing a training device for restoring arm movement, and hopes to raise a larger first round next year when that device launches.

Olive Software appears to have survived a tough rejection by Google last year.

The Santa Clara, Calif. company helps transfer off-line content into a format which Google can search. It converts PDF documents, microfilm and any other files to XML. Google courted the company aggressively, and did so much analysis of the company’s technology that some at the company felt violated when Google abandoned it at the altar.

However, Olive has just gotten new funding, $5 million in debt from BlueCrest Capital Finance of London, VentureWire reports (sub required).
