Aqdot wins CUE £1k Challenge

The second stage of Cambridge University Entrepreneurs‘ Business Creation Challenge has awarded 11 prizes of £1000 last night at the Department of Chemistry, University of Cambridge. Aqdot is proud to announce that it has been awarded a prize in the technology stream.

The founder and CEO of Pavegen, Laurence Kemball-Cook, awarded the prize certificate to Aqdot, after a series of elevator pitches from the competition entrants to a crowd of students, investors, and local business community.

Aqdot wins CUE’s £100 for 100 Words Challenge

The first stage of the Cambridge University Entrepreneurs (CUE) £100 for 100 Words Challenge has ended and CUE was awarded £100 for its 100-word summary of the business idea.

Headed by Dr Roger Coulston, this is the Aqdot team’s first of the many awards to come.

“Microencapsulation is currently a multi-billion ($USD) a year industry with established applications in food, cosmetics, drug delivery, diagnostics, and electronic displays. The current unmet consumer demand is to produce inexpensive capsules that allow for the triggered release of a cargo. This is a critical industry challenge over the next decades. Aqdot has developed an economically viable method to produce capsules with the unprecedented ability to actively and passively release fragrances, enzymes, cells, and other high value materials. We are currently building a prototype for the consumer products industry that will act as a demonstrator for the many other possible applications.”

The rest of the interesting entries can be found on CUE’s website.

Although many techniques exist for preparing microcapsules, it is still challenging to fabricate them in an efficient and scalable process without compromising functionality and encapsulation efficiency. We demonstrated a simple one-step approach that exploits a versatile host-guest system and uses microfluidic droplets to generate porous microcapsules with easily customizable functionality. The capsules comprise a polymer-gold nanoparticle composite held together by cucurbit[8]uril ternary complexes. The dynamic yet highly stable micrometer-sized structures can be loaded in one step during capsule formation and are amenable to on-demand encapsulant release. The internal chemical environment can be probed with surface enhanced Raman spectroscopy.
