The Drums Of BIO 2015: Dollars, Nano and Data
By Louis Garguilo,
Three sounds among the drumbeat of discussions at BIO 2015 in Philadelphia reverberated most for me.
The first came from the bass drum of money: Investment opportunities, private funding, IPOs, low interest rates ... but darkening macroeconomics. “Partnerships” sounded more like “payerships,” as financiers, biotechs, and specialty and big pharma, search for ways to fund novel ideas and bankroll products through development to commercial.
Next were the razor-sharp tones of the nanotechnology snare drum. With the arrival of nanobio, nanomedicine, and nano-a-lot-of-areas collectively, a third pillar of our part of the healthcare sector has emerged: now it’s Pharma, Bio, and Nano. This maturing technology may redefine what we think of as “medicine,” how we deliver drugs, and fight disease.
And hitting the cymbals with ringing exclamation was “the whole digital field interacting with pharma and bio,” as described by Monika Lessl, Ph.D., VP, Head of Innovation at Bayer AG.
