About Gustavo Larsen

Dr. Larsen has been a Professor of Chemical and Biomolecular Engineering at the University of Nebraska-Lincoln since 1993. He completed his B.S. in Chemistry from the University of Mar Del Plata (Argentina) in 1985 and his Ph.D. in Chemical and Biomolecular Engineering from Yale University in 1992.

Dr. Larsen has devoted his research career to two broad fields, namely catalysis and adsorption, and the scalable production and testing of nanomaterials for biomedical applications. He is a highly cited author in both areas of materials engineering, and is also an inventor and patent holder of related technologies.

An innovation that is finally catching up: Needleless centrifugal electrospinning (NCES)

Sixteen years ago, Dr. Larsen and his team patented a device that used high-throughput, needleless centrifugal electrospinning (NCES) to make biocompatible ultrafine fibers. With a commercial angle in mind, Dr. Larsen began making nonwoven fibrous mats for hemostasis applications with such a device [1], and at production rates normally two orders of magnitude larger than conventional single-nozzle electrospinning. Automated machines capable of producing rolls of nonwoven fibers were built and used for many years, with funding from the U.S. Army and the Department of Energy. A key innovation was not even a delivery orifice was necessary to produce electrified liquid jets, which just formed from on open liquid surfaces.

In essence, a fiber-forming liquid precursor is fed perpendicularly at the center of a flat metal disk (typically 1-2 in diameter) rotating at high speed (1,000-100,000 rpm). A cylindrical coaxial collector drum, typically about 40-70 cm in diameter is used to deposit the electrospun fibers, as electrified liquid jets are ejected off the edge of the rotating disk and on solvent evaporation, solidification into submicron fibers occur [1]. The disk is also made to move vertically to create a rather homogeneous fibrous layer. Intriguingly, such a device (or straightforward variations of it) have been described in a number of much more recent patents -that we do not need to cite here in the interest of brevity- and showcased as revolutionary innovations, lending credence to the old adage that science and engineering are often plagued with “wheel reinvention”.

As one example, the figures below show nanofibers made using the NCES device from a liquid precursor comprising 15% wt% (poly)lactic acid, MW = 170 kDa (CorbionTM), in ethyl acetate.
A - Feed flow rate: 300 ml/hr, Voltage: 15kV, Rotational speed: 35000rpm
B - Feed flow rate: Voltage: 400 ml/hr, Rotational speed: 20kV, 35000rpm
