Chemical and Biological Engineering

The function of the Department of Chemical and Biological Engineering has been to prepare students for the study and application of chemistry in industry. This focus has included preparation for employment in various industries as well as the development, design, and operation of equipment and processes within industry.Through the CBE Department, Iowa State University is nationally recognized for its initiatives in bioinformatics, biomaterials, bioproducts, metabolic/tissue engineering, multiphase computational fluid dynamics, advanced polymeric materials and nanostructured materials.

History
The Department of Chemical Engineering was founded in 1913 under the Department of Physics and Illuminating Engineering. From 1915 to 1931 it was jointly administered by the Divisions of Industrial Science and Engineering, and from 1931 onward it has been under the Division/College of Engineering. In 1928 it merged with Mining Engineering, and from 1973–1979 it merged with Nuclear Engineering. It became Chemical and Biological Engineering in 2005.

Abstract
Glial cell-derived neurotrophic factor (GDNF) is a small protein potently promoting the survival of dopaminergic and motor neurons. GDNF can be secreted from different types of cells including the dopaminergic neural cell line, N27. N27 cells, a rat dopaminergic neural cell line, is regarded as a suitable in vitro model for Parkinson's disease (PD) research. For PD treatment, transcranial magnetic stimulation (TMS), a noninvasive therapeutic method, showed beneficial clinical effects, but the mechanism for its benefit is not understood. Because GDNF is a potent neurotrophic factor, it is of great value to evaluate if GDNF secretion from N27 cells can be affected by magnetic stimulation (MS). However, the current methods for detecting GDNF are time-consuming and expensive. In this paper we outline the detection of GDNF secretion from N27 cells by ultrasensitive nanopore thin film sensors (nanosensor) for the first time. As low as 2 pg/mL GDNF can be readily detected by the nanosensor. Furthermore, we show that MS can promote GDNF secretion from N27 cells. Specifically, the GDNF concentration in N27 cell-conditioned media under MS treatment shows statistically significant increase up to 2-fold after 5 days in vitro in comparison with the control. This nanosensor along with the in vitro PD model N27 cells provides a low-cost, easy-to-use, sensitive approach for studying potential cell biological mechanisms of the clinical benefits of MS on PD.
