Spark Analysis Detection
Source Code / Test Data
The material here is based on the algorithm described in Mark-Anthony Bray, Nicholas A. Geisse and Kevin Kit Parker, “Multidimensional detection and analysis of Ca2+ sparks in cardiac myocytes,” Biophysical Journal, 92(12): pg 4433 – 4443 [Link].
Movie (supplemental data) – Movie recorded from an isotropic monolayer of neonatal rat cardiac myocytes, loaded with the Ca2+ sensitive dye Fluo-4. The tissue exhibits several tissue-wide calcium transients, accompanied by spark activity.

Welcome Dr. Cera and Dr. Lee! April 3rd, 2017
The DBG would like to extend a warm welcome to our new postdoctoral fellows, Luca Cera & Keel Yong Lee. Luca comes to us from Berlin, German, where he recently completed his Ph.D. in Chemistry under the guidance of Prof. Dr. Christoph A. Schalley. Keel Yong recently completed his Ph.D. in Prof. Kwanwoo Shin’s lab at Sogang University in Seoul, South Korea. We are looking forward to expanding on our past collaborations with him.
Congratulations to Karaghen Hudson, Leila Deravi & Nina Sinatra on the cover of Macromolecular Materials and Engineering! March 27th, 2017
Parker Lab Artist Karaghen Hudson’s illustration accompanying Leila Deravi & Nina Sinatra’s paper “Design and Fabrication of Fibrous Nanomaterials Using Pull Spinning” was chosen for the March 2017 cover of Macromolecular Materials and Engineering.
Pull spinning is a new nanofiber manufacturing technique that uses a high-speed rotating bristle to draw anisotropic nanofibers from a polymer solution. The versatile structure and composition of scaffolds formed using pull spinning enables a wide range of applications, including muscle tissue engineering and textile design.
