Congratulations Alanna!

We’re happy to announce that Alanna Stull has passed her Masters thesis defense! Her research focused on controlling the structure and properties of engineered living materials. She modulated cell surface display through environmental factors and brought great insight into our materials. We’re excited to see what the next phase of her career brings!

Celebrating Esther!

We toasted to Esther and all the other NSF Graduate Research Fellowship Program recipients (with cake!) at Rice U. on Nov. 3. This fellowship is highly selective and we are very proud of Esther for her achievement. Support for a student like Esther is a big win for the field of engineered living materials!

New pub! Real-time bioelectronic sensing of environmental contaminants

Congratulations Lin, Josh, and Xu on their publication in Nature! This endeavor overcame challenges in biology and material science to create a specific, rapid bioelectronic sensor. With a detection time of minutes, this technology enables real-time monitoring of low concentration contaminants in water before they become irreversible, and is substantially faster and cheaper than fluorescence-based biosensors and liquid chromatography monitoring. To achieve this, the team engineered a synthetic electron transfer chain that pulls in proteins from four different organisms into E. coli, includes a post-translational gate to overcome rate limitations, and encapsulates the cells and electrode in conductive nanomaterials to improve signal to noise ratios. Proof of concept was demonstrated on thiosulfate and the endocrine disruptor 4-hydroxytamoxifen in environmental water samples, but the concept is applicable to a wide array of contaminants. Spanning the labs of Caroline Ajo-Franklin, Joff Silberg, and George Bennett, between Lawrence Berkeley National Lab and Rice University, this was truly a collaborative effort (our favorite kind)!

New post-doc position available!

We’re seeking a collaborative, curious post-doc to join our Biomaterials team. As we’re a very multidisciplinary group, the position is open to those with backgrounds in biochemistry, bioengineering, materials science, microbiology (C. crescentus experience a plus!), molecular biology, or related field. The main qualification is a strong interest in engineered living materials and their applications! Check out the flyer below for more information and contact us.
