Adaptive all the way down: Building responsive materials from hierarchies of chemomechanical feedback
Grinthal, Alison Elizabeth; Aizenberg, Joanna (Royal Society of Chemistry (RSC), 2013)A living organism is a bundle of dynamic, integrated adaptive processes: not only does it continuously respond to constant changes in temperature, sunlight, nutrients, and other features of its environment, but it does so ... -
Adaptive fluid-infused porous films with tunable transparency and wettability
Yao, Xi; Hu, Yuhang; Grinthal, Alison Elizabeth; Wong, Tak-Sing; Mahadevan, Lakshminarayanan; Aizenberg, Joanna (Nature Publishing Group, 2013)Materials that adapt dynamically to environmental changes are currently limited to two-state switching of single properties, and only a small number of strategies that may lead to materials with continuously adjustable ... -

Assembly of large-area, highly ordered, crack-free inverse opal films
Hatton, B.; Mishchenko, L.; Davis, S.; Sandhage, K. H.; Aizenberg, Joanna (Proceedings of the National Academy of Sciences, 2010)Whereas considerable interest exists in self-assembly of well-ordered, porous “inverse opal” structures for optical, electronic, and (bio)chemical applications, uncontrolled defect formation has limited the scale-up and ... -
Bacteria Pattern Spontaneously on Periodic Nanostructure Arrays
Hochbaum, Allon I.; Aizenberg, Joanna (American Chemical Society (ACS), 2010)Surface-associated bacteria typically form self-organizing communities called biofilms. Spatial segregation is important for various bacterial processes associated with cellular and community development. Here, we demonstrate ... -
Bacterial biofilm shows persistent resistance to liquid wetting and gas penetration
Epstein, A. K.; Pokroy, B.; Seminara, A.; Aizenberg, Joanna (Proceedings of the National Academy of Sciences, 2010)Most of the world’s bacteria exist in robust, sessile communities known as biofilms, ubiquitously adherent to environmental surfaces from ocean floors to human teeth and notoriously resistant to antimicrobial agents. We ... -
Bacterial Interactions with Immobilized Liquid Layers
Kovalenko, Yevgen; Sotiri, Irini; Timonen, Jaakko; Overton, Jonathan C.; Holmes, Gareth; Aizenberg, Joanna; Howell, Caitlin (Wiley, 2016)Bacterial interactions with surfaces are at the heart of many infection-related problems in healthcare. In this work, the interactions of clinically-relevant bacteria with immobilized liquid (IL) layers on oil-infused ... -
Bio-Inspired Band-Gap Tunable Elastic Optical Multilayer Fibers

Biofilm attachment reduction on bioinspired, dynamic, micro-wrinkling surfaces
Epstein, Alexander K; Hong, Donggyoon; Kim, Philseok; Aizenberg, Joanna (IOP Publishing, 2013-09-27)Most bacteria live in multicellular communities known as biofilms that are adherent to surfaces in our environment, from sea beds to plumbing systems. Biofilms are often associated with clinical infections, nosocomial ... -
Bioinspired Artificial Melanosomes As Colorimetric Indicators of Oxygen Exposure
Shillingford, Cicely; Russell, Calvin W.; Burgess, Ian B.; Aizenberg, Joanna (American Chemical Society (ACS), 2016-02-15)Many industries require irreversibly responsive materials for use as sensors or detectors of environmental exposure. We describe the synthesis and fabrication of a nontoxic surface coating that reports oxygen exposure of ... -
Bioinspired micrograting arrays mimicking the reverse color diffraction elements evolved by the butterfly Pierella luna
England, Grant Tyler; Kolle, Mathias; Kim, Philseok; Khan, Mughees; Munoz, Philip Alejandro; Mazur, Eric; Aizenberg, Joanna (Proceedings of the National Academy of Sciences, 2014)Recently, diffraction elements that reverse the color sequence normally observed in planar diffraction gratings have been found in the wing scales of the butterfly Pierella luna. Here, we describe the creation of an ... -
