Preserving Protein Function Via Statistically Random Heteropolymers

Protein-based materials have the potential to change the current paradigm of materials science. However, it still remains a challenge to preserve protein hierarchical structure and function while making them readily processable. Protein structure is inherently fluid, and it is this property that contributes to their fragility outside of their native environment. Through the use of rationally designed statistically random heteropolymers, it is possible to stabilize proteins at each hierarchical level and process them in organic solvents, a common need for materials fabrication. The chemical and architectural complexities of statistically random heteropolymers provide a modular platform for tunable protein-polymer-solvent interactions. This provides opportunities not offered by small molecule surfactants or amphiphilic block copolymers. Through evaluation of horseradish peroxidase and green fluorescent protein structure, we show that statistically random heteropolymers can stabilize enzymes. Allowing for activity retention when stored in organic solvent, over 80% activity was observed after 24 hours. Furthermore, horseradish peroxidase and chymotrypsin proteins, when encapsulated in statistically random heteropolymers, are still accessible to their substrates while remaining inaccessible to the denaturing organic solvent. Statistically random heteropolymers have potential in creating stimuli-reponsive materials and nanoreactors composed of proteins and synthetic materials.

Easy to Wear Dry EEG Sensors for Human–Computer Interactions

Measurements based on electroencephalogram (EEG) are made by placing electrodes over a human scalp to apply and receive electrical signals. Various implementations of EEG sensors are available. The electroencephalogram (EEG) has recently gained popularity for use in various non-clinical studies but still lacks any robust, single application outside well-controlled laboratory environments. As the limitations of EEG are mostly due to the low spatial resolution, using multiple bio-sensing modalities proves to be better performing than EEG alone
