A New Active Cell Culture Material for Controlled Cell Micro-Manipulation
(2016-05-14)
Mechanical forces in the cell’s natural environment have a crucial impact on growth and behavior, from single-cell gene expression and cell division to the spatial patterning of complex organ architectures. Few areas of ...
Integrated Stimuli-Responsive Functionalities: From Bioseparation to Dynamic Optics
(2016-05-04)
Nature demonstrates the efficiency of hierarchically integrated components that work in cooperation to produce a variety of useful phenomena in organisms, such as movement or shape change. A key feature of these components ...
Reactivity and Selectivity in Aryl C–H Functionalization by Electrophilic Radicals
(2016-05-04)
Two main challenges hinder the development of new, broadly useful C–H functionalization reactions: (1) most C–H bonds constitute part of the relatively inert backbone of an organic molecule, so it is difficult to elicit ...
Sol-Gel Chemistry of Inverse Opals
(2016-04-28)
Controlling nano to microscale structuration enables one to alter a material’s optical, wetting, mechanical, and chemical properties. Structuration on this scale can be formed from spherical building blocks; in particular, ...
Chemical Approaches to the Surface Engineering of Paper and Cellulose-Based Materials for Microfluidics, Electronics and Low-Cost Diagnostics
(2016-01-27)
Paper (and other cellulose-based materials such as cotton thread and fabrics) are underexploited as materials for the construction of “high-tech” and “lab-on-a-chip” devices. One major drawback of paper is its tendency to ...
Peptide-Assisted Nonenzymatic RNA Replication in Coacervate Droplets
(2016-09-14)
Life on earth may have first appeared in the form of a protocell capable of metabolism and containing a self-replicating informational polymer. This polymer was likely to have been RNA due to its ability to serve both as ...
