About 50% of the cellular proteins have to be transported into or across cellular membranes. This transport is an essential step in the protein biosynthesis. In eukaryotic cells secretory proteins are transported into the endoplasmic reticulum before they are transported in vesicles to the plasma membrane.

AbstractNanoporous metal foams (NMFs) have been a long sought‐after class of materials in the quest for high‐surface‐area conductive and catalytic materials. Herein we present an overview of newly developed synthetic strategies for producing NMFs along with an in‐depth discussion of combustion synthesis as a versatile and scalable approach for the ...

We demonstrate the assembly of functional hybrid nanopores for single molecule sensing by inserting DNA origami structures into solid-state nanopores. In our experiments, single artificial nanopores based on DNA origami are repeatedly inserted in and ejected from solid-state nanopores with diameters around 15 nm. We show that these hybrid nanopores can

Nanoporous Thermosetting Polymers
Langmuir, 2005Potential applications of nanoporous thermosetting polymers include polyelectrolytes in fuel cells, separation membranes, adsorption media, and sensors. Design of nanoporous polymers for such applications entails controlling permeability by tailoring pore size, structure, and interface chemistry.

Monolithic Nanoporous Crystalline Aerogels
Macromolecular Rapid Communications, 2013Monolithic aerogels can be easily obtained by drying physical gels formed by linear uncross‐linked polymers. Preparation methods, structure, and properties of these physically cross‐linked polymeric aerogels are reviewed, with particular emphasis to those whose cross‐linking knots are crystallites and, more in particular, crystallites exhibiting ...

The passage of individual molecules through nanosized pores in membranes is central to many processes in biology. Previously, experiments have been restricted to naturally occurring nanopores, but advances in technology now allow artificial solid-state nanopores to be fabricated in insulating membranes.
