Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

open access: yesAdvanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels

open access: yesAdvanced Functional Materials, EarlyView.
Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.

Complementary Logic Driven by Dielectrophoretic Assembly of 2D Semiconductors

open access: yesAdvanced Functional Materials, EarlyView.
Scalable, parallel fabrication of complementary logic gates is demonstrated using electric‐field‐driven deterministic assembly of electrochemically exfoliated 2D n‐type MoS2 and p‐type WSe2 nanosheets. This strategy yields MoS2 and WSe2 transistors featuring average mobilities of 4.3 and 3.0 cm2 V−1 s−1, respectively, and on/off ratios of > 104 ...
