Abstract:
Cyclic alkynes (e.g., cyclooctynes such as dibenzocyclooctynes) can be photochemically generated from cyclopropenones as disclosed herein. The cyclic alkynes can be reacted (e.g., in situ) with materials having alkyne-reactive groups (e.g., azide groups in a “click” reaction). In preferred embodiments, the generation and reaction of the cyclic alkyne can proceed in the absence of a catalyst (e.g., Cu(I)). These reactions can be useful, for example, for the selective labeling of living cells that are metabolically modified with azido-containing surface monosaccharides, or for light-directed surface patterning.
Abstract:
A method for forming a self-organized monomolecular film, including at least: dissolving an alkylsilane compound having at least an alkoxysilane group or a chlorosilane group at one end of a molecule in an organic solvent having a dielectric constant of 3.0 or more to 6.0 or less to obtain a solution; subsequently coating the solution on a base material or immersing the base material into the solution; and subsequently drying the solution located on the base material.
Abstract:
Sensors, sensing arrangements and devices, and related methods are provided. In accordance with an example embodiment, an impedance-based sensor includes a flexible dielectric material and generates an output based on pressure applied to the dielectric material and a resulting compression thereof. In certain embodiments, the dielectric material includes a plurality of regions separated by gaps and configured to elastically deform and recover in response to applied pressure.
