TL;DR: An optical tweezers-based approach to measure translation, force, rotation, and torque of a kinesin motor with molecular resolution found that the gait followed a rotary stepping mechanism that generates torque and spins cargo.

TL;DR: This work demonstrates for the first time the formation of continuous patterns of nanostructured materials using directed self-assembly under external fields using a tightly focused laser beam in an optical tweezers apparatus with potential for a wide range of applications ranging from solution processed printable electronics to controlled catalysis.

TL;DR: In this article, a supramolecular bound multi-component catalytic material based on a soft oxometalate (SOM) and a porous organic framework (POF) material was designed for site directed suparamolecular heterogeneous catalysis.

TL;DR: In this article, the spin orbit interaction (SOI) of light has been the focus of recent research due to the fundamental consequences and potential applications in diverse systems, ranging from inhomogeneous anisotropic media to engineered plasmonics and metamaterial strutures.

TL;DR: In this article, the authors used hexagonal-shaped upconverting particles and single cells trapped close to a gold-coated glass cover slip in a sample chamber to generate complete 360 degree and continuous pitch motion even with a single optical tweezer beam.
