    In current stretchable electronic devices, connection points between modules are made using commercially available pastes and break easily under mechanical deformation. An innovative connection interface has been developed to enable robust stretchable devices to be reliably assembled in a Lego‑like manner by simply pressing the interfaces of two modules together without pastes.

    When circularly polarized light hits an array of chiral gold nanoparticles, it generates polarized electric and magnetic waves across the surface of the nanoparticles. Chiral molecules can alter these resonances, providing a highly sensitive method to determine and quantify molecular chirality, even at very low concentrations.
