Optics and photonics

Definition

Optics and photonics is the study of the fundamental properties of light and harnessing them in practical applications. Optics and photonics covers the entire electromagnetic spectrum from high-energy gamma rays and X-rays, through the optical regime of ultraviolet, visible, and infrared light, to long-wavelength microwave and radio waves.

    Topological defects in a turbulent active nematic on a toroidal surface are shown to segregate in regions of opposite curvature. Simulations suggest that this behaviour may be controlled — or even suppressed — by tuning the level of activity.

    Current strategies for producing antibody-drug conjugates often rely on inefficient conjugation chemistry or on generating mutations in the antibody sequence. Here the authors demonstrate a mutation-free, single-step conjugation platform utilizing a buried lysine residue.

    Piezoelectrics and ferroelectrics are important for everyday applications, but methods to characterize these materials at the nanoscale are lacking. Here the authors present direct piezoelectric force microscopy, an AFM mode that can measure charges generated by the direct piezoelectric effect with nanoscale resolution.

    Understanding the interaction of nanomaterials and immune cells at the biomolecular level is of great significance in therapeutic applications. Here, the authors investigated the interaction of graphene oxide nanomaterials and several immune cell subpopulations using single-cell mass cytometry and genome-wide transcriptome analysis.
