  Sensitizer-enhanced two-photon patterning of biomolecules in photoinstructive hydrogels

  Proteins can be patterned in photoresponsive hydrogels by the application of light. Here, a two-photon lithography-based approach allows for the 3D patterning of proteins with micrometer precision, demonstrated for a photoinstructive hydrogel and relevant to a range of proteins.

  Fast and real-time electrical transistor assay for quantifying SARS-CoV-2 neutralizing antibodies

  The COVID-19 pandemic highlights the importance of tests for assessing antibody titer, such as for determining vaccine efficacy. Here, a fast-operating organic electrochemical transistor is shown to assess the cytopathic effect caused by the SARS CoV-2 virus on Vero E6 cells in real-time.

  A transparent waveguide chip for versatile total internal reflection fluorescence-based microscopy and nanoscopy

  Total internal reflection fluorescence microscopy typically relies on opaque optical waveguides, compatible only with upright microscopes. Here, a versatile approach is reported that uses CMOS-compatible transparent chips, demonstrated for the imaging of synthetic and biological samples, including super-resolution applications.
