  • This PrimeView on 3D extrusion bioprinting accompanies the Primer by Zhang et al. and highlights the main stages of the 3D extrusion bioprinting process.

    PrimeView
  • 3D extrusion bioprinting methods can be used to produce tissue constructs in vitro and in situ and are arguably the most commonly used bioprinting strategies. In this Primer, Zhang and colleagues describe the variants of 3D extrusion bioprinting methods and their specific applications, considerations for the formulation of bioinks and strategies for assessing print quality. The authors conclude by looking to recent and upcoming developments in 4D printing and artificial intelligence-assisted dynamic printing strategies.

  • This PrimeView describes the best practices for using light sheet fluorescence microscopy to image a range of sample types, with a special focus on light sheet properties and image detection.

    PrimeView
  • Light sheet fluorescence microscopy (LSFM) is a technique that uses a thin sheet of light for illumination, allowing optical sectioning of the sample. In this Primer, Stelzer et al. outline the fundamental concepts behind LSFM, discuss the different experimental set-ups for light sheet microscopes and detail steps for processing LSFM images. The Primer also describes the range of applications for this technique across the biological sciences and concludes by discussing advances for enhancing imaging depth and resolution.

  • This PrimeView highlights the best practices for radiocarbon dating of various sample types. Improvements in sensitivity and accuracy allow for dating of rare and precious samples.

    PrimeView
  • Radiocarbon dating is a common and reliable tool for measuring the age of a range of objects, from trees to historical artefacts and human remains. Hajdas et al. outline best practices for selecting and processing samples, as well as obtaining accurate measurements and age ranges. Ethical considerations for rare and culturally valuable materials are discussed.
