The challenges and opportunities of open‐access microscopy facilities

Microscopy core facilities are increasingly utilised research resources, but they are generally only available to users within the host institution. Such localised access misses an opportunity to facilitate research across a broader user base. Here, we present the model of an open‐access microscopy facility, using the Advanced Imaging Center (AIC) at Howard Hughes Medical Institute Janelia Research Campus as an example. The AIC has pioneered a model whereby advanced microscopy technologies and expertise are made accessible to researchers on a global scale. We detail our experiences in addressing the considerable challenges associated with this model for those who may be interested in launching an open‐access imaging facility. Importantly, we focus on how this model can empower researchers, particularly those from resource‐constrained settings.
