The characterization of newly synthesized materials is a cornerstone of all chemistry and nanotechnology laboratories. For this purpose, a wide array of analytical techniques have been standardized and are used routinely by laboratories across the globe. With these methods we can understand the structure, dynamics and function of novel molecular architectures and their relations with the desired performance, guiding the development of the next generation of materials. Moreover, one of the challenges in materials chemistry is the lack of reproducibility due to improper publishing of the sample preparation protocol. In this context, the recent adoption of the reporting standard MIRIBEL (Minimum Information Reporting in Bio-Nano Experimental Literature) for material characterization and details of experimental protocols aims to provide complete, reproducible and reliable sample preparation for the scientific community. Thus, MIRIBEL should be immediately adopted in publications by scientific journals to overcome this challenge. Besides current standard spectroscopy and microscopy techniques, there is a constant development of novel technologies that aim to help chemists unveil the structure of complex materials. Among them super-resolution microscopy (SRM), an optical technique that bypasses the diffraction limit of light, has facilitated the study of synthetic materials with multicolor ability and minimal invasiveness at nanometric resolution. Although still in its infancy, the potential of SRM to unveil the structure, dynamics and function of complex synthetic architectures has been highlighted in pioneering reports during the last few years. Currently, SRM is a sophisticated technique with many challenges in sample preparation, data analysis, environmental control and automation, and moreover the instrumentation is still expensive. Therefore, SRM is currently limited to expert users and is not implemented in characterization routines. This perspective discusses the potential of SRM to transition from a niche technique to a standard routine method for material characterization. We propose a roadmap for the necessary developments required for this purpose based on a collaborative effort from scientists and engineers across disciplines.

Dr Shikha Dhiman obtained her MS in Chemical Science (2017) and PhD in Organic and Supra- molecular Chemistry (2020) from Jawaharlal Nehru Centre for Advanced Scientic Research (JNCASR, India) on the theme of structural and temporal control over supramolecular materials. Since 2020, she has been pursuing her postdoctoral research at Eindhoven Univer- sity of Technology (TU/e, The Netherlands) and has been awarded an ICMS fellowship. She has received a Marie Skłodowska-Curie Eurotech fellowship for joint postdoctoral research with TU/e and Technische Universität München, Germany. Her research focus is on application of super-resolution microscopy to unravel cell–material interactions for rational design of supramolecular biomaterials as stem-cell matrices.
