The “Molecular Imaging in Nanotechnology and Theranostics” (MINT) Interest Group of the World Molecular Imaging Society (WMIS) was founded in 2015 and was officially inaugurated during the 2016 World Molecular Imaging Conference (WMIC). The MINT interest group was created in response to the exponential growth of the fields of Nanotechnology and Theranostics in recent years, and the resulting need to provide a more organized and focused forum on these topics at the WMIS and the WMIC. The overarching goal of MINT is to bring together the many scientists who work on molecular imaging approaches using nanotechnology, and those that work on theranostic agents. MINT therefore represents scientists, labs, and institutes that are very diverse in their scientific backgrounds and areas of expertise, reflecting the wide array of materials and approaches that drive these fields. In this short review, we attempt to provide a condensed overview over some of the key areas covered by MINT. Given the breadth of the fields and the given space constraints, we have limited the coverage to the realm of nano-constructs, although theranostics is certainly not limited to this domain. We will also focus only on the most recent developments of the last 3-5 years, in order to provide the reader with an intuition of what is “in the pipeline” and has potential for clinical translation in the near future.
Cell surface marker expression in tumors dictates the selection of therapeutics, therapy response, and survival. However, biopsies are invasive, sample only a small area of the tumor landscape and may miss significant areas of heterogeneous expression. Here, we investigated the potential of antibody-conjugated surface-enhanced resonance Raman scattering nanoparticles (SERRS-NPs) to depict and quantify high and low tumoral surface marker expression, focusing on the surface markers epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) in an intracerebral and peripheral setting with an inter-and intratumoral comparison of Raman signal intensities.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
