Brief overview of the paper and its main findings

The authors described an interesting study on the biocompatible micromechanical tweezers. As a clinician we are always actively looking for improvements in patient care and advancements in novel biomaterial development. I would like to know: 1. What are some of the potential applications in the medical fields that the authors see in utilizing this new technology? 2. What specially is new about this micro-tweezer in offering hydrogel characterizations? I was not sure how this new technology is different from what is already existing on the market at this time as I do not see a clear advantage to what we are using currently. Thank you
