If the performance numbers hold, it would remove the need for multi-axial indenters or manual scratching.\n\nThe novelty sits in the specific pairing of routine AFM modes for both nucleation and real-time manipulation, presented as simpler than the specialized systems referenced in the abstract. The description of the steps is direct and the link to NEMS ribbon applications is stated plainly without extra hype.\n\nThe description itself is clear enough that a reader could try the protocol from the text alone.\n\nThe clear weakness is that the abstract states high yields and comparable timeframes with zero supporting evidence. No images, no success rates, no time data, and no comparison to prior methods appear. The central performance claims therefore rest on assertion rather than shown results. This is a methods paper whose value depends entirely on the missing experimental record.\n\nThe work targets researchers who fabricate 2D material structures for nanoelectromechanical devices and who lack access to custom indentation setups. Someone in that narrow group might extract a usable idea, but only after seeing the actual data.\n\nI would not send this to peer review on the basis of the abstract alone. The absence of any results makes it impossible for referees to judge whether the method works as described or how reproducible it is.
