Fundamental aspects and state-of-the-art results of thermal scanning probe lithography(t-SPL)are reviewed here.t-SPL is an emerging direct-write nanolithography method with many unique properties which enable original or improved nano-patterning in application fields ranging from quantum technologies to material *** particular,ultrafast and highly localized thermal processing of surfaces can be achieved through the sharp heated tip in t-SPL to generate high-resolution *** investigate t-SPL as a means of generating three types of material interaction:removal,conversion,and *** of these categories is illustrated with process parameters and application examples,as well as their respective opportunities and *** intention is to provide a knowledge base of t-SPL capabilities and current limitations and to guide nanoengineers to the best-fitting approach of t-SPL for their challenges in nanofabrication or material *** potential applications of nanoscale modifications with thermal probes still wait to be explored,in particular when one can utilize the inherently ultrahigh heating and cooling rates.

Liver cirrhosis is the end-stage of chronic progressive liver diseases(1).The most common causes of cirrhosis worldwide include alcohol-related liver disease,non-alcoholic fatty liver disease,hepatitis B,hepatitis C,autoimmune liver diseases(e.g.,autoimmune hepatitis),cholestatic liver diseases(e.g.,primary biliary cholangitis,primary sclerosing cholangitis),hemochromatosis or Wilsons’disease(1).
