Extracellular vesicles (EVs) contain various bioactive molecules such as DNA, RNA, and proteins, and play a key role in the regulation of cancer progression. Furthermore, cancer‐associated EVs carry specific biomarkers and can be used in liquid biopsy for cancer detection. However, it is still technically challenging and time consuming to detect or isolate cancer‐associated EVs from complex biofluids...
Dip‐pen nanolithography (DPN) is a unique nanofabrication tool that can directly write a variety of molecular patterns on a surface with high resolution and excellent registration. Over the past 20 years, DPN has experienced a tremendous evolution in terms of applicable inks, a remarkable improvement in fabrication throughput, and the development of various derivative technologies. Among these developments,...
This chapter focuses on surface‐bound lipid assemblies generated by two techniques, dip‐pen nanolithography (DPN) and polymer pen lithography (PPL). In recent years, these two methods (and related stamping techniques based on DPN setups) have emerged into sophisticated platforms for the generation of functional lipid assemblies and supported lipid membranes. PPL emerged as a combination of DPN and...
Lipids form the structural and functional basis of biological membranes, and methods for studying their self‐organization in well‐defined nano‐ and micro‐scale model systems can provide insights into biology. Using lipids as an ink for dip‐pen nanolithography (lipid DPN) permits the rapid nanostructuring of multicomponent model lipid membrane systems, but this technique has so far been limited to...
