Glass pipets composed of quartz or borosilicate possess a long needle-like shape and pore orifice. Also, they have many amazing advantages, including ease of fabrication and low cost, tailorable pore size, and modifiable surface properties. It is the above unique geometrical features and advantages that allow for their numerous applications in the fields of analytical chemistry, 1− 5 material science, 6− 8 and molecular/cell biology. 9 The studies of the glass pipet initially originate from some fundamental works referring to its fabrication and geometrical characterization. Much effort from researchers makes its preparation procedures simplified. Significantly, it enables tailoring the pore size from the microscale down to the nanoscale level. Especially, recent advances allow to a high degree control over the pore size and the achievement of a sub-10 nm nanopipette. 10, 11 Simultaneously, the geometrical characterization of the nanopipette such as pore size and cone angle experiences from a rough estimation by scanning electron microscopy (SEM) 12, 13 and electrical-resistance measurement 14 to directly allow precise characterization by transmission electron microscopy (TEM). 15 Moreover, a further optimization of TEM conditions realized the nondestructive characterization for a sub-10 nm nanopipette. 11 The earliest application of a pipet in physiology referred to the patch clumping technique to detect the membrane potential in the 1970s. Because of this important technique, it won the Nobel Prize for Physiology or Medicine in 1991. 16 After that, with the advances in the fundamental research of pipet fabrication, characterization, and functionalization, they have found many applications in analytical chemistry referring to electrochemical and biosensing 17− 20 and as probes for scanning ion conductance microscopy (SICM), 21 scanning electrochemical microscopy (SECM), 22, 23 and scannig electrochemical cell microscopy (SECCM). 24 In the latest two years, the applications of the glass pipet have expanded to material science in the fabrication of a threedimensional (3D) micro/nanostructure of promising functional materials such as the metal− organic framework (MOF) to understand its dynamics of mass transport and quantitative analysis of nanoparticle size during its formation. 25 This novel method would continuously expand its use for synthesis of other materials and analysis of mass transport in near future. Also, a nanopipette as a probe of SICM allows to noncontact visualize the topography of complex biological samples such as neuros and 3D cells, 26, 27 to quantitatively analyze the ionic environment of bacteria and living cells, 28, 29 and to explore mechanical properties 30, 31 of cells related to cancer diagnosis with high spatial resolution. Moreover, a nanopipette also exhibits remarkable applications in SECM and SECCM for analysis of numerous catalytic reactions, for example, hydrogen/oxygen evolution reaction, 32, 33 of inorganic and biological samples. Furthermore, utilizing the functionalized nanopipette with a nanoelectrode sensor is capable of insight into the redox process in the cell level. 34Mirkin et al. 35 summarized the applications for current resistive-pulse and rectification sensing with glass and carbon nanopipettes in 2017. Shao et al. 36 reviewed the general nanopipette fabrication and its use for chemical analysis in 2018. Therefore, in this Review, we focus on the latest breakthrough in the fabrication, characterization, and filling of sub-10 nm nanopipettes since its potential use in high resolution imaging and sensing. Then, we discuss the amazing applications of a pipet in nanotechnology and nanoscience covering …
