Researchers at Linköping University, Sweden, have developed a new type of pipette that can deliver ions to individual neurons ...

SICM measures the ion current flowing through a small glass pipette to map the topography and conductivity of biological samples in a liquid environment, providing insights into cellular structures ...

Somewhat simplified, you can say that the pipette is manufactured by heating up a glass tube and pulling it to the breaking point. This produces a very thin and tapered tip. This type of ...
