Details
Single-cell targeting with direct delivery into the nucleus or cytoplasm
- Select cells for delivery while observing under a microscope and deliver substances into the nucleus or cytoplasm of targeted cells.
- Easy Control of XY-position and automatic control of delivery Z-position in software.
Minimal damage to cells
- The nanopipette is a glass pipette with minimum tip outer diameter of several tens of nanometers, minimizing damage to cells.
- Delivery with high cell viability enables live single-cell analysis.

Automated, high speed, and high success rate
- The SU10 uses automated cell surface detection, insertion, and delivery to the cell. The process takes approximately 10 seconds with a 90% success rate. (Experiment by Yokogawa)
- Operations previously performed manually by experienced researchers are much more manageable with SU10.
Nano-point Sampling
A very small amount can be sampled from a specific part of the cell.
Collected samples can be used in applications such as genetic analysis.

Webinar : Nanopipette Technology - A New Tool for Single-Cell Analysis
Our primary focus is introducing a newly developed single-cell manipulation platform (SU-10) using a nanopipette for single-cell injection into living cells. This newly developed technology positions its nanopipette with nanoscale precision, allowing injection and/or aspiration of minute amounts of material into and from individual cells without comprising cell viability. Furthermore, we will display our strategy to develop this new product for single-cell-omics and how this nanopipette technology can analyze multiple analytes, including DNA, RNA, proteins, and other small molecules in basic research or drug discovery.

Operation Principle
Automatic cell detection and penetration is a SICM* based technology.
Delivery of solutions and substances into cells is performed by electro-osmosis and electrophoresis.
Q&A
Q1. How is it different from a microinjection system?
A1. The SU10 lowers the damage to a cell with the nanopipette because its tip size is less than 1/10 of a tip used for microinjection.
Automatic detection of cell surface enables a high success rate of insertion to the intended depth of a cell.
The delivery operation uses an electrical method rather than pneumatic or hydraulic pressure.
Q2. How is it different from traditional transfection methods (e.g. transfection reagents, electroporation)?
A2. The SU10 can deliver materials into the selected cells.
The SU10 enables direct delivery of reagents into the cytoplasm or nucleus.
Q3. How is it different from electroporation?
A3. In addition to the above-mentioned “difference from traditional transfection methods”, due to automated cell surface detection, the suspension of cells is not required during injection.
Q4. What is the max volume of injection into the cell?
A4. It is estimated to be tens of femtoliter (fL) per second (1fL=1x10-15L).
The volume can be changed by software settings.
* The delivery volume may vary depending on the solute and vehicle.
Q5. Is the nanopipette disposable?
A5. Yes, but one nanopipette can deliver to 50 cells or more*.
* Experiment using HeLa cells by Yokogawa.

The SU10 is able to directly deliver substances of interest into single cell (nucleus or cytoplasm), using a “nano” pipette with a tip outer diameter of only a few tens of nanometers. This allows fluorescent labeling of live cells and live cell imaging immediately after delivery of the substance, which is not possible with conventional methods. In this application note, we will demonstrate the use of the SU10 for introducing a fluorescent reagent into a cell with low membrane permeability and monitor the intracellular dynamics with the CSU-W1 confocal scanner unit.
The SU10 is a novel technology that can deliver target substances into cells (nucleus or cytoplasm) by using a "nano" pipette made of glass capillary with an outer tip diameter of just tens of nanometers.
The SU10 is able to directly deliver substances of interest into single cells’ nuclei or cytoplasm, using a “nano” pipette with a tip outer diameter of only a few tens of nanometers. Fish epithelial keratocytes have been used in many studies of cell motility because of their constant cell shape during their high speed movement. However, these cells cannot be subcultured , which makes it difficult to introduce reagents and genes using conventional methods, such as electroporation.
In this application note, we will demonstrate the use of the SU10 for introducing plasmids and a low membrane permeability fluorescent reagents into keratocytes and the use of the CSU confocal scanner unit for monitoring the cells.

The SU10 is a “nano” pipette with a tip outer diameter of only a few tens of nanometers, which can automatically deliver target substances into cells (nucleus, cytoplasm) at the single-cell level. The SU10 can directly deliver genome editing tools into the nucleus, so it is expected to enable efficient genome editing. In this application note, we will introduce a case study in which Cas9 RNP and donor DNA were delivered into cells using SU10, resulting in the successful knockout (KO) and knock-in (KI) of target genes.
