Details
Accurate Positioning
Long stroke movements and accurate positioning enabled by combining stepping motors and piezo electric actuator.
Automatic Cell Detection and Penetration
Automatic cell detection and penetration with ion current measurement.
Injection Method
Utilizes electro-osmotic flow in the tip of the nanopipette to create a pump effect. The amount of injection is controlled by the duration of the voltage pulse application.
Automated Injection Process
Automatically perform approach, surface detection, injection and retraction of the tip of the nanopipette.
Application Example
- Direct injection of substances such as vector and genome editing tools (CRISPR/Cas9) into the nucleus
- Efficacy/toxicity evaluation of drug candidate molecules
- Other physical injection of reagents and proteins
Fast Injection with High Success Rate
By automating the steps to penetrate the target cell, an injection speed of approximately 10 seconds has been achieved.
Fluorescence was observed in 208 out of 220 (94.6%) HeLa cells where the fluorescent protein was injected (experiment by Yokogawa)
Below: RFP was injected into the HeLa cells, and sequentially observed with fluorescence.
Low-Invasive Injection
The extremely small tip diameter of the nanopipette minimizes damage to the target cell.
Below: RFP was injected into the HeLa cells, and sequentially observed with fluorescence.
