Boost CRISPR efficiency
A solution to CRISPR’s delivery challenges.
FluidFM technology offers a unique tool for gene editing. The stand-alone system enables to efficiently deliver any kind of soluble compound directly into any adherent or suspension cell. Even when it comes to sensitive and hard-to-transfect cells, or when large cargos have to be delivered, FluidFM nano-injection provides the ideal solution.
Deliver all CRISPR components, or any other cargo, simultaneously and at defined concentration directly into the nucleus whilst maintaining high cell viability. This paves the way to use large templates and to easy multiplex- and stack-editing. The stand-alone system also enables optimization of off-target effects and HDR efficiency as the quantity of injected copies can be calculated and therefore dose/response relationships investigated. The injection process is highly automated and reproducible with an intuitive user interface – perform direct delivery with a simple mouse click.
Higher delivery & HDR efficiency
All CRISPR components are delivered simultaneously and at the right concentration directly into the nucleus. For any cargo & cell type, maintaining high cell viability and paving the way to large genomic editing.
Optimize off-target effects
As the quantity of injected copies can be calculated, dose/response relationships can be investigated and thus off-target mutations minimized.
Easy multiplex & stack editing
A FluidFM nanosyringe can be loaded with 100's of different gRNAs. Biology is the limit.
Inject different cocktails at different time points: >95% of cells survive the injection procedure.
Direct delivery with a simple mouse click.
Automated and reproducible injection process with an intuitive user interface.
Shorter cell line development times
Generate multiple KO clones in two weeks. Monoclonality guaranteed.
1. Injection of multiple gRNAs&Cas9
A fluorescent marker is co-injected into CHO cells to verify successful delivery.
Multiple gRNAs are simultaneously delivered
Injection process maintains >95% viability
2. Isolation of the clone candidate
Selected cells are isolated into separate wells.
Monoclonality proof: visual confirmation of the deposition of a single cell
Isolation process maintains >95% viability
3. Clone expansion and analysis
Monoclonal colonies are expanded and the DNA sequenced. 50% of the colonies show a mutation in all the targeted loci.
Extreme reduction in complexity and development time of modified cell lines starting from few nano-injected cells
Transient expression of target proteins with mRNA
Human Dermal Fibroblast injected with GFP mRNA. 70% of injected cells expressed GFP 24h after injection.
Transient mRNA transfection helps to give fundamental insights on protein functions at a single cell level, such as protein expression and intercellular communication.
mRNA transfection using FluidFM nano-injection results in:
Higher transfection efficiency
Lower cell toxicity

Successful transfection of primary neurons with plasmids
With our system, even primary neurons can be transfected successfully and highly efficiently. The FluidFM nanosyringe directly delivers the complexes into primary neurons - gently and autonomously.
Conventional delivery methods applied to neurons are often inefficient, expensive and toxic to the neuron.
