Biopolymer Science


Cell Injection


 

Cell injection is one of the core methods to introduce non-permeable molecules into cells. It allows direct access to the two main intracellular compartments, the nucleus and cytoplasm. The video above shows dye (for visualization) being injected into human dermal fibroblast cells. Cell injection is used in conjunction with AFM and other biophysical imaging techniques to connect the viscoelasticity of cells to overall cell health.
