Background:

Nonviral gene transfection methods often lack precise spatial control.
Targeted delivery of molecules to specific neurons is crucial for research and therapeutics.

Purpose of the Study:

To present a microelectrode array (MEA) system for precise spatial control of nonviral gene transfection.
To optimize microelectroporation parameters for efficient and viable transfection of primary neurons.

Main Methods:

Utilized a microelectrode array (MEA) system for targeted delivery of exogenous molecules.
Employed microelectroporation with optimized electrical parameters (4 V, 1 ms cathodic pulse).
Transfected small interfering RNA (siRNA) molecules into cultured primary neurons.

Main Results:

Achieved a transfection efficiency of 56% in targeted primary neurons.
Maintained a cell viability of 82% post-transfection.
Demonstrated successful transfection of siRNA molecules into specific neurons.

Conclusions:

The MEA system enables precise spatial control for nonviral gene transfection in neurons.
Optimized microelectroporation parameters provide high efficiency and viability.
This technique is suitable for targeted delivery of nucleic acids like siRNA to primary neurons.
