Capillary Electrophoresis: Instrumentation

Capillary Electrophoresis: Instrumentation

Capillary electrophoresis instrumentation typically consists of several key components. A high-voltage power supply generates the electric field necessary for the separation by connecting to an anode (the positively charged electrode) and a cathode (the negatively charged electrode) located in buffer reservoirs at each end of the capillary tube. The system includes a sample vial, a fused silica capillary tube coated with polyimide for mechanical strength through which the sample components...

Background:

Electrospun nanofiber scaffolds are valuable for accelerating cell maturation, growth, and migration in vitro.
Electrospinning utilizes a charged polymer jet collected on a grounded surface, producing either aligned or randomly oriented nanofibers based on collector speed.

Purpose of the Study:

To present a protocol for setting up a basic electrospinning apparatus.
To guide empirical approximation of the critical entanglement concentration for polymer solutions.
To optimize the electrospinning process for desired nanofiber alignment and morphology.

Main Methods:

Describing the electrospinning process, including the formation and characteristics of the polymer jet (streaming and whipping segments).
Identifying the critical entanglement concentration as essential for stable nanofiber formation.
Explaining how solution composition and apparatus configuration influence jet behavior and resultant fiber morphology.

Main Results:

Observing the streaming segment of the polymer jet provides insights into nanofiber alignment and morphology.
Non-uniform or unstable jets indicate potential issues like poor fiber alignment or beading.
Optimizing the electrospinning process through adjustments leads to improved fiber alignment and morphology.

Conclusions:

This protocol provides a practical guide for researchers new to electrospinning.
Understanding and controlling the electrospinning process is key to fabricating high-quality nanofiber scaffolds.
Troubleshooting common issues is essential for reproducible and effective nanofiber production.
