Build and operation of a custom 3D, multicolor, single-molecule localization microscope

Area of Science:

• Biophysics
• Optical Microscopy
• Nanotechnology

Background:

• Single-molecule localization microscopy (SMLM) offers high-resolution biological imaging.
• Commercial SMLM systems are expensive and complex to develop, limiting accessibility.
• There is a need for cost-effective, customizable SMLM solutions.

Purpose of the Study:

• To provide a comprehensive guide for building a custom, high-end SMLM setup.
• To detail the assembly, alignment, software integration, and operation of a custom SMLM.
• To enable researchers to establish advanced SMLM capabilities in their labs.

Main Methods:

• Detailed instructions for optical pathway alignment and hardware/software integration.
• Validation procedures using test and biological samples with known structures.
• Guidance on troubleshooting and performance benchmarking of the custom SMLM.

Main Results:

• A functional, high-end SMLM system can be constructed for $95,000-$180,000.
• Construction and optimization require an estimated 4-8 months for experienced builders.
• The guide facilitates the acquisition of high-quality 3D, multicolor super-resolved images.

Conclusions:

• Building a custom SMLM is feasible and significantly more affordable than commercial options.
• This guide empowers researchers to implement advanced SMLM for biological discovery.
• Democratizing access to high-resolution microscopy through open-source, custom-built systems.
