Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Three-Dimensional Microscopy in Microbiology

Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...

Background:

Nanothermometry offers remote, minimally invasive temperature sensing, crucial for biomedical applications where traditional methods fail.
Current nanothermometry faces limitations in clinical translation due to the lack of 3D thermal imaging and reliance on non-standard equipment.

Purpose of the Study:

To develop a novel nanothermometry technique overcoming current limitations for clinical translation.
To introduce Optical Coherence Thermometry (OCTh) for simultaneous 3D thermal imaging and use of clinically available tools.

Main Methods:

Combined thermoresponsive polymeric nanogels with Optical Coherence Tomography (OCT), a standard 3D clinical imaging modality.
Utilized nanogels' volume phase transition-induced refractive index changes as temperature-sensitive OCT contrast agents.
Validated OCTh's 3D thermal imaging capability in tissue phantoms undergoing photothermal processes, comparing with numerical simulations.

Main Results:

Demonstrated OCTh's ability to generate 3D thermal images in tissue phantoms.
Confirmed the reliability and accuracy of OCTh through comparison with numerical simulations.
Showcased nanogels as effective temperature-sensitive OCT contrast agents.

Conclusions:
