3D rotational digital tomography

DHTM is label-free and records the phase shift of low-energy light passing through the specimen on a transparent surface with minimal perturbation. DHTM measures the refractive index (RI) and computes the refractive index gradient (RIG), unveiling optical heterogeneity in cells. We will analyze blood samples for the detection of altered neutrophil phenotypes and microclots.

Atomic Force Microscopy

The atomic force microscope (AFM) is widely used in materials science and has found many applications in biological sciences but has been limited in use in vision science. The AFM can be used to image the topography of soft biological materials in their native environments. We will analyze blood samples for the detection of altered neutrophil phenotypes and microclots

Micro-Computertomography

"Micro-CT is a 3D imaging technique utilizing X-rays to see inside an object, slice by slice. Micro-CT, also called microtomography or micro computed tomography, is similar to hospital CT or CAT scan imaging but on a small scale with greatly increased resolution. Samples can be imaged with pixel sizes as small as 100 nanometers and objects can be scanned as large as 200 millimeters in diameter. We will use micro-CT to analyze blood clots from patients with large vessel occlusion."
