OCTA Tutorial: How does OCT Angiography Work? OCTA, also known as OCT angiography, is a non-invasive and dye-free imaging technique that can be used to visualize blood flow in tissues in 3D. It is a variant of optical coherence tomography (OCT), an optical imaging modality first applied in ophthalmology. OCT […]
Can SERS outshine fluorescence as the technique of choice for biosensors? Explore a promising new sensor design for pH, and the impact of hydrogel matrix on performance.
High speed UHR-OCT reaches the cellular level by Cicely Rathmell Recent increases in the speed and resolution of ultrahigh resolution OCT are opening up new possibilities for in-vivo, non-contact imaging of the cellular structure of biological tissue at image acquisition rates high enough to suppress significantly image artifacts arising from […]
Raman shows its strengths for process monitoring in biotechnology as we use PLS and PCA to follow the fermentation of glucose by yeast to generate ethanol with a probe-based 785 Raman system.
