Ultrafast longitudinal imaging of haemodynamics via single-shot volumetric photoacoustic tomography with a single-element detector

Nature Biomedical Engineering, 2023
Techniques for imaging haemodynamics use ionizing radiation or contrast agents or are limited by imaging depth (within approximately 1 mm), complex and expensive data-acquisition systems, or low imaging speeds, system complexity or cost. Here we show that ultrafast volumetric photoacoustic imaging of haemodynamics in the human body at up to 1 kHz can ...

Self‐Assembled (Aza)BODIPY Dyes for Biomedical in Vivo Imaging

Angewandte Chemie International Edition, EarlyView.
This minireview classifies (aza)BODIPY dyes according to their molecular stacking modes and aggregate types (H‐, oblique‐, or J‐type) in aqueous media, correlating these features with their multimodal imaging performance. By linking molecular design, exciton coupling, and pathway‐dependent assembly, we provide a framework for engineering next ...

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks

Chemistry – A European Journal, EarlyView.
A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...
