Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut Nanoparticles have been increasingly used research towards targeted drug delivery and controlled drug release. While most of these particles have been developed as polymeric or liposomal particles because of their biocompatibility, there is a trend in current research toward the use of metallic and magnetic nanoparticles. These metallic nanoparticles...

2025
This video demonstrates an in vivo immunofluorescence localization (IVIL) technique to study the biodistribution of tumor-targeting antibodies in a murine model of breast cancer. Upon the intravenous injection of a tumor-specific antibody in the mouse, the tumor is surgically isolated, and the localization of the antibody within the tumor tissue is confirmed via ex vivo immunostaining.

This work describes methods to establish acute and chronic hyperglycemia models in zebrafish. The aim is to investigate the impact of hyperglycemia on physiological processes, such as constitutive and injury-induced neurogenesis. The work also highlights the use of zebrafish to follow radiolabeled molecules (here, [18F]-FDG) using PET/CT.

Organic Compounds

All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...
FAQs
Organ biodistribution patterns emerge from the interaction of absorption, circulation, vascular permeability, tissue uptake, and clearance. These processes determine how much of a substance remains available in circulation, which organs it can access, and how strongly tissues retain it. Consequently, substances used for similar therapeutic purposes may show different organ profiles, influencing their biological effects and safety.
The liver and kidneys influence organ biodistribution through clearance, which removes substances from the body or changes their exposure over time. Their activity can reduce the amount available to other tissues while also contributing to organ-specific accumulation. Examining these organs helps researchers recognize clearance-related distribution patterns and identify possible off-target exposure relevant to safety assessment.
Vascular permeability affects how readily a substance can move from the circulation into an organ or tissue, while tissue uptake affects how much enters or remains associated with that site. Together, these factors help explain why exposure differs among organs. Their contribution is especially important when researchers assess whether a treatment can reach its intended biological location.
Researchers measure organ biodistribution using imaging, tissue analysis, or labeled compounds. Imaging can show where a substance is located, whereas tissue analysis examines distribution within collected biological material. Labeled compounds provide a way to track the substance across organs. These approaches generate evidence about intended-site exposure and reveal accumulation in organs that may not be therapeutic targets.
Using imaging, tissue analysis, or labeled compounds allows researchers to examine distribution from complementary perspectives. The resulting measurements can show whether a substance reaches relevant organs and whether it accumulates elsewhere. Interpreting these patterns alongside absorption, circulation, tissue uptake, and clearance helps connect observed organ exposure with the biological behavior of a treatment or carrier.
Biodistribution findings show whether a drug or therapeutic carrier reaches the intended site and how much exposure occurs in other organs. Researchers can use this information to refine drug delivery design, evaluate whether distribution supports the desired treatment effect, and guide dose selection. The same evidence can also identify distribution patterns that raise safety concerns.
Distribution patterns help researchers compare treatment exposure across tissues and evaluate whether a therapy is likely to act where needed. Studying these patterns in different disease models supports interpretation of treatment efficacy under varied biological conditions. The findings also help connect tissue exposure with safety, dose selection, and the likelihood that a therapeutic approach will perform as intended.
