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.

This article describes a novel protocol and reagent set designed for sensitive measurement of neurotoxic effects of compounds and treatments on co-cultures of neurons and astrocytes using high content analysis. Results demonstrate that high content analysis represents an exciting novel technology for neurotoxicity assessment.
FAQs
These processes determine where a substance appears, how long it remains, and when its measured levels decline. Transport moves the material between biological compartments, retention produces sustained tissue exposure, metabolism can alter the material, and elimination removes it from the system. Tracking concentrations across time helps distinguish temporary delivery from meaningful accumulation and clearance.
Detectable labels provide a way to locate and quantify administered materials within tissues and organs. Depending on the study, researchers pair these materials with imaging, tissue sampling, or quantitative assays. The resulting measurements connect an engineered product to its biological exposure, making it possible to evaluate whether it reaches intended sites or appears elsewhere.
Delivery route and engineered material properties influence which tissues encounter a product and how strongly it is retained. In bioengineering studies, comparing distribution profiles can reveal whether a nanoparticle, biomaterial, or other carrier supports the intended targeting pattern. These observations guide design changes aimed at improving efficacy while reducing unwanted exposure in other organs.
A study generally administers a labeled or detectable substance, examines selected tissues at defined time points, and measures the material using imaging, tissue sampling, or quantitative assays. Researchers then compare the detected amounts among organs and across time. This workflow produces distribution and clearance profiles that show both localization and changes in exposure.
Bioengineering applications include drug-delivery systems, nanoparticles, biomaterials, gene therapies, and cell-based products. For each product type, measurements help determine whether the engineered system reaches relevant tissues, remains localized, or produces off-target exposure. Such evidence supports refinement of the product and helps connect its physical or biological design with performance in the body.
Distribution data show whether exposure occurs at sites associated with intended activity and whether accumulation appears in other organs. Clearance measurements add information about persistence, while tissue-level comparisons can reveal potential off-target patterns. Together, these outcomes help researchers assess efficacy and safety, optimize engineered therapies, and decide whether a design is sufficiently characterized for further translation.
