PURPOSE: To evaluate the potential of targeted photoacoustic imaging as a noninvasive method for detection of follicular thyroid carcinoma. EXPERIMENTAL DESIGN: We determined the presence and activity of two members of matrix metalloproteinase family …

The polyelectrolyte microcapsules that can be accurate either visualized in biological media or in tissue would en- hance their further in vivo application both as a carrier of active payloads and as a specific sensor. The immobiliza- tion of active …

Herein we report the design and synthesis of multifunctional VEGF-loaded IR800-conjugated graphene oxide (GO-IR800-VEGF) for multi-modality imaging-monitored therapeutic angiogenesis of ischemic muscle. The as-prepared GO-IR800-VEGF positively targets …

Objective: To use a non-invasive measurement of oxygen saturation in chronic leg ulcers after the application of a topical haemoglobin spray to investigate if photoacoustic tomography is able to measure the oxygen saturation and if the stimulated oxygen …

Improved imaging modalities are critically needed for optimizing stem cell therapy. Techniques with real-time content to guide and quantitate cell implantation are especially important in applications such as musculoskeletal regenerative medicine. Here, …

Objectives: We have developed a relevant preclinical model associated with a specific imaging protocol dedicated to onco-pharmacology studies in mice. Materials and Methods: We optimized both the animal model and an ultrasound imaging procedure to follow …

Photoacoustic imaging provides high-resolution images at depths beyond the optical diffusion limit. To broaden its utility, there is need for molecular sensors capable of detecting environmental stimuli through alterations in photoacoustic signal. …

Despite the effort of developing various nanodelivery systems, most of them suffer from undesired high uptakes by the reticuloendothelial system, such as liver and spleen. Herein we develop an endogenous phosphatase-triggered coassembly strategy to form …

In this work, we utilized photoacoustic imaging (PAI) with co- registered ultrasound (US) to non-invasively assess salivary gland function in vivo. A significant increase in salivary gland oxygen saturation was observed on PAI within minutes after …

Objective . Sentinel node biopsy in patients with cutaneous melanoma improves staging, provides prognostic information, and leads to an increased survival in node-positive patients. However, frozen section analysis of the sentinel node is not reliable and …
