A bioluminescent probe for longitudinal monitoring of mitochondrial membrane potential

Riccardo Sinisi, Elena Goun, Arkadiy Bazhin, Ghyslain Martial Alain Budin, Tamara Maric

Mitochondrial membrane potential (Delta Psi(m)) is a universal selective indicator of mitochondrial function and is known to play a central role in many human pathologies, such as diabetes mellitus, cancer and Alzheimer's and Parkinson's diseases. Here, we ...

Azacyanine dyes and use thereof

Riccardo Sinisi, Elena Goun, Alma Rosa Morales Morales

The application provides fluorescent dyes, which are cyanine dyes that incorporate additional aza moieties in the indolenium heterocycles and/or in the methine chains connecting them. Symmetrical and unsymmetrical chemically reactive azacyanine dyes are de ...

Bioluminescent-based imaging and quantification of glucose uptake in vivo

Riccardo Sinisi, Elena Goun, Pavlo Khodakivskyi, Arkadiy Bazhin, Aleksey Yevtodiyenko, Tamara Maric, Georgy Mikhaylov

Glucose is a major source of energy for most living organisms, and its aberrant uptake is linked to many pathological conditions. However, our understanding of disease-associated glucose flux is limited owing to the lack of robust tools. To date, positron- ...

Preclinical Evaluation of Photoacoustic Imaging as a Novel Noninvasive Approach to Detect an Orthopaedic Implant Infection

Riccardo Sinisi, Pavlo Khodakivskyi, Ghyslain Martial Alain Budin

Introduction: Diagnosing-prosthetic joint infection (PJI) poses significant challenges, and current modalities are fraught with low sensitivity and/or potential morbidity. Photoacoustic imaging (PAI) is a novel ultrasound-based modality with potential for ...

Compact solid-state CMOS single-photon detector array for in vivo NIR fluorescence lifetime oncology measurements

Edoardo Charbon, Claudio Bruschini, François Eric Powolny, Harald Arjan Robert Homulle, Krisztian Homicsko, Riccardo Sinisi, David Li

In near infrared fluorescence-guided surgical oncology, it is challenging to distinguish healthy from cancerous tissue. One promising research avenue consists in the analysis of the exogenous fluorophores' lifetime, which are however in the (sub-)nanosecon ...

Pre-clinical Evaluation of a Cyanine-Based SPECT Probe for Multimodal Tumor Necrosis Imaging

Riccardo Sinisi

Recently we showed that a number of carboxylated near-infrared fluorescent (NIRF) cyanine dyes possess strong necrosis avid properties in vitro as well as in different mouse models of spontaneous and therapy-induced tumor necrosis, indicating their potenti ...

The Necrosis-Avid Small Molecule HQ4-DTPA as a Multimodal Imaging Agent for Monitoring Radiation Therapy-Induced Tumor Cell Death

Riccardo Sinisi

Purpose: Most effective antitumor therapies induce tumor cell death. Non-invasive, rapid and accurate quantitative imaging of cell death is essential for monitoring early response to antitumor therapies. To facilitate this, we previously developed a biocom ...

Fluorescence lifetime imaging to differentiate bound from unbound ICG-cRGD both in vitro and in vivo

Edoardo Charbon, Claudio Bruschini, François Eric Powolny, Harald Arjan Robert Homulle, Riccardo Sinisi

Excision of the whole tumor is crucial, but remains difficult for many tumor types. Fluorescence lifetime imaging could be helpful intraoperative to differentiate normal from tumor tissue. In this study we investigated the difference in fluorescence lifeti ...
