The results of the ACS Out of the Box (OOTB) grant were announced during our Annual symposium on December 10th 2025. We are very happy to share the great news that three projects have been awarded the ACS OOTB grant 2025 worth €50,000 per grant.

Measuring the unmeasurable: resonance Raman laser spectroscopy for measurement of organ mitochondrial oxygen pressure

Oxygen is essential for organ function in the human body. Currently, no technique exists that doctors can use to monitor whether the organs receive enough oxygen. Through a unique collaboration between the intensive care, the Laboratory of intensive care medicine and anaesthesiology and the Biomedical photonics group, we will develop a prototype resonant Raman spectroscopy setup to measure intracellular oxygen levels. Light-based oxygen measurements will be performed in skin and organs in healthy and diseased state. This method could ultimately enable clinicians to determine whether the organs receive enough oxygen. This information can prevent organ damage and assist in treatments.

Exercise versus passive hyperthermia versus combined heat + exercise in Brugada Syndrome: clinical, biochemical, and immune signatures in the VU Climate Chamber

Current European and American guidelines recommend that Brugada syndrome (BrS) patients should avoid sports associated with increased core temperature, such as strenuous activity in hot or humid conditions. This restrictive sports advice is based on pre-clinical data and clinical data in Brugada patients with fever related hyperthermia. This study addresses that evidence gap by investigating whether exercise, passive hyperthermia, or the combination provoke relevant ECG changes associated with arrhythmogenic risk in BrS. Using the VU climate chamber, BrS patients and controls will undergo controlled heat and exercise protocols with continuous ECG and biomarker monitoring. By differentiating the effects of exertion versus temperature, this interdisciplinary project aims to clarify temperature-related arrhythmia mechanisms and enable personalized, evidence-based sports recommendations for BrS patients

Establishing a Living Myocardial Slice Platform for Cardiac Disease Modeling and Therapy Testing

This project will establish and standardize a living myocardial slice (LMS) platform at Amsterdam UMC (AMC and VUmc) to study and treat heart disease using human and pig cardiac tissue. These thin, living slices preserve native heart structure and function, enabling precise testing of therapies under near-physiological conditions. The project will harmonize protocols across both centers and model doxorubicin-induced cardiotoxicity with and without SGLT2 inhibitors. Using single-nuclei RNA sequencing, we will map the molecular responses of human heart tissue to these treatments. This innovative, collaborative platform will accelerate translational research and reduce dependence on animal models at AUMC.

Out of the Box (OOTB) Grant
The ACS Out of the Box (OOTB) grant is for ACS researchers who want to start a new translational collaboration within ACS, for example between preclinical and clinical researchers, and use this grant to strengthen grant application(s) in the near future. Possible options for applications: proof of concept experiments, costs for unique (expensive) imaging or genetics studies or any other innovative ideas which will improve future grant applications. The maximum budget requested per OOTB project can be €50,000. Read more about the grant and future grant call here.
