Facile One Pot Synthesis of Hybrid Core-Shell Silica-Based Sensors for Live Imaging of Dissolved Oxygen and Hypoxia Mapping in 3D cell models
Helena Iuele, Stefania Forciniti, Valentina Onesto +6
Fluorescence imaging allows for non-invasively visualizing and measuring key physiological parameters like pH and dissolved oxygen. In our work, we created two ratiometric fluoresc…
A Fluorescent Ratiometric Potassium Sensor Based on IPG4-Silica Microparticles for Selective Detection and Fluorescence Imaging of Potassium Cations
Francesco Colella, Stefania Forciniti, Valentina Onesto +4
Potassium cations play many important roles in living organisms, especially in electro-physiology, since they are involved in neurotransmission and muscle contractions. We report t…
Highly Sensitive Ratiometric Fluorescent Fiber Matrixes for Oxygen Sensing with Micrometer-Spatial Resolution
Giuliana Grasso, Valentina Onesto, Stefania Forciniti +8
Oxygen (O2)-sensing matrices are promising tools for the live monitoring of extracellular O2 consumption levels in long-term cell cultures. In this study, ratiometric O2-sensing me…
A pH Sensor Scaffold for Mapping Spatiotemporal Gradients in Three Dimensional In Vitro Tumour Models
Riccardo Rizzo, Valentina Onesto, Stefania Forciniti +6
The detection of extracellular pH at single cell resolution is challenging and requires advanced sensibility. Sensing pH at a high spatial and temporal resolution might provide cru…
Fluorescent nano- and microparticles for sensing cellular microenvironment: past, present and future applications
Giuliana Grasso, Francesco Colella, Stefania Forciniti +7
The tumor microenvironment (TME) features distinct hallmarks, including acidosis, hypoxia, reactive oxygen species (ROS) generation, and altered ion fluxes, which are crucial targe…
Highly sensitive fluorescent pH microsensor based on the ratiometric dye pyranine immobilized on silica microparticles
Anil Chandra, Saumya Prasad, Helena Iuele +5
Pyranine (HPTS) is a remarkably interesting pH sensitive dye that has been used for plenty of applications. Its high quantum yield and extremely sensitive ratiometric fluorescence…
