High-Speed Quasi-Distributed Optical Fiber Sensing Based on Ultra-Weak Fiber Bragg Gratings
… and high-speed sensing by employing serial ultra-weak fiber Bragg gratings (UW-FBGs) and dispersive components. Various factors which have influence on the system performance, including wavelength resolution, spatial resolution and sensing rate, are analyzed. Different types of light sources …

Light in Living Systems: Ultra-Weak Photon Emission and Fluorescence Lifetime Imaging of Cellular Dynamics
Ultra-weak photon emission (UPE) is a phenomenon intrinsic to oxidative metabolism, yet its detection and biological role remain contested. This thesis bridges theoretical, technical, and biological perspectives to advance the study of cellular light. Part I provides a critical review of UPE, …

A Quasi-distributed Sensing Network Based on Wavelength-Scanning Time-division Multiplexed Fiber Bragg Gratings
… maintenance free or minimum maintenance, ultra-low cost per measurement point, and capability of operation in harsh environments. Fiber Bragg grating (FBG) has attracted considerable interest for this application because of its compactness, electromagnetic immunity, and excellent …

The role of Biophotons in cellular senescence.
… mitochondrial respiration, are known to emit ultra-weak photons (biophotons), primarily generated through ROS production. There is increasing evidence that cells can influence each other non-chemically via biophotons. In this study, I aim to elucidate the potential impact of both intrinsic …

In vitro studies on new therapeutic approaches for human thyroid cancer
… correlation between apoptosis and UVA induced ultra-weak photon emission (Delayed Luminescence, DL) from tumor thyroid cell lines was investigated. In particular, it has been studied the effects of Berberine, an alkaloid that has been reported to have anticancer activities, on FTC-133 and 8305C …

Protein folding in living cells and under pressure
… the intracellular environment and the role that ultra-weak “quinary” interactions play inside living cells is presented in chapter 4, which also includes a review of the most recent literature studying biomolecular dynamics in their native environments. In chapter 5 we study the time-dependence …
