Spirometry is the accepted technique for the diagnosis and monitoring of pulmonary disorders. However, the equipment used to perform this test, the spirometers, are mainly based on expensive electronic sensors. On the other hand, optical fiber-based sensors provide an appealing alternative to electronic sensors. To incorporate their advantages into spirometry, two solutions were produced based on different optical fiber technology, fiber Bragg gratings and Fabry-Perot interferometers. The design and implementation of such solutions are described in detail in this book, along with the...

In 2020, cancer led to about 10 million deaths worldwide, with breast cancer showing the highest incidence, especially among women. Cancer imposes vast social and economic costs, and its complexity makes it difficult to predict treatment outcomes. Protein aggregates, which form as treatments destroy cancer cells, may serve as indicators of treatment effectiveness. This book presents a smartphone-based system developed to monitor protein aggregate levels via fluorescence intensity, where fluorophore-stained proteins reflect concentration levels. Initial testing with bovine serum albumin and...
