Abstract

 The far-reaching goal of the Research is to develop novel approaches towards multifunctional endoscopy, based on light and particles transport inside hollow core photonic crystal fibers. Several essential tools have to be developed on pathways to reach the visionary goal. First, a drug delivery platform must be investigated. In contrast to existing carriers, our nanoparticle shall encompass several functions, including high load capacity, tunable optical properties to control light-matter interactions, and the capability to image the process in real time by following a scattered light or a fluorescent signal. In addition, all constitutive materials should be biocompatible, setting additional constraints on the design. After developing the carrier, hollow-core fiber, serving as a delivery tool, has to be designed. The inner core of the fiber can be functionalized to improve particle guiding properties and, furthermore, grant his platform with additional capabilities, e.g., sensing. Following those general objectives, we have developed a number of tools, which form the core of the thesis. Specifically, we have developed (i) a nano-cargo platform with controllable optical properties, (ii) fiber’s inner core functionalization techniques, (iii) new highly fluorescent biocompatible materials, and (iv) investigated the impact of biogenic particles on living organisms.
