A variety of fluorescent nanoparticles have been developed for demanding applications such as optical biosensing and fluorescence imaging in live cells. Silica-based fluorescent nanoparticles offer diverse advantages for biol. applications. For example, they can be used as labeling probes due to their low toxicity, high sensitivity, resolution, and stability. In this research, a new class of highly fluorescent, efficient nanoparticles composed of a newly synthesized poly[di(2-methoxy-5-(2-ethylhexyloxy))-2,7-(9,9-dioctyl-9H-fluorene)] (PDDF) core and a silica shell (designated as PDDF@SiO2) were prepared using a simple reverse micelle method, and their fluorescent properties were evaluated using methods such as single-dot photoluminescence measurements. The enhanced photostability of the particles and their potential applications for bioanal. are discussed in this article. The morphol., size, and fluorescent properties for prepared PDDF@SiO2 nanoparticles were characterized using transmission electron microscopy (TEM), SEM (SEM) and photoluminescence spectroscopy. The prepared particles size, which was approx. 60 nm, resulted in an excellent colloidal stability in a physiol. environment. The photobleaching dynamics, total numbers of emitted photons (TNEP) and statistical measurements of individual nanoparticles were observed using laser scanning fluorescence microscopy to assess the structure and photostability of PDDF@SiO2 nanoparticles. Addnl., PDDF@SiO2 nanoparticles were used in cell toxicity and permeation tests for biol. analyses, demonstrating a great potential for use as powerful, novel materials within the emerging fields of biosensing and biomedical engineering. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).COA of Formula: C15H24O2
