This research explores the influence of geometric configuration on Förster Resonance Energy Transfer (FRET) efficiency. Specifically, it compares spherical arrangements (relevant to structures like nanoparticles) with planar arrangements (found in systems like cell membranes). A key goal is to clarify the interplay between FRET efficiency, inter-molecular distances, and the characteristic Förster distance. By employing both mathematical models and visual representations, the study seeks to provide a detailed understanding of how FRET operates under these distinct geometric constraints. The findings are intended to be broadly applicable, offering valuable insights for the design and analysis of FRET-based experimental work across diverse scientific disciplines.
