1：Experimental Design and Method Selection:

The study involved the fabrication of bioPOFs using a rod-in-tube technique and standard heat drawing process. The chemical and optical properties of the polyesters were characterized throughout the fabrication process.

2：Sample Selection and Data Sources:

The study used commercially available polyesters, PDLGA and PDLLA, as starting materials. The optical and chemical properties were measured using various techniques including differential scanning calorimetry (DSC), size exclusion chromatography (SEC), and spectrophotometry.

3：List of Experimental Equipment and Materials:

Equipment included a TA instrument Q2000 DSC device, Waters GPC Alliance 2695 for SEC, Jenoptik HEX04 compression molding machine, Jasco V670-EX Spectrophotometer, Anton Paar Abbemat MW Refractometer, and a standard heat drawing process setup.

4：Experimental Procedures and Operational Workflow:

The preforms were prepared using a rod-in-tube technique and drawn into fibers. The fibers were then characterized for their optical and chemical properties, and their degradation in phosphate-buffered saline (PBS) was studied.

5：Data Analysis Methods:

The data were analyzed using standard techniques for optical and chemical characterization, including cutback measurements for attenuation, SEC for molecular weight determination, and DSC for thermal properties.
