Fig. 5: Compatibility of the THFOW with organisms.

a Swelling behavior (n = 3 independent experiments) and (b) mechanical properties (n = 5 independent experiments) of the fabricated THFOWs, data in (a) and (b) were presented as mean ± SD; (c) Comparison of mechanical properties among the THFOW, tissues and other light-guide fibers; (d) Laser light (λ = 515 nm) propagation within porcine tissue through implanted THFOW2500, scale bar = 1 cm. e Live/dead assay of Hela cells on THFOWs compared to blank at 1 and 3 days, where live cells are in green, Scale bars: 100 μm. A representative image of three independent samples from each group is shown in e.
