Typical gelation kinetics profile of thiol-ene mixture CollPEG4 (LAP 0.5% (w/v)). Dark grey: storage modulus (G’); light grey: loss modulus (G’’). UV light was activated 60 s after the start of the time sweep measurement, resulting in complete gelation after nearly 300 s. The inner image presents a zoomed-in plot of the initial stage of gel formation, indicating a gel point after just 7 s of UV activation.
