On electrospun PLA nanofibers for bio-sensing applications

In this study, electrospinning was performed by varying the applied voltage (12-14 kV), flow rate (0.5-0.7 lL/s), and tip-to-collector distance (TCD) (14-16 cm) to produce nanofibers (NF) of polylactic acid (PLA). The scanning electron microscopic (SEM) based analysis reveals the finest NF (ɸ144.0 & PLUSMN; 18.0 nm) were prepared at 14 kV (applied voltage), 0.5 lL/s (flow rate), and 16 cm TCD. The resonating frequency (Rf) (3.332 GHz) has confirmed that PLA-based NF may be used as bio-sensors because of its high flexibility in body-centric applications. The results of the crystallinity, normalized heat, and glass transition temperature (Tg) confirmed the scope of PLA-NF-based sensors in repeated thermal cycles.& COPY; 2023 Society of Manufacturing Engineers (SME).

Automated summary

Electrospinning was used to produce nanofibers of polylactic acid (PLA) by adjusting the applied voltage, flow rate, and tip-to-collector distance. The finest nanofibers with a diameter of 144.0 ± 18.0 nm were prepared at 14 kV, 0.5 lL/s, and 16 cm TCD. The resonating frequency of 3.332 GHz confirmed the suitability of PLA-based nanofibers for bio-sensors in body-centric applications. The results of crystallinity, normalized heat, and glass transition temperature (Tg) supported the use of PLA-NF-based sensors in repeated thermal cycles.
