Bio-Based Electrospun Nanofiber of Polyhydroxyalkanoate Modified with Black Soldier Fly’s Pupa Shell with Antibacterial and Cytocompatibility Properties
No full textWe report on the antibacterial and cytocompatibility
properties of a bio-based electrospun polyhydroxyalkanoate (PHA) nanofiber
modified with Black Soldier Fly (BSF) pupa shell. A 5–50 μm
chitosan powder (CSP) was made by grinding BSF pupa shell in water,
acid, alkali. CSP was combined with PHA in an electrospinning machine
using a biaxial feed method and manufactured into a 50–500
nm antibacterial nanofiber. We studied the morphology, mechanical
properties, water absorption, and antibacterial properties of the
electrospun PHA/CSP nanofiber. To improve the fiber’s compatibility
and functionality, acrylic acid (AA) was grafted onto PHA. The resulting
tensile properties and morphological characterizations indicated enhanced
adhesion between CSP and PHA-g-AA nanofiber, as well
as an improvement in its water resistance and tensile strength, compared
with the PHA/CSP nanofiber. To study the cytocompatibility of the
material, human foreskin fibroblasts were seeded onto the nanofiber
specimens with 3.0 and 6.0 wt % CSP. Increasing the CSP content in
PHA/CSP and PHA-g-AA/CSP nanofibers enhanced cell
proliferation; additionally, the nanofibers with CSP showed strong
inhibition of bacteria. The enhanced antibacterial and biodegradable
properties of PHA-g-AA/CSP and PHA/CSP nanofibers
demonstrate their potential for biomedical material applications
