  • hemostatic agent for trauma treatment [107]. Patil et al. explored three types of silk forms, namely, regular film, lamellar porous film, and electrospun silk nanofibers for wound dressings. Factors such as solvent solution, electric field intensity, spinning distance, and SF concentration affected the
  • can be classified as gold–polydopamine blackspheres (AuPBs), capable of absorbing NIR-II light and converting it into heat. These particles were incorporated into an electrospun film by combining poly(ʟ-lactic acid) (PLLA) with SF to obtain a PLLA-SF parallel films. The films had high strength and
