Biological, Chemical, and Electronic Applications of Nanofibers

Abstract

With their high‐surface‐to‐volume ratio, nanofibers have been postulated to increase interactions between nanofibrous materials and targeted substrates, which are helpful to overcome many obstacles and enhance the efficiency in a diverse number of applications. Over the past decade, many studies have been published on the fabrication of nanofibers and their applications in various fields. In this review, novel biological, chemical, and electrical characteristics of nanofibers as well as their recent status and achievements in medicine, chemistry, and electronics are analyzed. It is found that nanofibers can induce fast regeneration of many tissues/organs in medical applications and improve the efficiency of many chemical and electronics applications.

Designing electrospun nanocomposite poly(vinylidene fluoride) mats with tunable wettability

“…It was observed that the maximum WCA is associated with a beads-only morphology and small amount of pearlson-string, where the minimum WCA was observed on an electro-spun mat with a large beaded-free fibrous morphology. PVDF is inherently hydrophobic as it has low surface energy [15,16]. The enhanced hydrophobicity/superhydrophobicity of the mats is mainly caused by the multiscale (hierarchical) roughness of the surface, which was induced by the micro-/nano-sized fibers or beads and the nanoparticles incorporated in the polymer solution [15,34].…”

“…Due to these intrinsic properties of PVDF, along with the advantages offered by the electrospun fibrous structures such as the high surface area and the flexibility in surface functionalities [16], electrospun PVDF mats have been applied in a wide range of applications [3], either as PVDF alone or with the incorporation of nano-sized fillers [17][18][19][20][21][22][23][24]. Wound healing patches [17], energy harvesting devices [18], electrolyte for lithium-ion batteries [19,20], and superhydrophobic surfaces for different purposes [3,21] are a few examples.…”

Aktivitas Antijamur, Antibakteri Dan Penyembuhan Luka Ekstrak Resin Jernang

“…Serat nano mempunyai sifat unik dan berpotensi untuk diaplikasikan di bidang biologi, kimia, elektronik, teknik, biomedis, dan pelindung berbagai produk (Subiah, Bath, Tock, Pameswaran, & Ramkumar, 2005;Wei et al 2010;Kimura , , Kim, Lee, & Kim, 2010). Salah satu aplikasi serat nano dalam bidang medis adalah untuk meningkatkan efisiensi pemakaian obat (Subiah et al 2005; ., Nguyen et al 2012). Salah satu aplikasi serat nano ., dalam b idan g bio medis adalah unt uk menyembuhkan luka dengan memasukkan bahan antibiotik pada matriks serat nano (Soscia, Raof, Xie, Cady, & Gadre, 2010).…”

“…Sedangkan ekstrak dengan pelarut etil asetat dan metanol tidak ada aktivitas jamur sama sekali (zona hambat 0 mm) sehingga ekstrak tersebut resisten terhadap jamur khususnya C. albicans A. flavus. dan (Subiah et al, 2005;Nguyen et al, 2012). Matriks serat nano yang digunakan untuk media ekstrak jernang sebagai penyembuh luka seperti pada Gambar 3A dan 3B.…”

Keratinous Materials as Novel Absorbent Systems for Toxic Pollutants

“…To improve the absorption and detoxification of warfare agents, the systems should possess a high surface area with highly interacting chemical functionalities that can detoxify the agents via converting them into non-toxic products. Systems containing charcoal impregnated with metal or metal oxides are currently being used for protection against chemical and biological aerosols and vapours [87][88][89] . lightweight and portable products such as textile face masks or protective clothing would be ideal for such applications.…”
