Application of Fluorescent Label in Polymer Nanofibers

Abstract

The electrospinning of fluorescent probe polyamide 6 doped by 7H-benzimidazo[2,1-a]benzo [de]isoquinolin-7-on is presented as a model processing photoluminescent nanofibers. The presence of the fluorescent probe in the fiber layers was confirmed by attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR); the surface nanofiber structure was described by high-resolution fluorescence microscope and scanning electron microscope images. The prepared nanofibers with the fluorescent label were further characterized by fluorescence spectroscopy, both in the solid phase and in the solution.

Fluorescent polymer nanofibers based on polycaprolactone and dansyl derivatives for development of latent fingerprints

“…20,22,47,48 PCL is able to interact with the dansyl fluorophores through the formation of hydrogen bonding between the carbonyl group of PCL and the amine or carboxylic acid groups of DnsCad or DnsGly. 49,50 The maximum emission wavelength of the electrospun PCL/fluorophore is hypsochromically shifted compared with the fluorescence maximum of pristine fluorophores, suggesting that such blue-shift is due to the immobilization of the fluorophore within the PCL matrix, as observed by Mocanu et al 51 for the dansyl fluorophore immobilized in alginate and/or cyclodextrin and Zarybnicka et al 52 by applying fluorescent label in polymer nanofibers. The hypsochromic shift was more pronounced for electrospun PCL/DnsGly mats (107 nm) when compared with the PCL/DnsCad (16 nm), since the interaction C O H O from DnsGly is stronger than C O H N from DnsCad.…”

Challenges and Potential Solutions for 100% Recycling of Medical Textiles

“…Genetic mapping offers an important method at the molecular level to understand the genetic architecture of quantitative traits (Zins and Howard 2011 ). Thousands of QTLs responsible for lint yield, yield elements, fiber quality and other traits have been mapped and characterized using G with the construction of high density genetic maps of tetraploid cotton, respective standards-the-G. Inter-specific populations of F2, BC and RIL in Barbadense (Zarybnicka et al 2017 ).In the textile industry, fiber is a fundamental raw material.). In this analysis, the QTLs detected provide new knowledge to improve the quality of fiber and especially useful for marker-assisted selection (Zhiyuan et al 2014 ).…”

Elektro çekim yöntemiyle Çinko Borat katkılı P(AN-VAc) nanolif tekstil yüzeylerinin üretimi ve termal karakterizasyonu

“…Son yıllarda, nanolif esaslı materyaller yüksek yüzey alanı/hacim oranı, çok küçük gözenek boyutu, esnek yüzey fonksiyonelliği, mekanik özellikleri vb. üstün özellikleri sebebiyle doku mühendisliği [25][26][27], koruyucu malzemeler [28][29][30], filtrasyon [31][32][33], biyomedikal uygulamalar [34][35][36], kompozitler [37][38][39] ve çevre mühendisliği [40] gibi birçok uygulama alanlarında ve AR-GE çalışmalarında görmekte olduğu rağbeti sürekli olarak artırmaktadır [41][42][43]. Nanolif üretimi için en uygun ve etkin yöntemlerden biri olan elektro çekim yöntemi yüksek voltaj uygulanan eriyik veya çözelti halindeki polimerin, elektrik alanın etkisiyle nano çapta liflere ayrışması ve toplayıcı üzerinde bir ağ şeklinde bir araya gelmesidir [44][45][46].…”
