Research on the Development of Fibroin and Nano-Fiber from Silk Cocoons for Regenerated Tissue Engineering Applications by Electro-Spinning

引用

Advances in Nanoparticles 2024年第1期13卷 1-9页

作者： Md Kamrul hasan Xinbo Ding School of Textile Science and Engineering International Silk Institute Zhejiang Sci-Tech University Hangzhou China

In this paper, the main goal is to prepare silk fibroin nano-fiber, which is used for regenerated tissue applications. Silk scaffold nano-fibers made by electro-spinning technology can be used in regenerated tissue applications. The purpose of the research is to prepare a silk-fibroin nano-fiber solution for potential applications in tissue engineering. Using a degumming process, pure silk fibroin protein is extracted from silk cocoons. The protein solution for fibroin is purified, and the protein content is determined. The precise chemical composition, exact temperature, time, voltage, distance, ratio, and humidity all have a huge impact on degumming, solubility, and electro-spinning nano-fibers. The SEM investigates the morphology of silk fibroin nano-fibres at different magnifications. It also reveals the surface condition, fiber orientation, and fiber thickness of the silk fibroin nano-fiber. The results show that regenerated silk fibroin and nano-fiber can be used in silk fibroin scaffolds for various tissue engineering applications.

Preparation and Performance Study of PVA-Based Flexible Sensors

引用

Open Journal of Polymer Chemistry 2024年第1期14卷 19-40页

作者： Md Kamrul hasan Xinbo Ding School of Textile Science and Engineering International Silk Institute Zhejiang Sci-Tech University Hangzhou China

Flexible sensors have great potential for monitoring human body motion signals. This paper presents a flexible sensor that uses zinc oxide (ZnO) to improve the mechanical properties and electrical conductivity of PVA hydrogel. The composite hydrogel has excellent conductive properties and high strain sensitivity, making it suitable for motion monitoring. The PVA/ZnO conductive hydrogel is tested on various body parts, showing effective feedback on movement changes and good electrical signal output effects for different motion degrees, confirming its feasibility in flexible sensors. The sensor exhibits good mechanical properties, electrical conductivity, and tensile strain sensing performance, making it a promising sensor material. It can accurately monitor wrist bending, finger deformation, bending, and large-scale joint movements due to its wide monitoring range and recoverable strain. The results show that the PVA/ZnO conductive hydrogel can provide effective feedback in flexible sensors, which is suitable for use in motion monitoring.

Anorectal malformation(ARM)is a frequently occurring surgical condition in neonates,with a prevalence of 1 in 4000 live births.'In boys with this anomaly,the rectum and urinary tract share a common wall for some distance,often ending up in fistulous *** goals of definite reconstruction are to separate the rectum from the urinary tract without injuring the urethra and mobilizing the rectum to the perineum within the muscle *** the rectum and the urinary tract is the most critical part of this operation and is associated with a significant risk of urinary tract injury.2-5 The original procedure described by Pena and Devries involves multiple stay sutures on the rectal mucosa just above the fistula,lifting the mucosa and continuing a submucosal dissection up to the prostate,where the entire thickness of the intestine can be separated from the urinary tract.
