Biodegradable poly(ethylene oxide) nanofibers containing silver nanoparticles were successfully prepared by the electrospinning without the further reduction process which could cause the damages of nanofibers. Transmission electron microscopy showed that the silver nanoparticles were dispersed in poly(ethylene oxide) nanofibers without aggregation. This facile process would be the effective method to prepare the silver nanoparticles/polymer nanocomposites. Moreover, the silver nanoparticles embedded in the poly(ethylene oxide) nanofibers were responsible for the antibacterial activities against Staphylococcus aureus and Klebsiella pneumoniae, respectively. Therefore, it is expected that the silver nanoparticles/poly(ethylene oxide) nanocomposites can be used for practical applications as the biomaterial.

This paper presents a novel atomizing methodology along the single strand of an optical fiber integrated with single-walled carbon nanotubes. Based on this photonic device, numerous droplets generation with zeptoliter volume scale was confirmed.

We incorporated silver nanoparticles into a nylon solution, fabricated electrospun nanofibers, and studied various parameters of the electrospun fibers. We found that the addition of silver nanoparticles introduces antibacterial effects into nylon composite fibers. The average fiber diameter and fiber morphology was greatly affected when parameters such as solution concentration and the amount of silver nanoparticles were changed. The composite fibers that we prepared have the potential to be used as filtration membranes.

For the first time, poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) nanofibrous membrane has been fabricated via electrospinning method. To improve the electrospinnability and reduce the diameter of fibers, the solvent and salt additives were used that affected on the parameters including such as the viscosity and the conductivity of the electrospinning solution for poly(3-hydroxybutyrate-co-3-hydroxyhexanoate). Since the additional salts should be removed, it could be inferred that the co-solvent system was predominant to prepare the nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) membrane. This biodegradable nanofibrous poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) membrane has a great potential to be used in the various application fields such as tissue engineering, implants, packaging materials, agriculture, and so on.

We present a fiber-optic sensor based on the principles of a Fabry–Perot interferometer (FPI), which promptly, sensitively, and precisely detects blood clot formation. This sensor has two types of sensor tips; the first was crafted by splicing a tapered fiber into a single-mode fiber (SMF), where fine-tuning was achieved by adjusting the tapered diameter and length. The second type is an ultra-compact blood FPI situated on the core of a single-mode fiber. The sensor performance was evaluated via clot-formation-indicating spectrum shifts induced by the varied quantities of a thrombin reagent introduced into the blood. The most remarkable spectral sensitivity of the micro-tip fiber type was approximately 7 nm/μL, with a power sensitivity of 4.1 dB/μL, obtained with a taper fiber diameter and length of 55 and 300 μm, respectively. For the SMF type, spectral sensitivity was observed to be 8.7 nm/μL, with an optical power sensitivity of 0.4 dB/μL. This pioneering fiber-optic thrombosis sensor has the potential for in situ applications, healthcare, medical monitoring, harsh environments, and chemical and biological sensing. The study underscores the scope of optical technology in thrombus detection, establishing a platform for future medical research and application.
