Creating Tubular Nanofibers with NANON

Nanofiber technology holds great promise for a wide range of applications.In this post, we introduce tubular nanofibers—a unique structure that can be created using our electrospinning device, NANON. What Are Tubular Nanofibers? At our company, we produce straw-like tubular nanofibers by rotating mandrel rods with diameters ranging from 2 mm to 10 mm while spraying a solution jet onto them. These fibers are expected to be applied in a variety of fields, such as medical uses like artificial blood vessels and energy devices. In particular, when using biocompatible polymers, applications in cutting-edge medical fields—such as tissue engineering and drug delivery systems—are expanding. Fabrication of Tubular Nanofibers Using NANON In this demonstration, we created tubular nanofibers using the following setup: Features of Our Tubular Nanofibers ・Uniform Structure The high-speed rotating mandrel collector enables the formation of smooth and consistent nanofibers. ・High Versatility Applicable to a wide range of uses, including filters, biomedical applications, and energy devices. ・Flexible Design The diameter and thickness of the fibers can be controlled by adjusting the size and rotation speed of the collector. Future Outlook As we further advance our tubular nanofiber fabrication technology, we aim to develop materials with even more sophisticated functions. In particular, we anticipate expanded use in the medical field, such as artificial blood vessels and drug delivery systems. Our company continues to enhance our electrospinning technology, striving to provide equipment capable of producing various types of nanofibers.

【Paper】A Macrolide-loaded Nanofiber Insert for Sustainable Intraocular Administration Based on Polycaprolactone and Cellulose Acetate: A Pharmacokinetic Study in the Rabbit Eye

➡please click here for the paperA Macrolide-loaded Nanofiber Insert for Sustainable Intraocular Administration Based on Polycaprolactone and Cellulose Acetate: A Pharmacokinetic Study in the Rabbit Eye Bioavailability and DDS Azithromycin (AZM) is a broad-spectrum antibiotic that has anti-inflammatory properties and is used as an ophthalmic agent to treat ocular infections because it acts to cause bacterial conjunctivitis. However, eyedrops have limited bioavailability and require frequent administration. Therefore, in recent years, nano-based novel drug delivery systems that can increase corneal permeation and enhance drug residence lengthening and drug delivery have attracted attention. Bioavailability: an indicator of how well a given drug (formulation) reaches and acts in the systemic circulation. Effectiveness and Prospect of Eye Points by DDS Using Nanofibers Among these methods, the use of nanofibers has characteristics such as high surface area, porous structure, and high drug loading capacity, making it possible to insert nanofibers directly into the conjunctive sac to extend drug residence time at the surface of the conjunctive membrane, and reducing the number of drug dosing, making it one of the most suitable methods for eye-sustaining drug delivery. In practice, a large number of polymers are processed into nanofibers using the electrospinning method. We used cellulose acetate (CA), which is non-toxic, biodegradable, and biocompatible, and polycaprolactone (PCL), a hydrophobic polymer that has received FDA approval for drug delivery, to fabricate nanofibers loaded with AZM and evaluated their efficacy. Since they used to fabricate AZM loaded nanofibers with hydrophilic polymers, they have also evaluated improvements in their pharmaceutical≫ more

Localized cancer photodynamic therapy approach based on core–shell electrospun nanofibers

My name is Tsumugi, and I am a researcher.In this issue, we investigated a localized cancer photodynamic therapy approach based on core-shell electrospun nanofibers! TsumugiShe is a second-year researcher in the Nanofiber Division of MECC.Her hobbies include reading science magazines and the latestresearch papers, as well as karate. Her special skill is speaking Chinese. <Background and Purpose>The fourth largest number of cervical cancers among women. Treatment includes surgery, radiation therapy, and chemotherapy, but side effects are common and efficacy is limited. Therefore, alternative treatments such as photodynamic therapy (PDT) are being considered to minimize side effects and prevent recurrence. PDT is a treatment method based on the principle that various biomolecules are oxidized and the target tissue is irreversibly destroyed by generated singlet oxygen. Photoactive molecules called photosensitizers (PS) are absorbed in the cancerous cells, and PS is activated by irradiating the target site with a specified wavelength. Porphyrins (Por) and their derivatives are commonly used in PS. While Por has advantages such as high singlet oxygen-quantum yield, minimal dark toxicity, and rapid removal from the body, it also has several drawbacks, such as a large amount of dose required for full-body administration to achieve a stable effectiveness, leading to prolonged light sensitivity, and the possibility of compound elimination by targeting the localized area of the tumour. We intend to incorporate PS into the Local Drug Delivery Systems (DDS) to solve these shortcomings. Implantation of a local DDS at or near the tumour site allows direct delivery of PS to≫ more

Hyaluronic Acid Induction Promotes the Differentiation of HumanNeural Crest-like Cells into Periodontal Ligament Stem-like Cells

Dr. Jun Tomoshikiyo et al. of Graduate School of Dentistry, Hokkaido University presented Hyaluronic Acid Induction Promotes the Differentiation of HumanNeural Crest-like Cells into Periodontal Ligament Stem-like Cells Our NANON was used in the paper “Hyaluronic Acid Induction Promotes the Differentiation of HumanNeural Crest-like Cells into Periodontal Ligament Stem-like Cells! The following is a summary of the paper. When the PDL is damaged beyond repair, periodontitis can progress and teeth can be lost. Periodontal tissue contains periodontal tissue stem cells (PDLSCs) that have the ability to regenerate periodontal tissue, but the population of PDLSCs in periodontal tissue is thought to be very small, limiting the transplantation of autologous PDLSCs. Neural crest (NC) cells can differentiate into a variety of cells and tissues, and some NC cells can remain in cranial NCs to give rise to PDLSCs. This suggests that differentiation of NC cells into PDLSCs in periodontal tissues may promote periodontal tissue regeneration. However, the difficulty in obtaining large numbers of NC cells is the main factor limiting the application of NC cells in regeneration research. Therefore, we focused on SK-N-SH cells, a neuroblastoma cell line, as a method to culture periodontal tissue stem cells for periodontal tissue regeneration, and developed a new scaffold for cell culture. I want to take good care of my teeth because I don’t want them to disappear, but it is also difficult to take care of them.If there is a way to regenerate them, it would be very helpful! First, PDL tissue was detached≫ more
