At the 2018 Society for Biomaterials in Atlanta, GA, clinicians, researchers, and students from around the world will convene to discuss their latest research, form new collaborations, and be inspired by the work of their peers.  This interdisciplinary gathering is a critical pathway to identifying issues with current technologies, and for translating academic research towards clinical practice. Luna’s Health Science Grouphas been presenting annually at the Society for Biomaterials Meeting since 2012, and is excited to continue this trend with updates on three different technologies at the 2018 meeting. Join us in Atlanta as we discuss our sprayable barrier for the prevention of postoperative adhesions, our BIOcular™ products designed for the regeneration of corneal tissue, and our line of TuneCoat™ advanced wound dressings for the localized delivery of analgesics. Descriptions of each technology and details for presentation times are provided below.

Development of a Sprayable Biopolymer Hydrogel for the Prevention of Postoperative Adhesions – Podium Presentation – Thursday April 12, 2018; 2:45 – 3:00 pm

Luna has developed a sprayable hydrogel for application over irregularly shaped internal tissues to prevent the formation of postoperative adhesions. The product is colored to enable visualization of application and has been designed for application with pressurized carbon dioxide to form a temporary barrier over healing tissues during the healing process. Luna has demonstrated biocompatibility of the product in in vitro and in vivo models, and has demonstrated functional prevention of postoperative adhesions in multiple preclinical models in different species. Luna is now working to transition the technology towards final preclinical validation and commercialization. Join us on Thursday April 12, 2018 in the session entitled, “From Conception to Clinical Trial: Examples of Technology Development” as we discuss this exciting technology and its transition from the benchtop through in vivo validation. 

Delivery of Stem Cells using Biomimetic Materials Designed for Ocular Surface Repair – Podium Presentation – Saturday April 14, 2018; 12:00 – 12:15 pm

Luna is developing multiple unique materials solutions for ocular surface repair and globe stabilization. These nanofiber-reinforced hydrogel bandages are capable of mimicking the natural structure of the corneal surface to encourage wound healing responses following difficult to heal corneal injuries and are designed for sutureless application to the corneal surface using photochemical tissue bonding techniques. Luna is investigating the effects of various chemistries on the resultant mechanical, optical, and biological properties of the dressings, and has recently demonstrated the ability to use these dressings to deliver human adipose-derived stem cells to the corneal surface to further improve corneal regeneration. Join us on Saturday April 14, 2018 in the session entitled, “Ophthalmic Biomaterials SIG” to hear more about these unique new material solutions for corneal surface repair. 

Nanofiber-Based Analgesic Bandages for Localized Treatment of Neuropathic Pain  – Poster Presentation – Multiple Times

Finally, Luna is developing unique nanofiber bandages for transdermal delivery of nerve-targeting agents to peripheral nerves. The technology utilizes Luna’s experience developing nanofiber-based dressings that can be loaded with therapeutics to achieve controlled, extended release to the wound site. Luna has demonstrated preliminary feasibility of this technology to load and release the therapeutic from these complex nanofiber-based structures, and has demonstrated subsequent targeting of the delivered product preferentially to nerve cells. Join us at either of the poster sessions to learn more about these novel drug-loaded bandages:

Poster Session 1 and Exhibit Reception; Thursday, April 12, 2018 from 6:00 PM – 8:00 PM 
Poster Session 2 ; Friday, April 13, 2018  from 3:45 PM – 5:15 PM

Combining very high strength with light weight, composite materials are finding their way into more and more structural and cosmetic parts within the aerospace and automotive industries. As composite use grows throughout these industries, efficient and effective methods of non-visual damage detection are needed. To meet this need, Luna has demonstrated that high spatial resolution (0.65 mm) fiber optic strain sensors incorporated into carbon fiber composite test articles can effectively detect damage from an impact by measuring a change in the strain profile, even when the impact causes fiber fracture and delaminations below the visible surface.

To test this method, a mock aircraft skin panel was fabricated to assess the distance over which the damage imparted to the panel propagates. The panel was fabricated from eight plies of 193 g/m2 3K plain weave fabric with a 19 mm foam core on the mid-plane. Optical fibers were embedded just below the outermost ply in three parallel passes spaced 1 cm apart.

The panel was then impacted to determine the relationship between fiber to impact distance and the strength of the induced fiber signal. A drop style impactor, similar to that which is used in ASTM D7136, was utilized to impart a quantifiable and controlled series of impacts. Strain measurements were achieved using Luna’s ODiSI system for high-definition fiber optic sensing (HD-FOS).

The following figure diagrams the location of 16 impacts. The initial eight impact events were conducted with the same impact parameters. The next six impacts (9-14) were spaced at larger horizontal spacing, and with less energy, to avoid conflating the results of the various impacts. Two final impacts were made at locations 15 and 16 between the bottom two fiber sections, to determine whether especially close proximity between the impact and the fiber altered the response.

The following figure displays strain as a color map on a drawing of the panel after the 4th and 16th impact. Impact site 4 shows successively decreasing levels of strain propagating outwards from the impact location. The yellow circle traces the region of damage based on the reported strain. Note that the center of the circle is almost exactly over the impact location. The lower portion of the figure shows the cumulative damage resulting from all impacts performed on the impact panel. It is obvious that all impact events within ~5 cm of the fibers have resulted in a clearly discernible response in the strain profiles.

While our last post was about our participation in a very focused event concentrating on thin wall packaging, we are now announcing that we will be participating in one of the major plastic industry events.

NPE® is a “must-attend” event for a wide array of people from across the plastics supply chain and the end user market.  Held every other year in Orlando, NPE is produced by the Plastics Industry Association, and draws an average attendance of 65,000, and over 2,000 exhibiting companies.

Thermo_plastics

While we do not have a booth of our own, TeraMetrix (a division of Luna) is proud to announce that their multilayer thickness measurement solution will be presented and/or demonstrated in a number of exhibit booths.  Whether it is a demonstration of online barrier layer measurement at IMDvista (booth S11057), or presentation of an integrated web process control solution at Thermo Fisher Scientific (booth S28161) or Indev-ACT (booth S15131), or measurement of extruded pipe thickness at iNOEX (booth W3191), TeraMetrix T-Gauge® sensors are being used to improve product quality and reduce waste.

The T-Gauge sensor is optimized for the production environment, with a robust, lightweight sensor head suitable for scanning.  The gauge carries UL, CE and FCC certifications, and a Class I Division 1 certified sensor is available for explosive environments.  Its high-speed measurement rate (up to 1000 Hz) and high precision provide unsurpassed performance in online applications.

TGauge_profile

While a demonstration of our T-Gauge capability is always impressive, it is more important to provide a complete solution that can be easily integrated into a manufacturing process.  In conjunction with our partners, we are able to supply just such a solution.

Margaret Murdock (General Manager), as well as John Riccardi (Global Sales), Steve Williamson (Director of Engineering) and Irl Duling (Business Development) will be available during the show to support our integrators, and to develop relationships with new customers. 

John Riccardi comments on NPE, “Eight years ago TeraMetrix introduced the first industrial terahertz platform for real time plant floor deployment.  Since then our channel partners have deployed dozens of T-Gauge systems covering a wide range of plastics applications.   Now TeraMetrix offers disruptive solutions that perform multi-layer measurements previously resolved only with complex arrays of nucleonic or other more costly inefficient technology.”

An important technology for the future of long term space missions is the use of expandable, inflatable space habitats.  Inflatable habitats are key to reducing the weight of space structures, and are not constrained by the size of the launch vehicle.  In order to ensure the reliability of these structures, Luna is working with NASA and the Embry-Riddle Aeronautical University to research and develop a structural health monitoring (SHM) system that can detect and locate damage in an inflatable habitat structure.

 

The flexible materials used in these inflatable structures, including Kevlar woven straps, have been shown to exhibit creep and other forms of degradation over time. Additionally, space structures are subject to impact from high-velocity micrometeoroids and other bits of space debris.  A comprehensive and reliable system is needed to monitor the integrity of the entire inflatable structure.  Researchers from Embry-Riddle Aeronautical University have developed a type of carbon nanotube based ‘buckypaper’ incorporating a layer of piezoresistive strain sensors to cover the outer structure. This will be combined with Luna’s high-definition fiber optic sensing (HD-FOS) integrated into the interior layer of the structure.  Luna sensors were bonded directly to the flexible Kevlar straps that are woven into the structure.

Inflatable_Space_Habitat_Sensing

The first phase of research has demonstrated that the HD-FOS and its ability to monitor surface strain with a resolution of 0.65 mm is very effective for detecting small changes in the state of the structure. HD-FOS, combined with the carbon nanotube sensing material, shows great promise in providing full coverage health monitoring and precise impact detection and assessment.  Luna continues to work with NASA and ERAU to refine the approach and move the system closer to reality.  You can read an overview of the project here, or a summary of the first phase of research here.
