The Three Most Critical Insights in Regenerative Medicine

ROKIT Healthcare INVIVO .jpgINSIGHT #1) Traumatic injuries, vascular abnormalities, cancer treatment and malfunctioning organs…traditionally, these involve loss of tissue or organ that could be restored only through surgical transfer from the patient and donor or through the use of synthetic materials. However, common challenges facing surgical care are that there is only so much tissue that can be removed from the same patient to reconstruct a damaged area. Also, the use of human or animal donor tissues have posed inherent risks of infection and graft failure.



ROKIT Healthcare INVIVO_1.jpg


INSIGHT 2) But perhaps one of healthcare’s most profound problems, especially in the face of a globally aging population, is the sheer shortage of organ donors and rejection in existing transplantation methods. In 2016 in the U.S., around 116,000 were on the waitlist for an organ transplant while less than 10% of that number made up the donors list. Similar figures (respective to population size) are reported from other developed countries as in the EU; in less developed countries, the numbers on the waiting list are grossly masked by the numbers of people who pass away without even making it to the waitlist.

It is true that over the years post-transplantation 5-year survival rates have significantly improved (73% today versus 63% in 1980s for the heart) thanks to advances in immunosuppressive drug development. However, patients subjected to chronic regimens face new risks. From the risks of developing non-adherance to risks of developing antibodies to the biologics, post-allogeneic transplant management has its own concerns that can decrease quality of life and increase healthcare costs.

INSIGHT 3) There has been a rapidly growing attention to 3D printing in biomedicine in the past 5 years, both as a tool for tissue engineering research but also for clinical applications taking advantage of the unique benefits of personalized, automated printing of cells and biomaterials. The movement of the 3D bioprinting community is toward one vision – to generate organs and tissues on demand according to patients’ needs, using patients’ own cells.

In just a little over a decade since it was introduced to medical application, 3D printing has demonstrated its ability to revolutionize the delivery of health care across the world. Beyond the use in surgical prototyping and planning, 3D printing is being applied in fabricating constructs (medical devices or implants) with required structural, mechanical, and biological complexity that conventional methods lack in reproducing for patients. A 3D-printed bioresorbable airway splint saved a newborn’s life in the U.S.; a patient suffering with a degenerative cervical spine received a 3D-printed spinal implant recapitulating the complex internal architecture; a production of skin grafts clinically proven to treat burns was automatized with a 3D printer in Spain.

Sensofar Metrology

Sensofar Metrology

Sensofar Metrology is one of two divisions of the Sensofar group, based in Barcelona, Spain, an innovation and technology hub. Sensofar Metrology is renowned for its:

  • High-end, non-contact, 3D surface profilers based on complementary confocal, interferometry, focus variation and spectroscopy reflectometer techniques;
  • Consultancy within the field of metrology;
  • Advanced R&D generating patented technologies contributing to hundreds of surface metrology applications worldwide.

Non-contact 3D surface metrology

3D surface metrology is the measurement and characterization of micro- and nano-scale features on natural or manufactured surfaces. This is done efficiently by capturing the 3D spatial coordinates of points on a surface using a non-destructive optical technique.


 Surface topography at the nanometer level

Optical surface profilers have crucial advantages over tactile approaches:

  • Measurement is non-contact, so there’s no damage to the object being measured;
  • Optical techniques can measure through transparent media, are fast and flexible, and yield 3D (areal) results;
  • Measurement performance depends on wavelength and numerical aperture, eliminating limitations caused by the physical size of a stylus tip.

The most common optical techniques available are confocal, interferometry and focus variation, each of these has their own strengths and weaknesses.

Sensofar Metrology_2.png

Superior vertical resolution with confocal

Confocal: Confocal profilers measure the surface height of smooth to very rough surfaces, with spatial sampling as low as 0.10 μm—ideal for critical dimension measurements. High NA (0.95) and high magnification (150X) objectives are available to measure steep local slopes >70° on smooth surfaces with and up to 86° on rough surfaces. Sensofar’s proprietary confocal algorithms provide vertical repeatability on the nm scale.

Interferometry: White-light vertical scanning interferometers (VSI) measure the surface height of smooth to moderately rough surfaces, providing nm vertical resolution regardless of the NA. Sensofar’s new S neox optical 3D profiling microscope can use all available magnifications to profile shape features with no compromise in height resolution.

Focus variation: Focus variation has been developed for measuring the shape of large rough surfaces. Sensofar’s implementation of this approach has been specifically designed to complement confocal measurements at low magnification. Highlights of the technology include high slope surfaces (up to 86°), highest measurement speeds (mm/s) and large vertical range. This combination of features is largely suited to tooling applications.


Sensofar Metrology products

New S neox: The new S neox optical 3D profiling microscope outperforms all previous microscopes of its kind in terms of performance, functionality, efficiency and design. It combines all three of the above techniques: confocal (best for surfaces with high slopes), interferometry (highest vertical resolution) and focus variation (measures shape in seconds). The S neox does all this in the same sensor head without any moving parts. The S neox delivers three-in-one technologies for class-leading areal measurement.

Sensofar Metrology_4.png

S neox helps in archaeological study of an ancient rock drawing

S neox Five Axis: The S neox Five Axis S measures samples at different positions of rotation and elevation,thereby generating a group of individual measurements. The SensoFIVE software merges all of the surfaces, providing a sample surface with high accuracy by using the stacked image information of each single surface measurement. Merging different elevations, the system can provide shape and form information on sharp edges and/or critical surfaces.

DLS at High Concentration

Dynamic Light Scattering (DLS) is an effective measurement technique used for measuring the hydrodynamic size of common nanomaterials including colloids, nanoparticles, proteins, and polymers. Despite the versatility of this technique, there are several important considerations that cannot be ignored when using light scattering to characterize high-concentration solutions. While it is possible to make measurements on high volume-fraction samples without dilution, it raises additional questions about the meaning of the hydrodynamic size. To understand why this is the case we need to discuss two effects encountered in concentrated solutions: multiple scattering and mutual diffusion.

Compounding solutions for 3D filament production

Optimize formulation and production in fewer steps

With the popularity of 3D printing new polymer formulations need to be tested in order to meet the demands of new product applications for industries such as aerospace, medical devices, and automotive. Consequently, polymer compounding for the production of novel 3D filaments becomes a critical step in the workflow for designing successful 3D printing applications.

Advantages of twin-screw extrusion for fused filament fabrication (FFF)

The Thermo Scientific™ Process 11 Twin-screw Extruder and the Thermo Scientific™ HAAKE™ PolyLab OS Rheomex PTW Twin-screw Extruder offer significant benefits over single-screw extruders for 3D filament development to help:

  • Minimize or eliminate the effects of coalescence to maintain particle size distribution
  • Avoid a second heat history when processing heat sensitive polymers
  • Improve layer-to-layer adhesion with uniform binder dispersion
  • Avoid time and energy consumption by eliminating the need to dry hygroscopic materials
  • Reduce waste of expensive additives like pharma excipients, graphene and metals

Thermo Scientific™ Process 11 Lab-scale 3D Filament Production System Process 11 Lab-scale

Use this compact benchtop solution for research-scale formulation and process development. Figure 1 shows this system with:

  • Process 11 Twin-screw Extruder
  • Thermo Scientific™ Process 11 Melt Pump
  • Filament spooler

From 20 g/h up to 2 kg/h throughput, this system is ideal for development of new compounding processes. Easy to operate this system provides process data that supports the scaling up of your 3D filament production process, while reducing the amount of expensive raw material during formulation development

FL53142-3D Filament Systems Promo-EN-FL-53142-FINAL



Reduce 3D filament development time

Streamline 3D filament development by combining compounding and filament formation in one system. Based on our twin-screw extruders, we have designed two systems that allow you to quickly test different formulations and produce spooled 3D filaments in fewer steps than traditional workflows. Both systems produce filaments directly from the compounding process by using a melt pump for pulsation-free output, which ensures a precise filament diameter and significantly reduces time and labor costs. The thermal stress on the filament material is also reduced by eliminating unnecessary heat-cool cycles that occur if mixing and filament production are separated.

Thermo Scientiἀc™ HAAKE™ PolyLab Pilot-scale 3D Filament Production System

Use this system for lab-to-small scale process development and production. Figure 2 shows this system with:

  • HAAKE PolyLab OS Rheomex PTW Twin-screw Extruder
  • Thermo Scientiἀc™ Melt Pump for the OS Rheomex Extruder
  • Filament spooler on a mobile bench

Reach material throughputs of up to 5 kg/h with this system that includes the ability to characterize new material compounds with mixer tests and capillary rheology.
