Porous Glass Microspheres
A tailored, single-stage and scalable manufacturing process
In brief
Porous glass microspheres (MS) are produced via a novel flame spheroidisation process, enabling precise tailoring of MS porosity, size, chemistry and other variables to address a wide range of potential applications.
Compared to other manufacturing techniques, this single-stage process is: efficient, less time-consuming and energy intensive, scalable, and offers better control over pore size, interconnected porosity and morphology.

Background
Microspheres exhibit greater advantages over irregular-shaped particles, with an improvement in flow properties and the porous or hollow structure. Porous microspheres can be loaded with active or functional entities. They have a relatively large surface area and allow for the encapsulation of components, leading to a wide range of uses, from adhesive additives to drug delivery or energy storage.
Key features
This technology is a novel flame spheroidisation process to manufacture highly porous glass microspheres.
Key features are:
Research has proven the effectiveness of injectable pastes of porous calcium phosphate glass microspheres in tissue engineering and bone regeneration. Glass microsphere formulations with 40 mg/mL xanthan gum displayed optimal flow characteristics and were readily injectable via a syringe-needle system (3–20 mL, 18G and 14G needles), proving their potential as a cell (or other biologics) delivery vehicle.
Tailorable properties
Applications in engineering, biotechnology and healthcare
Applications for this novel fabrication process have been identified in: medical devices, bone regeneration, resorbable implants, separation science, osteoplasty, bone surgery, joint surgery, hip revisions, spine surgery, spinal fusion, osteo-conductivity, orthopaedic surgery, dentistry, bone fixation, filtration and fillers.
We are interested in licensing or collaborations related to potential areas of application. Small samples for assessment can be supplied by agreement.
