Precision Microsphere Applications and Benefits:

Categories	Applications	Unique Benefits
Testing Particles for Instrument Design and Testing of Diagnostic Devices	Density Marker Beads PIV - Flow Visualization Seed Media Filtration Systems Container Cleaning Flow Tracing Centrifugation Sedimentation Pharmaceutical Processes Contamination Control Calibration of Microscopes	Clearly Visible Tightly Defined Particle Size Range High Sphericity Custom Color Custom Density Fluorescent Response Specific Index of Refraction Reusable Dual-functionalities has many applications in diagnostic and medical devices, microrheology, and immunoassays. Dual-functional particles can be magnetically or electrically aligned to show a visual response to the stimuli and assist self-assembly of particles in a solution.
Spacer Particles	Adhesives Coatings Electronics Automotive Medical Devices Biotechnology	Controlled Gap Precise Dimensions Diameter Range < 3micron Incompressible Particles
Microspheres for Process Development	Pharmaceutical Technology Industrial Processes Process Scale-up Process Troubleshooting Process Control	Microspheres are used instead of the expensive drug or process component to develop and troubleshoot the process by replicating size, color and density of the target particles. Fluorescent particles can be used as a visual marker.
Medical Spheres	Cosmetic Surgery Cosmetic Fillers Reconstructive Surgery Urology Porous Ceramics Dentistry Medical Testing Medical Research Drug Delivery	Controlled particle size and spherical shape efficiently fills wrinkles and gaps. Cospheric microspheres have the tight particle size and sphericity to meet drug delivery requirements. In addition, our spheres can be loaded upto 40% by weight with added ingredients. They can be custom made with magnetic or electric functionality and as many coating layers as necessary to enable external delivery of microspheres to the desired organ.
Retroreflective Spheres	Decorative and Safety Inks Road Lining and Rail Paints Retroreflective Coatings High Visibility Materials Bright Color Materials	Create a range of optical effects Maximize light transmission Enhance retroreflectivity Combine with pigments and dyes to enhance the color Substitute for expensive pigments to maintain the color at a fraction of the cost.
Fluorescent Spheres	Highly Visible Testing Particles PIV - Flow Visualization Flow Process Development Process Troubleshooting Pharmaceutical Processes Contamination Control Calibration of Microscopes Testing Medical Devices	Highly visible marker particle Controlled particle size Controlled sphericity Emission wavelength spectra Color-changing particles
Metal-Coated Spheres	Additives in paints, adhesives, composites EMI shielding Electronics Conductive epoxy and bondline	Highly conductive particles Optimized for EMI shielding Efficient conductive filler than materials such as nickel and graphite powders and flakes. By incorporating silver coated microspheres into their products, manufacturers can realize significant weight savings over solid silver particles and other conductive fillers.
Neutrally-Buoyant Spheres	Flow visualization Medical device validation Simulation of flow of small particles (fish eggs, algae, small creatures)	Bright fluorescent microspheres are supplied in dry powder form and specifically designed with density ~1g/cc for suspension in fresh water, enabling flow visualization and analysis of fluid flow in a device. Controlled particle size ranges enable investigation of maximum particle size passing through the openings, filters and membranes. Particles exhibit a strong fluorescent response and are color stable in solution.
Paramagnetic Particles	Physics Biomedical Technology Microscopy Analytical Techniques Solid Phase Immunoassays Bacteria Detection High Throughput screening Rapid Tests Cell Sorting Biosensors Nucleic Acids Technology Microfluidics	Paramagnetic microspheres have the ability to increase in magnetization with an applied magnetic field and loose their magnetism when the field is removed. No residual magnetization is observed and that provides the end use very practical advantages, including ease of separation and suitability for automation.
Phosphorescent Particles	Process Diagnostics Blind Tests Delayed long response particles	Phosphorescent microspheres are used for process study and blind tests especially in medical technology industry, diagnostics, troubleshooting, process flow, medical research and other industries. Particles exhibit a strong long-afterglow phosphorescent response and are stable in solution.
