Nanoparticles have a high surface area to volume ratio and can release ions into solution. Understanding the mass fraction of ionic to solid colloidal material can be critical in assessing the stability and performance of nanoparticles in various applications. Our diverse sample preparation and measurement capabilities enable us to analyze many sample types that extend beyond the realm of colloidal chemistry.

To measure concentration, samples are prepared appropriately and measured on a Thermo X-Series II Quadrupole Inductively Coupled Plasma Mass Spectrometer (ICP-MS).

UV-Visible spectroscopy (UV-Vis) measures the extinction (scatter + absorption) of light passing through a sample. Nanoparticles have unique optical properties that aresensitive to the size, shape, concentration, agglomeration state, and refractive index near the nanoparticle surface, which makes UV-Vis a valuable tool for identifying, characterizing, and studying nanomaterials.

At nanoComposix, spectral analysis is performed with an Agilent 8453 single beam diode array spectrometer which collects spectra from 200-1100 nm using a slit width of 1 nm. Deuterium and tungsten lamps are used to provide illumination across the ultraviolet, visible, and near-infrared electromagnetic spectrum. Spectra can be collected from samples as small as 60 µL using a microcell with a path length of 1 cm.

NanoComposix is a world leader in nanomaterial research and development, manufacturing, and processing. Since 2004, we have developed innovative solutions to meet the specific product requirements of our customers in fields ranging from material manufacturing to medical diagnostics. Project scale ranges from custom fabrication requests to collaborative development projects where we solve R&D and scale-up challenges for the commercial launch of nano-enabled products.

At nanoComposix we have completed over a thousand custom projects ranging from self-healing aerospace composites to targeted cancer drug delivery. In almost every case we’ve been most successful when we have brought the customer’s end metric in-house. By understanding and having the analytical measurements necessary to determine if both the nanoparticle fabrication and integration are successful, we can rapidly iterate the nanoparticle chemistry and processing to achieve your goal. Below are just a few examples of our areas of expertise – please contact us to find out more about our capabilities and expertise.

NanoComposix produces GMP/ISO13485 compliant nanoparticles for medical devices, topical therapeutics and combination products (drug/device) for Phase I and Phase II clinical trials. In collaboration with our San Diego based partners, we can provide a complete solution of particle fabrication, formulation and sterile fill. Whether you are looking for materials for proof of concept clinical trials or scaling towards production we will work with you to develop a process that is both cost-effective and compliant.

One of the challenges of GMP nanoparticle production is defining the appropriate level of controls and processes that are necessary in order to manage risk. For each customer, we collaboratively work through a multi-stage process to define a GMP transition plan that is appropriate for the target application. At the end of each stage a design review meeting is conducted to review work completed and to plan the next stage.

NanoComposix has a multi-disciplinary team of scientists with backgrounds in chemistry, physics, engineering and earth sciences. We have worked with over a hundred different clients to develop materials, composites and formulations with tailored optical and physical properties for a wide range of applications including medical devices, nanoparticle drug delivery, optical sensors, and consumer products. No two applications or experiments are the same – we can modify our standard products or develop new materials to meet your needs. Read below for more information or contact us to begin discussing how we can develop a nanomaterial for your needs.

NanoComposix Customization Capabilities

COMPOSITION

Our scientists have experience synthesizing a wide variety of metals, oxides, semiconductors and polymeric nanomaterials. We can assist with process optimization, scale-up, and ISO/cGMP compliant manufacturing of an existing protocol, or develop new chemistry to create your desired material.

SIZE

We stock a wide range of particle sizes, and can fabricate additional sizes on demand. Many of our metal nanoparticles can be fabricated with nanometer control over dimensions up to 200 nm. Polymeric, metal oxide particles and core/shell constructs can be produced with sizes up to 1 µm.

SURFACE

Our standard gold and silver nanoparticles have a variety of different anionic and cationic capping ligands available. In addition, we can fabricate nanomaterials with specific functional groups, polymers, biomolecules, and inorganic coatings. Precisely controlled silica coatings can be applied to the majority of our particles.

CONCENTRATION

Need solutions with a high optical density, or concentrated as an additive for composites? We have developed techniques for processing and stabilizing particles at high concentrations. We use UV-visible spectroscopy and ICP-mass spectroscopy to accurately measure material concentration and extinction coefficients.

OPTICAL PROPERTIES

We can tune the absorbance and scattering of materials throughout the visible and infrared spectrum by changing the morphology and composition of the nanomaterials (see our Knowledge Base article on Color Engineering for examples). Additionally, we can incorporate fluorophores for light emission at desired wavelengths or attach reporter molecules to give strong Raman signals.

THIN FILMS AND COMPOSITES

Our control over surface chemistry and particle stabilization allows us to incorporate materials into different water-based or organic resins to form well-dispersed composite materials. We also use a variety of custom-designed equipment for spraying and depositing nanomaterials as uniform thin films onto large substrates and attaching nanoparticles to textile fibers.
