Fabricating stable, monodispersed, and concentrated colloids in aqueous, inorganic, organic, and proprietary substrates. 

TENGENA’s position is enabled by strategic competitive capability in:

  • Customized manufacturing uses cutting-edge, batch-to-batch reproducible techniques with green technology advantages.
  • Nanoplasmonic synthesis across aerosol and liquid interfaces, which eliminates entrainment of unnecessary chemical solvents and ensures flexibility in reducing agents as chemically-free and oxygen-free noble metal processing.
  • Ultra-uniform spherical nanocolloids, ranging from pico- to nanoscale, formed by precisely controlled size (0.1–100 nm) for optimized applications.
  • Scalable one-pot concentrated nanomaterials, exceeding 70 % OD, allowing smooth transitions from prototype development to high-volume production.
  • Extended stability, maintaining structural integrity and functionality up to twelve-months shelf-life period when stored at 4°C and up to six-months shelf-life period when stored at 24°C.
  • Innovative nanocoating solutions using self-assembling and solvent-driven spontaneous pico- and nanoscale architectures, further improving product stability and performance.
  • Cost-effective and time-consuming synthesis with minimal/no purification or defect remediation needed due to the high monodispersed status.

TENGENA SPHERICAL INORGANIC NANOPARTICLES

CHARACTERIZATION

Spherical plasmonic metal nanoparticles distinguish themselves from other nanoplatforms, such as semiconductor quantum dots, and magnetic and polymeric nanoparticles, by unique optical property, such as surface plasmon resonance (SPR), resulting from photon confinement that enhances their both radiative and nonradiative properties. 


Due to the extraordinary efficiency at absorbing and scattering light, spherical nanoparticles are increasingly incorporated into commercial products and technologies, ranging from photovoltaics to biomedical and chemical sensors.


In order to reach industry standards and improve our production capabilities, our inorganic nanoparticles physicochemical characteristics have been analyzed by ultraviolet–visible spectroscopy (UV-Vis), dynamic light scattering (DLS), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS).

Inorganic nanoparticles and nanocolloids have unique and beneficial properties that can be leveraged across a range of product types, including functional coatings, catalysts, additives, conductive inks, antimicrobial, and antitumorogenic. Specifically, the size of inorganic nanomaterials ranges from 1 to 100 nm that are similar to cellular components and microorganisms can be employed as innovative tools in biomedical therapy, diagnostics, and drug delivery. Most inorganic NMs display customizable morphology, high biocompatibility, reliable functionalization, and prolonged circulation in the bloodstream. NMs less than 2 nm size can cross blood brain barrier and cross intracellular membranes. Among lipids, self-assembled proteins, and biopolymers, properly functionalized inorganic particles represent the most promising material in the innovative vaccines development.
