Healthcare/Medical

Nanomaterials can be used in various applications within the healthcare/medical industries.

Applications include bone scaffolds, bio-ceramic implant devices (bones, teeth), antimicrobial applications, coatings for medical devices, biomedical imaging, drug carriers, bio-sensing, water purification and many others.

Copper

Applications:

  • Antimicrobial applications: copper in water treatment (drinking water treatment and transportation), hospital care units, disinfection, working surfaces (i.e. door handles), textiles and other antimicrobial applications

Key selling points:

  • Pure copper, no copper oxide
  • Nanoparticles provide unique bactericidal mechanisms (large surface area per unit volume of nanoparticles = greater activity at low metal concentrations)
  • Human tissue (skin or other) has very low sensitivity to copper
  • Copper has a much lower environmental footprint than silver

Silver

Applications:

  • Antimicrobial applications: silver in water treatment (drinking water treatment and transportation), hospital care units, disinfection, working surfaces (i.e. door handles), textiles, and other antimicrobial applications

Key selling points:

  • Nanoparticles provide unique bactericidal mechanisms (large surface area per unit volume of nanoparticles = greater activity at low metal concentrations)

Titanium Oxide

Applications:

  • Coatings in medical devices
  • Filler pigment in cosmetics, pharmaceuticals, food products (such as E171) and toothpaste
  • Used in sun block creams due to its photostability

Key selling points:

  • Brightness, photostability, high refractive index
  • UV absorbing properties

Zirconium oxide

Applications:

  • Implant devices (dental implants, ball heads for total hip replacements)

Key selling points:

  • Toothlike colour
  • Biocompatibility, low plaque affinity
  • Exhibit minimal ion release compared with metallic implants
  • High refractive index material

Iron oxide

Applications:

  • In vivo imaging applications: used to non-invasively track cells for development and monitoring of cell-based therapies or for further investigation of biological mechanisms such as cell migration, tumor growth, and metastasis
  • Improve biomedical imaging (MRI: Magnetic resonance imaging)

Key selling points:

  • Superparamagnetic and fluorescent cell labeling nanoparticle
  • Biocompatibility at low concentration, high magnetic saturation and functional surfaces

Hydroxyapatite

Applications:

  • Bio-ceramic for medical and dental applications (biomedical implants, bone regeneration, hard tissue engineering, drug delivery)
  • Commonly used in the fabrication of porous bone scaffolds
  • Coating for prosthetics
  • HA has been successfully used as a drug carrier, particularly for the slow release of Ibuprofen

Key selling points:

  • Biocompatible structure
  • Multi-functionality of the HA particles
  • Several morphologies available: particles, rods, sheets, tubes
  • Different lengths, diameters possible
  • Particle size controllable

Precious metals

Applications:

  • Biomedical imaging technologies (computer tomography)
  • Fluorophores (quantum dots, fluorescent semiconductor nanocrystals) forĀ in vivofluorescence imaging
  • Colorimetric biosensing
  • Palladium in dental inlays, crowns and bridges
  • Brachytherapy (palladium)
  • Water purification (remove halogenated volatile organic compounds from groundwater)

Key selling points:

  • Gold nanoparticles: biocompatibility, relatively low short-term toxicity, high atomic number and high X-ray absorption coefficient
  • Great brightness
