Nanomaterials for Targeted Drug Delivery & Photothermal Therapy

Gold Nanoparticles:

Since 2004, nanoComposix has provided monodisperse and unagglomerated metal and metal-oxide nanomaterials to thousands of customers. Hundreds of different variants of material, size, shape, and surface are available as stock products and we have produced over 2000 custom core/shell, biofunctionalized, fluorescent, and magnetic nanocomposites to meet client specifications.


  • Gold nanoparticles are readily conjugated to antibodies and other proteins due to the affinity of sulfhydyl (-SH) groups for the gold surface, and gold-biomolecule conjugates have been widely incorporated into diagnostic applications, where their bright red color is used in home and point-of-care tests such as lateral flow assays.
  • Gold nanomaterials can be conjugated to biomolecules to specifically target cancer cells and used for photothermal cancer therapy, where their tunable optical properties cause them to convert laser light into heat and selectively kill cancerous cells.
  • Gold nanoparticles have unique optical properties because they support surface plasmons. At specific wavelengths of light, the surface plasmons are driven into resonance and strongly absorb or scatter incident light. This effect is so strong that it allows for individual nanoparticles as small as 30 nm in diameter to be imaged using a conventional dark field microscope.

Silver Nanoparticles:

Silver nanoparticles are widely incorporated into wound dressings, and are used as an antiseptic and disinfectant in medical applications and in consumer goods. Silver nanoparticles have a high surface area per unit mass and release a continuous level of silver ions into their environment. The silver ions are bioactive and have broad-spectrum antimicrobial properties against a wide range of bacteria. By controlling the size, shape, surface, and agglomeration state of the nanoparticles, specific silver ion release profiles can be developed for a given application.

Conductive Composites

Incorporation of silver particles into plastics, composites, and adhesives increases the electrical conductivity of the material. Silver pastes and epoxies are widely utilized in the electronics industries. Silver nanoparticle-based inks are used to print flexible electronics and have the advantage that the melting point of the small silver nanoparticles in the ink is reduced by hundreds of degrees compared to bulk silver. When scintered, these silver nanoparticle-based inks have excellent conductivity.


Silver nanoparticles have unique optical properties because they support surface plasmons. At specific wavelengths of light the surface plasmons are driven into resonance and strongly absorb or scatter incident light. This effect is so strong that it allows for individual nanoparticles as small as 20 nm in diameter to be imaged using a conventional dark field microscope. This strong coupling of metal nanostructures with light is the basis for the new field of plasmonics. Applications of plasmonic silver nanoparticles include biomedical labels, sensors, and detectors. It is also the basis for analysis techniques such as Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Fluorescent Spectroscopy.


There is increasing interest in utilizing the large scattering and absorption cross-sections of plasmonic silver nanoparticles for solar applications. Since the nanoparticles act as efficient optical antennas, very high efficiencies can be obtained when the nanoparticles are incorporated into collectors.

Custom Nanoparticle Synthesis


NanoComposix has a multi-disciplinary team of scientists with backgrounds in chemistry, physics, engineering, and earth sciences. They 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; standard products can be modified or new materials developed as per the research needs.

Other Services:

DLS Analysis, Endotoxin Testing, ICP-MS, TEM Analysis, UV-Vis Analysis, & Zeta Potential Due to their small size, low mass, and extremely high surface area-to-volume ratios, once nanoparticles bind together, it is often impossible to separate them. Consequently, most dried gold nanopowders that are resuspended consist of clusters of hundreds of individual nanoparticles. For many plasmonics and biomedical applications, this agglomeration significantly degrades performance. To overcome these challenges, we provide custom processing techniques that allow us to concentrate and purify nanoparticles without inducing agglomeration. The particles can be transferred into a variety of different solvents to enable their integration into a wide variety of systems. In addition, we have developed a surface stabilization technique that allows us to produce dried gold nanoparticles that can be redispersed into individual, monodisperse nanoparticles.

We, BTL Biotechno Labs Pvt. Ltd., a distributor of nanocomposite, offer their complete range of products to bring nanotechnology-enabled products to market in India. For nearly 20 years, nanocomposite has provided monodisperse and unagglomerated metal and metal-oxide nanomaterials to thousands of customers for varied uses, including Lateral Flow, Drug Delivery, Plasmonics, Optical Engineering, Surface Coatings, and more.
