Surface Coating / Alfa Chemistry

Customized Nanocoating on Different Substrates


Using techniques such as atomic layer deposition, nano coatings are utilized to seal materials at the atomic level (ALD). Nano-coating is a homogeneous molecular network in which molecules align to form a nano-structured network that protects the material it covers. Alfa Chemistry is a surface coating expert who develops and manufactures surface nano-coating technologies for modifying metals, glasses, and polymers. Our nano-coatings are made with extreme precision in order to build a homogeneous layer on every aspect of the surface. The opportunities and characteristics of various substrates vary.

Metal has a unique set of qualities, including strength, hardness, and durability. Alloys, on the other hand, have qualities like form memory and thermal or electrical conductivity. Prominent medical devices made of metal include:

  • Platinum/palladium vascular guide wire
  • The stainless steel injection needle
  • Nitinol stent

Our coating method allows us to provide equipment with the following features for metal products:

  • Without any PTFE friction reduction, it's custom-made for guidewires.
  • For diagnostic and bioanalysis, amine-functionalized metal oxide surface of sensor device chip.
  • To promote tissue integration of bioactive coated scaffolds, use peptides or growth factors.



Glass integrates positive and useful properties such as transparency, chemical stability and resistance to deformation. In medical technology and life science products, common glass consumables include:

  • Next Generation Sequencing (NGS) flow cell
  • In vitro diagnostic (IVD) microfluidic glass chip
  • Laboratory glassware

Depending on the requirements, Alfa Chemistry can process surface material properties to optimize applications. A few examples are:

  • Custom bonding of glass and other materials
  • Controlled protein-surface interactions in NGS and IVD products
  • Hydrophilic/hydrophobic surfaces in microfluidics
  • Patterned surface coating


Plastics are employed in a wide range of medical technology applications, particularly disposable items. It's a good material for mass production because of its low cost, although adhering to inert surfaces can be difficult. Pretreatments (corona plasma, etching, etc.) are commonly utilized in industry to create functional groups that are only temporary. Nevertheless, Alfa Chemistry gives permanent functionalization.

Perfluorophenyl azide (PFPA), which provides a non-specific insertion reaction to any carbon atom and is used in all types of polymerization, is typically used to achieve irreversible, chemically stable covalent bonding to plastics and polymers. It can be found in a variety of materials, including PTFE. Our coating platform can produce hydrophilic elastomers, viscous PTFE, and other incredible plastic surface properties.



Ceramics are commonly utilized in dental implants and filtration membranes due to their inertness, strength, and stiffness. In the case of the functionalization of ceramic surfaces, inertness can pose a problem. To mix several functional groups on a single polymer, Alfa Chemistry coating platform employs a multi-modal method. Even the most difficult heterogeneous interfaces, such as SiOx/TiOx multi-material products, can be coated using this method.


Semiconductor devices, such as integrated circuits (ICs) and logic semiconductor integrated circuits (LSIs), are used in a variety of electronic devices and have been developed to enhance density, performance, and miniaturization. Pretreatment is a set of processing procedures used in semiconductor production to prepare wafers cut from single-crystal silicon blocks. In many circumstances, coatings are employed in the manufacturing process for surface treatment, functionalization, and processing bonding. Coatings may be built on semiconductor materials like silicon and aluminum nitride using Alfa Chemistry's coating technology. It is used in a variety of processing settings, including surface treatment, and resists wafer coating or film formation. Integrated circuits are built on this basis.
