GENERIC TECHNOLOGY STÚLB™
MultiCoats uses STÚLB™ - laser based generic and unique technology for deposition of thin and ultra-thin films, nanocoatings and nanostructures. The agent deposited might be of (in)organic (including polymers, biopolymers, proteins) or complex materials on (in)organic or complex substrates in one device and within one technological cycle. The physical-chemical properties might be preliminary determinate. The technology provide means for strong and permanent control on the process.
Based on that,
MultiCoats' Labs and Divisions, in collaboration and cooperation with affiliate partners have developed several families of thechnology methods for coating and depositing wide range of materials..
 
Inorganic Coatings
 
DLC Thin & Ultra thin Films Tec    

Main Lab deposited DLC thin films on several different type of substrates, such as - SS-316 LMV, Teflon, ceramics, semiconductor materials for infrared optics (Si, GaAs, Ge, ZnSe as well.).
Cardiovascular Implants (stents) made of SS-316 and NiTiNol have been coated by Ultra thin film ta-DLC type.
There are two, completely different types of DLC films: a-C and ta-C. The materials differ in the index of refraction. Important distinction between them is whether they were condensed from energetic ions or from neutral carbon atoms. The most convenient means of recognition is whether the imaginary part of the index of refraction ni - 0,3 or ni - 0,7 respectively.
Presented DLC films have index of refraction ni within the range 1,3 - 2,4.

Metal Alloy M - 014 Ultra thin films Tec    

Nano Lab. Biocompatible & biodegradable metal alloy M-014 has been deposited as ultra thin film on polymeric, metal and ceramic substrates.
The alloy has fixed and sustainable rate of degradation implanted in tissue or within blood stream, wich makes it aplicable for drug(s) eluting matrixes..
Suitable for usage in Drug Delivery Systems as carriage - micro balls or rods or ultra thin film degradable cover of drug(s) container(s).

 
 
Metal nano particles incorporated within DLC matrix Tec [ MDLC Stent ]    

Nano Lab. Metal nanoparticles of Silver and Platinum are incorporated within DLC matrix coatings. The next step is to incorporate nanoparticles of Titanium and Zirconium within DLC matrix. Some Researchers as US NRL published info that "...DLC-silver and DLC-platinum composite films reveals ... self-assemble into particulate nano composite structures that possess a high fraction of sp3-hybridized carbon atoms. DLC-silver-platinum films demonstrated exceptional antimicrobial properties against Staphylococcus and Pseudomonas aeruginosa bacteria."
Nanostructures with highly controllable properties integrated whithin inorganic biocompatibles, polymers, biopolymers and biological system at nanoscale. might be used for applications in new hybrid nano devices with unique properties, . STÚLB™ is capable of forming hybrid nanostructures and biofilms in single technology cycle.

DLC Coatings on polimeric goffered Textile Substrate Tec    

MultiCoats. BioCoat Lab Division started deposition of nano films of DLC and/or gelatine and/or gelatine-drug-charged on goffer textile substrate, to be used as cardiovascular implant. Ultra Hydrophobic biocompatible hybrid material might be coated as well. The actual state of the textile surfsce is shown at microscopic photo picture to the left.
Normaly, the textile not treated by gelatine has water-permeability.of about 0.8 - 1.5 l/min/sq.cm and practicly zero after treatment.

Polymer P-312 Coatings Tec    

MultiCoats. Ppreparing some target samples for deposition of thin and ultra thin films of polymer P 312 (our designation), besides known properties, such as biocompatibility and biodegradability a photoluminiscence has been observed within "blue" part of the spectrum with responce time fare beyond 10 ns.
These biodegradable polyphosphoesters are appealing for biological and pharmaceutical applications because of their biocompatibility and similarity to bio-macromolecules such as nucleic acids.
P-312 has potential and properties to become gradient of Drug Delivery Systems.

 
 
Polymer D-712 Coatings Tec [Heavy metals Sensor device]    

MultiCoats' Division unit has started testing ultra thin polymeric films for heavy metal detection sensor device.
The Polymer D 712 (our designation name) and some of it's generations have shown properties usable for highly sensitive sensor made in form of Thin and Ultra Thin films..
Loooking for cooperation and partnership within FP7 of EU.

 
 
Polymer P-329 Coatings Tec    

MultiCoats' division BioCoat Lab has started depositions of biocompatible and biodegradable nano coats, based on P-329 polymer and its co-polymers, on DLC coated cardiovascular Stent, The polymer is to be charged by one or more drugs as drug carrier on as drug's cover-up thin film within drug(s) eluting matrix.
P-329 nano films might be coated (sandwich) by ultra thin layer of biodegradable and biocompatible metal alloy M-014 as mechanical protector,

 
 
PGLA (RG 503 H Poly-glyco-lactic-acid) thin film deposition Tec    

MultiCoats' division Main Lab using STÚLB™ laser technology performed controllable deposition of complex biopolymers and organic materials. Deposition on PGLA rezomer – synthetic biodegradable and biocompatible biopolymer in nano coats has been done and tested. Material is applied in pharmaceutics and stent manufacturing. Multi-layered films are deposited without any risk of harming deposited material properties onto any surface. The technology does not use any dissolving agent in any aggregate condition. Biopolymer bone structure analysis of these films have been quantified using Fourier Transform Infrared Spectroscopy (FTIR) for comparisons to native materials.

Polymer P-329 Coatings Tec    

MultiCoats' division BioCoat Lab has done controllable deposition of complex biopolymeric material known as Mioglobin B - synthetic biodegradable biopolymer, protein with mol. w. 17400 Dalton. The material is used in pharmaceutics and cardiovascular stenting. Multi-layered films are coated without risk of damaging agent's properties onto many substrates. The tec does not apply dissolvents and the target migt be in any aggregate condition. Myoglobin B thin films have been subject to structural analysis and quantified using Fourier Transform Infrared Spectroscopy (FTIR) for comparisons to native materials.
