Mechanism and function:
As a sensor material: PtNPs and AuNPs have a synergistic effect and improved catalytic efficiency. They can be used as biological and electrochemical sensors to detect various substances such as ethanol, hydrogen peroxide, glucose, and mercury ions in aqueous solutions.
As a catalyst: It has high catalytic performance and can be used as a catalyst for a variety of reactions, such as oxidation reaction of formic acid, reduction reaction of 4-nitrophenol, HER reaction, ORR reaction, etc.
As a special optically active material: a platinum-gold alloy nanomaterial with a special morphology responds to near-infrared light and produces a special thermal effect. This "photothermal effect" can also be used for anti / bacteriostatic purposes with significant effects.
Nanogold
The company is a large-scale production and commercial application of gold nanorods with a size (20-50nm rod length). It is a rod-shaped nano-gold that does not use CTAB internationally. Because the nano-gold rod has surface charge, under the influence of light, two different types of plasma resonance absorption peaks are generated along its surface, corresponding to In the visible (~ 520nm) and near infrared (~ 800nm) bands. Among them, in the near infrared (~ 800nm) band, biological tissues and body fluids have the least absorption and scattering of light in this band, and the highest light permeability. It can be used in beauty skin care, photocatalysis, biomedical diagnosis, rapid disease screening, food testing, etc. field.
Performance advantages of patented nano-gold rod composite materials:
1.Specific surface area, high activity;
2, small size, strong penetration in cell tissue;
3. Small scattering and high absorption ratio;
4. Two-photon fluorescence quantum efficiency is high;
5. Coupling is sensitive to distance and material type;
6. There are relatively many "hot spots" in the assembled dense film, and there are multiple strong coupling "dots";
7, does not contain toxic cationic surfactant CTAB;
8. Good hydrophilicity;
9, good dispersion, uniform and stable dispersion;
Application:
Biomedicine:
Cancer diagnosis and treatment, targeted drug carriers, skin repair, bio-imaging, detection of various toxic substances, rapid detection reagents, etc.
Beauty skin care:
Firming anti-aging, hydrating and soothing, repair and isolation.
Compared to the sky-high procurement costs of graphene and fullerene, the procurement cost of nano-gold with the same functional efficacy is much more affordable, and it is more suitable for application in the formulation system. Ankang Demei uses the most advanced nano material production technology to mass produce high-quality nano-gold composites (gold nano-rods) and promote its commercial application prospects. We are committed to building Ankang Demei as a pioneer in the development and production of materials in the field of nanotechnology beauty in China, always standing at the highest point of the overall industry chain of nano-gold skin care, leading the innovation and development of nano-technology beauty in China.
Nano silver
Nano-silver is nano-scale metallic silver simple substance, and the nano-silver particle size is usually between 1-100nm. Nano bactericidal mechanism: After binding with the cell wall / membrane of pathogenic bacteria, it directly enters the bacterial body and combines with oxygen metabolism enzyme (-SH). It suffocates the bacterial body and suffocates it. At low concentrations, it can quickly kill most of its bacteria, More than 650 microorganisms such as fungi, molds, and spores. Ankang Demei re-chitosan nano-silver composite material, through the graft modification of chitosan, not only improves its water solubility, broadens the application field, but also retains the original antibacterial properties and gels. It is spherical and loaded with nano-silver composite with a particle size of 20-50nm, which can make nano-silver uniformly dispersed in chitosan without aggregation, and can achieve the synergistic effect of the antibacterial effect of the two. Materials with bactericidal mechanism, broad-spectrum bactericidal and without any drug resistance, can promote the repair and regeneration of damaged cells and promote wound healing and repair. Can be used as a medical antibacterial material in the field of beauty and skin care.
Performance advantages of patented technology for preparing nano-silver composites
1 Broad-spectrum sterilization without drug resistance;
2 Promote wound healing and repair;
3 Prolong antibacterial aging time by slow-release dispersing carrier;
4 Good dispersibility, uniform and stable dispersion, good stability;
5Good water solubility;
6 Good biocompatibility.
Carbon quantum dots
The new nanomaterials with carbon element as the basic framework structure have good dispersibility, small size, low toxicity and good biocompatibility.
Carbon quantum dots can be used as biological fluorescent markers: they can emit bright light when illuminated. The emission wavelength of carbon quantum dots depends on the excitation wavelength, and the quantum yield changes when the excitation wavelength changes. Carbon quantum dots have a wide range of excitation wavelengths, which facilitates the simultaneous detection of carbon quantum dots as biomarkers in multiple samples. Importantly, it is more biologically reliable than previous fluorescent materials and has less interference with biomolecules than other fluorescent labels. Therefore, it is expected to solve the safety problems of fluorescent materials in life research as a biomarker material.
Carbon quantum dots can be used for drug development: combining carbon quantum dots with fluorescent imaging methods can dynamically monitor the behavior of nanomedicines in living cells or animals in real time, and intuitively, quickly and accurately obtain the distribution of nanomedicines in objects, Important information such as transport, release, and pharmacodynamic mechanisms provide technical support for the design and development of clinical nanomedicines.
Performance advantages of patented carbon quantum dots
1.Good dispersibility, low toxicity, and good biocompatibility;
2 Biofluorescent labeling is more reliable and less interference.
