Ag2S Quantum Dots

It is well known that light from visible to NIR wavelengths (650–1350 nm) is noninvasive for detecting and imaging of abnormal tissue. The NIR optical window consist of the first near-infrared region (NIR-I; 650-000 nm) and the second near-infrared region (NIR-II; 1000-1700 nm). The NIR-II can be more conducive to imaging than NIR-I due to lower fluorescence and reduced light scattering. NIR-II QDs mainly include Ag2S, Ag2Se, Ag2Te, PbS, PbSe, InAs, Cd3P2, Cd3As2, CdTe, HgTe. However, the toxic elements such as cadmium, mercury, lead, and arsenic, have seriously affected their application in the biomedical field.

What’s So Amazing About Graphene? – Creative Diagnostics Blog

Graphene, which is actually stripped from graphite, is a two-dimensional crystal made up of carbon atoms with only one layer of atomic thickness. The graphite used for pencil leads is equivalent to countless layers of graphene stacked on top of each other. Graphene, which sounds ordinary, has many unique properties. Popularly speaking, in nature at present, this thing is the thinnest and strongest material with excellent electrical conductivity, almost omnipotent in the industrial field. How thin is graphene? The unfolded area of 1 gram of graphene is 2630 m2. Graphene has very low resistivity and electrons can move in it very efficiently, which makes graphene have very good electrical conductivity. Graphene also has the zero permeability characteristic of “needle can not be inserted, water can not be splashed into”.

Graphene has come into daily life With the development of scientific research, at present, graphene products begin to come into our daily life. Lateral Force Microscopy (LFM) - AFM Nanoprobes. Kelvin Probe Microscopy - AFM Nanoprobes. High Resolution Imaging - AFM Nanoprobes. High Aspect Ratio AFM Probes - AFM Nanoprobes. The spatial resolution of the surface imaged by the atomic force microscope depends on two properties of the tip: the radius of the tip and the aspect ratio.

High Aspect Ratio AFM Probes - AFM Nanoprobes

The aspect ratio refers to the ratio of the height and width of the AFM tip. The standard AFM probe made of silicon has a conical, pyramidal or tetrahedral tip. The conical tip can be manufactured to have a relatively high aspect ratio. However, these conventional probes cannot accurately solve the morphology of highly non-planar features, such as deep trenches and narrow trenches that are common in semiconductor device processing. This is because the height and width of the probe are shorter than the height of the side wall and wider than the interval between the side walls of the structure.

Solid Lipid Nanoparticle Production

Based on our deep understanding of solid lipid nanoparticle, our scientist team can provide professional solutions for solid lipid nanoparticle preparation and characterization. Introduction to Solid Lipid Nanoparticles Solid lipid nanoparticles typically contain a hydrophobic solid matrix core with one layer of a phospholipid coating (Figure 1), and it is typically spherical with an average diameter between 10 and 1000 nanometers. Solid lipid nanoparticles are prepared by using solid lipids (e.g., purified triglycerides, fatty acids, steroids, or waxes) that can solubilize lipophilic molecules, emulsifiers that stabilize the core, and water.

The hydrophobic tail regions of the phospholipid are embedded into the core matrix resulting in the core exclusively possesses a hydrophobic nature for drug encapsulation. Figure 1.

Drug Delivery Nanoparticles Formulation

Lanthanide-Based Magnetic Particles. Lanthanide-Based Magnetic Particles The Absolute Mag™ Lanthanide-Based Magnetic Particles is a kind of super-paramagnetic magnetic particles formed by the reaction of a strong lanthanide element (Ln) mono-electronic oxidant with Massart magnetite under high-power ultrasonic irradiation.

Lanthanide-Based Magnetic Particles

These particles have a γ-Fe2O3 core and are positively charged, hydrophilic, and not easy to aggregate in aqueous suspensions/ferrofluids due to electrostatic repulsion. Since the lanthanide elements have a characteristic oxidation state of +3 valence, it is readily reacts with the Lewis base, therefore, the particles can also be further functionalization. CAN-Fe2O3 Nanoparticles are especially recommended here for innovatively gene silencing application. Features: First « 1 – 5 / 5 » Last. Functional Quantum Dots. Creative Diagnostics provides water-soluble quantum dots with different functional groups, including amine, carboxyl, GSH (glutathione), and MPA (3-Mercaptopropionic acid).

Functional Quantum Dots

GSH or MPA quantum dots have the hydrodynamic sizes of 10-12 nm diameters, while PEG-NH2 and PEG-COOH quantum dots are about 20 nm in size. PEG functionalized quantum dots have much better performance in solubility and pH stability. Amine and carboxyl quantum dots available with a PEG spacer are ideal for covalent conjugation with proteins, antibodies and other biomolecules. Generally, our water-soluble functional QDs have great potential to be used in highly sensitive cellular imaging, molecular recognition and optical devices. Applications: Gold Nanoparticles Conjugation Kits.

Creative Diagnostics Conjugation Kits are excellent tools for early stage R&D to quickly selection for most adequate gold nanoparticles conjugates for your projects. Silica Magnetic Particles. Silica Magnetic Particles The DiagNano™ silica magnetic particles are produced by hydrolysis of orthosilicates in the presence of magnetite and have a hydrophilic surface with terminal Si-OH-bonds and can easily be separated with conventional permanent magnets.

They are extremely stable in organic solvents and at high temperatures. Silica coating not only contributes to the improved stability and prolonged shelf-life due to inertness of silica, but also facilitates the surface functionalization by providing various active reacting groups, including OH, NH2, COOH, SH, N-hydroxysuccinimide (NHS) and epoxy for the covalent binding of proteins, antibodies, or other molecules. It can also be used for nucleic acids isolation and purification though the DNA/RNA-silica interaction method created by Boom et al. in 1990, with improved efficiency and simplified operation. First « 1 – 20 / 45 » Last. Water and Wastewater Treatment. Water is an indispensable substance in human life and production. With the development of industry, the problem of water pollution has become more and more serious.

For example, heavy metals (such as Pb2+, As3+, Cu2+, Cr6+, Cd2+, Co3+, Mn2+, and Hg2+) in industrial production enter the natural water body with the discharge of industrial wastewater, resulting in heavy metal pollution in the water. Even at low concentrations, heavy metals can cause significant toxicity to microorganisms. People have paid a lot of attention to water and wastewater treatment. Nanomaterials have been actively researched and developed over the past few decades and have been successfully used in many fields such as catalysis, medicine, sensing, and biology.
