Single Cell isolation

As we have entered an age of personalized medicine, we have begun to understand that individual differences play a large role in disease expression and treatment options. This idea is also true of individual cells, the basic unit of life. Therefore, when studying disease phenotypes and developing new drugs, it is becoming increasingly important to study single cells instead of groups of cells. The technologies used for single cell isolation have started to improve and it is now possible to isolate single cells for analysis. Oftentimes, this analysis is referred to as cell omics because it covers a wide range of topics including genomics (DNA), transcriptomics (coding and non-coding RNA), proteomics (protein), and metabolomics (the complete set of small-molecule chemicals found within a biological sample). This is a lot of information to gather from such a small, but powerful structure, and it can become very valuable when studying diseases such as cancer, which generally arises from a mutation within a single cell

Gold Nanoparticle Synthesis strategies

Gold has always held a special allure for humans throughout history: wars were fought over it, alchemists strived to turn other metals into it, graves were looted for it, and love was sworn by it. Gold is so entwined in our lives that many people don’t even realize that it is fundamental to many state-of-the-art biotechnology. One of the most useful modern properties of gold is the creation of a surface plasmon resonance condition upon exposure to incident light of a resonance frequency. Gold used in this way is applied as a thin layer on a surface plasmon resonance (SPR) chip or is used as nanoparticles in Surface Enhanced Raman Scattering (SERS). These aqueous solutions of gold nanoparticles (5-50 nm in diameter) are the least recognizable form of gold because these colloidal solutions actually appear reddish in color rather than the characteristic yellow color of larger solid gold. It turns out that the work of the alchemists was not wasted. The discovery of aqua regia (noble or royal water) by an alchemist in the 8th century AD is critical to gold nanoparticle synthesis. This powerful mixture of nitric acid and hydrochloric acid is capable of dissolving solid gold to make chloroauric acid, which is the starting point for gold nanoparticle synthesis.

Magnetic cell separation processes in 3 steps

Cell separation is widely used in research and clinical therapy. For research purposes, sorting cells from a heterogeneous population enables the study of the different isolated types. From a therapeutic perspective, cell separation allows for the therapeutic infusion of enriched cell populations into a patient. Moreover, the latest advances in stem cell therapy, tissue engineering and regenerative medicine show the potential of cells derived from different tissues. The use of highly selective separation processes is critical to improve the quality of these cell-based treatments.

How advanced biomagnetic separation systems solve most of your cell sorting problems

Sorting cells from a heterogeneous population enables the study of the different isolated types, but also allows for the introduction of enriched cell populations to a patient. The use of highly selective separation procedures is also critical to improve cell-based treatments on stem cell therapy, tissue engineering and regenerative medicine.

3 problems when using classical magnetic separation rack in cell sorting

Biomagnetic cell separation is an alternative to centrifugation, columns, filtration and precipitation. It eliminates undue cell-stress and reduces the risk of negative impact on cell function and phenotype.
