For another year, microLIQUID will be exhibiting at AACC 2018 (Annual Scientific Meeting & Clinical Lab Expo) which will take place at McCormick Place, Chicago, IL, USA (July 31-August 2).
On behalf of our company, if you are attending to the event, we want to take advantage to have a meeting with you in order to talk about our common interests.
See you soon!
The use of durable replica moulds with high-feature resolution has been proposed as an inexpensive and convenient route for the manufacture of microstructured materials. A simple and fast duplication method, it involves the use of a master mould to create durable polymer replicas, using polydimethylsiloxane (PDMS). The application of PDMS offers numerous advantages due to its intrinsic properties such as its biocompatibility, affordable price, transparency (240nm-1100nm) as well as its low autofluorescence. The replica process enables fast and easy manufacturing since it can be covalently stuck to a glass substrate, using plasma treatment to form sealed microfluidic devices. The replica process is clean and precise, while multiple replications can be obtained from one master. This dramatically decreases both the expenditure and the time required to create specific patterns that need to be used consistently in the creation of various devices.
microLIQUID manufactures polymer SU-8 master moulds on silicon wafers, which are widely used to produce microfluidic disposables in the development and prototyping stage. In addition, we generate series of PDMS copies with excellent reproducibility and precision. microLIQUID offers high resolution moulds with a standard deviation of under 2%. microLIQUID is working in applications such as droplet generation for PCR diagnostics, single-cell analysis and high throughput screening among others. The moulds are highly reusable since we offer several treatments to increase the service life of the mould. This replica method will help you choose the optimum design for your product prior to scaling up to mass production. Indeed, more than 50 companies all over the world have already done so.
The company is now celebrating a decade working on the design and manufacture of novel microfluidic products for our customers; we are proud and delighted to have made it this far, and excited about the future!
During this time, we´ve grown in many ways, for example by increasing the number of employees and clients, as well as boosting revenues. We have collaborated successfully in more than 300 microfluidic projects around the world, doubling our turnover since 2014 and we have gained vast experience in this business dimension. In addition, we develop new value propositions to our customers, offering unique complete value chain solutions from complex microfluidic consumables that can be processed on our own design automated instrumentation (e.g. Point of Care instruments).
Since its establishment, microLIQUID has focused on delivering quality to its customers and fulfilling their expectations. This is the reason why so many of our clients and partners trust our professionalism and appreciate the individual approach we provide.
We are grateful to all those who have worked with us and have helped us over these last 10 years to develop our company. microLIQUID´s success would not have come to fruition had it not been for their unwavering support.
We are optimistic about what lies ahead and are very confident that we will be able to help many more future customers around the world to manufacture solutions based on our microfluidics and automated instrument solutions in fields such as rapid testing, immuno-oncology, NGS and Precision medicine, liquid biopsy and drug delivery among others.
microLIQUID will be at the 2017 AACC Clinical Lab Expo this August 1-3 in San Diego, CA.
AACC is a global scientific and medical professional organization dedicated to clinical laboratory science and its application to healthcare. Their leadership in education, advocacy and collaboration helps lab professionals adapt to change and do what they do best: provide vital insight and guidance so patients get the care they need.
On behalf of our company, if you are attending to AACC, we want to take advantage to have a meeting with you in order to talk about our common interests.
We will be pleased to invite you to join our booth #630, where we will be showcasing our latest offerings and technologies, and we will have our top product experts on hand to answer your questions.
Looking forward to seeing you.
Microfluidics: Chemotaxis and ADVANTAGES
it is known microfluidics nowadays is revolutionizing the way the motile behaviour of cells are studied.
It has enabled observations at high spatial and temporal resolution is carefully controlled microenvironments.
Taking into account both of the parts, chemotaxis and microfluidics, there are some advantages when using them two together:
– Presents experimental challenges that are not observed on chemotaxis studies of surface-adherent cells.
– Generate steady, arbitrarily shaped chemical gradients.
– Unique control over the chemoattractant gradient and the migration environment of cells.
– Provide spatial and temporal control over a reproducible chemical environment.
– Enables building well defined and stable chemical gradients at cellular length scales.
– Provide a platform for quantifying cellular responses at cellular and molecular levels.
Microfluidics Application: Chemotaxis
When an organism moves in response to a chemical stimulus it is said that Chemotaxis has happened.
Due to some chemicals that are in the environment the organisms, such as Somatic cells, bacteria, single-cell or multicellular organisms, direct their movements.
When the chemotaxis movements occur toward a higher concentration of the chemical, it is said that is a positive movement.
On the contrary, when the movement is done in the opposite direction, toward the lowest concentration, it is said that is a negative movement.
In addition, if it is nondirectional or randomly directed, the chemotaxis will be called Chemokinesis.
Chemotaxis is done with two independent chemoattractants.
Even if they are independent, we can say that they are interrelated processes-motility and directionality and both of them are regulated by extracellular stimuli.
Electrophoresis using Microfluidics – Main Advantages
Advantages of using electrophoresis with Microfluidics:
1. Improved Diagnosis, simplified diagnostic procedures, faster treatment and results.
2. Simplicity; Fast and easy technique.
3. Low cost material.
Electrophoresis and Microfluidics
Electrophoresis is an analytical method which is applied for the separation and characterization of proteins, nucleic acids and subcellular-sized particles such as viruses and small organelles.
Its principle is that the charged particles of a sample migrate in an applied electrical field.
Electrophoresis of positively charged particles (cations) is called cataphoresis, and on the other hand, electrophoresis of negatively charged particles (anions) is called anaphoresis.
Electrophoresis is a technique used in laboratories to separate macromolecules based on size.
Flow Cytometry : Advantages of using Microfluidics
Positive aspects about Flow Cytometer based on Microfluidics:
1. To have a high purity and recovery for the sorted cell population.
2. To sort based on an intracellular characteristic in which magnetic beads would not have access.
3. To sort cell labelled with fluorescent probes for nuclear or other intracellular targets.
4. To have information about cell surface molecules.
5. To sort different receptors even if they are low in density.
6. To sort cells according to absence, density or presence of the receptors.
Flow Cytometry using Microfluidics
Flow cytometry is a laser-based technology used in cell counting, cell sorting, biomarker detection or protein engineering.
By suspending cells and passing these suspending cells by passing them using an electronic detection machine, flow cytometry is done.
This technique allows making simultaneous analysis of the different characteristics of the more than a thousand particles per second.
This technique is usually used in the diagnosis of health disorders, in most of the cases blood cancers, but it is used in many medical trials, such as to sort particles according to their properties or purify populations of interest.
