Aquarray

A perfect combination: high-speed dispensing meets glass slides with functionalized surfaces that capture liquids without physical barriers!   Hydrophilic areas enclosed by a superhydrophobic surface allow precise control over the size, shape and placement of the dispensed microdroplets. On contact, the liquid is naturally drawn into the hydrophilic area. Droplet migration is prevented by local differences in wettability. The geometry of the spot, whether circular or rectangular, is determined by the surface design and not by the interaction between the liquid and the wetted surface. ⚡ In short, these hydrophilic anchors make life incredibly easy! ⚡   Why should you choose DMA-Slides from Aquarray? 💧 Droplet volume per spot from 10 nl to 5 µl 💧 Reproducible arrays/grids on slides streamline automated readouts 💧 Dispensed droplets are held stably in place due to the superhydrophobic background, improving reproducibility during sampling 💧 Wide range of patterns resulting in a range of 80 to 6048 spots per DMA, exceeding the throughput of microplates 💧 Standard microscope slide format with options for different coatings and spot geometries   Application example: biological assays ✔  Cell-based screenings ✔ Microscopic readout, e.g. fluorescence, morphology ✔ The number of cells required is low, between 1 and 5000 cells, depending on spot size ✔ Many experiments with rare cell types possible (biopsy) ✔ On-chip compound libraries pre-printed on the array   Details of the video: A DMA-Slide “203” from Aquarray was printed with a nanoliter dispenser on an iONE-1200 from M2-Automation GmbH. One shot with water, one with coloured ink, about 150 nanoliters per spot. Like all my videos… not rendered or AI generated and of course at real speed. The close-up was captured with Microqubic`s MRCL700 imaging system.   #microarray #medtech #screening #technology #highthroughput #hts #liquidhandling #Biosensors #Labautomation #Diagnostic #Genetictesting #moretimeforscience
