VisiTech International Ltd.

The VT-iSIM features VTi's patented 2D-Array scanning architecture; enabling scan, de-scan, and re-scan of multiple points of illumination and emission, with just a single moving element. Each scan produces a complete image, delivering ultra-fast, full-frame capture rates of up to 500 Hz.

With instant SIM technology, the VT-iSIM delivers super-resolution images in real time, with no reconstruction or post-processing required. You get spatial resolution down to 100 nm, reduced photo-bleaching, and across a wide field of view. Faster. Clearer. Smarter imaging.

Due to our innovative 2-D array scanning architecture, large independent arrays of µLenses, and the instant nature of re-assignment, the VT-iSIM delivers class-leading performance in photo-bleaching when compared to standard array and non-array scanning confocals, @2x spatial and axial resolution.

Always a pleasure and never a chore to be at @mblscience.bsky.social Woods Hole for @omibs-mbl.bsky.social
Another wonderfully organised course with excellent participants. Thanks as always to the fabulous organisers, faculty, TA's, course directors and the amazing vendor faculty family 💚🦠🔬

The VT-iSIMz from VisiTech International delivers cutting-edge, live-cell, super-resolution imaging in a fully integrated, compact, and cost-effective platform, making advanced live-cell, super-resolution imaging more accessible than ever before.

Thank you to Ian Dobbie for organising a great workshop (in a very hot DC ☀️) on the commercialisation of imaging systems within bio-medical research, and for giving me the opportunity to discuss the story of the #VTiSIM. Great talks and great discussion.

Always a pleasure to support the Quantative Imaging @QIatCSHL course at Cold Spring Harbor Laboratory @cshlnews.bsky.social with our #VTiSIM... 💚🦠🔬

Another week another #VTiSIM Install.... this time @vuamsterdam.bsky.social. Thanks to our partners #Evident and #Hamamatsu.... Happy Imaging 😊🦠🔬

Another week, another #VTiSIM demo. This week we're at The Hong Kong University of Science and Technology, with our partners Chinetek Scientific.

The fun begins on Monday, and more updates to follow 🦠🔬💚

#FluorescenceFriday fixed cell data over the cell cycle in zebrafish embryo, Hoechst & IG against active enhancers and recruited Pol II. Recorded by @mofrawe.bsky.social on @visitech.bsky.social iSIM, prepared during Masters practical, credit also to @yuzhibao.bsky.social & TA Alicia Günthel

The crime was perpetrated thusly: a 15 µm z-stack of (n1)StayGold(c3)-CAAX in a U2OS cell imaged, with 200 nm spacing, every 30 seconds on a Visitech iSIM.

(scale bar = 5 µm)

Super‐Resolution Goes Viral: T4 Virus Particles as Versatile 3D‐Bio‐NanoRulers Various super-resolution fluorescence microscopy methods achieve nanoscale resolution, vital for visualizing subcellular structures. Choosing suitable biological standards is challenging, demanding p...

I am very proud to advertise our latest publication, "Super-Resolution Goes Viral: T4 Virus Particles as Versatile 3D-Bio-NanoRulers," in Adv. Materials: advanced.onlinelibrary.wiley.com/doi/full/10..... We propose to use T4 bacteriophages for calibrating 3D super-res fluorescence microscopy. 🧵

At KCL I could quickly test the iSIM (http://www.visitech.co.uk/vt-isim.html) from the @NikonInst Center - quite nice for a Z-stack aquired in ~10 seconds

Another iSIM upgrade, this time at ETH Zurich.
We've added our latest flat-field & full-field technology, as well as a second camera, FRAP and Cellsens (with our partners at Evident)..... Happy Imaging 🦠🔬

Flip the whole thing upside down and you have an upright microscope 🤣

We're all ready to go for the first iSIM demo at The Medical University of Vienna 🦠🔬😊

Always good to see packing material being repurposed... and in such fantastic fashion 🤩🤩

As is traditional with iSIM @visitech.bsky.social, we see things we never saw before.

The first noisy image from a faint sample- live ND7/23 cells transfected with NMDA receptors tagged with RFP & GFP.

But we never saw the membrane before...highly satisfying. More to come!

#FluorescenceFriday

Trying out inverted 3-color lookup tables in FIJI today. Here is recruited RNA polymerase II (red), elongating RNA polymerase II (black-ish), and DNA (blue). Fixed zebrafish embryo nucleus recorded with iSIM @visitech.bsky.social

Any suggestions for color combinations for three-channel composite?

New iSIM is really taking shape. Thanks to @visitech.bsky.social @humboldtuni.bsky.social @dfgpublic.bsky.social

We're strong proponents of re-purposing old microscope frames, to give them a new lease of life, but this may be a step too far 😂...... Where's the c-mount? 🔬🦠💚

Done!! 😊🙌

We're all excited to get the system up and running.... The first iSIM in Berlin 😁. No doubt our engineering team will work diligently to get the system installed, and Steve will rock up to take the glory 🤣... Only joking, see you soon 🔬🦠😁
