Blog post on Olympus objectives

Objective-ly good: read more on optics for improved single molecule sensitivity

A recently published blog post by Olympus Europe spotlights the integration of its X Line objectives into cutting-edge microscopy systems, such as our MicroTime 200. In the article, Marcelle Koenig, senior scientist at PicoQuant, talks about how the enhanced numerical aperture and improved chromatic corrections of the X Line objectives are beneficial for techniques such as Pulsed Interleaved Excitation (PIE) or Förster Resonance Energy Transfer (FRET) measurements.

Season’s Greetings

The days are getting shorter and Santa’s little helpers are very busy wrapping up PicoQuant’s traditional Christmas presents for all of our employees’ children. As in previous years, we are also raising funds to support a charity. Our financial support will go to Unicef.

Have safe and happy happy Holidays as well as a joyful New Year 2021, everyone!

Season’s Greetings

QRNG: Ten years of true random numbers

Nano-Optics group and PicoQuant celebrate 10th anniversary of their jointly created Quantum Random Number Generator

In 2010, the Nano-Optics group at the Physics Department of the Humboldt University and PicoQuant created a generator device that uses the randomness of photon arrival times to create random numbers of highest statistical quality. The generator and its associated web service have been running nearly 24/7 since then. Over these 10 years, the web service has delivered a total of 1.27 Petabytes of data to over 2000 users worldwide.

MicroTime 200 microscope for plant biology studies

A few research examples of our customers

In recent years, time-resolved methods such as FLIM, FRET-FLIM, and (scanning) FCS have been adopted for the study of plant biology. For example, the group of Thorsten Wohland used FCS to show that the disordered plant dehydrin Lti30 protects the membrane during water-related stress:

Ikram Blilou, Yuchen Long, and colleagues employed FRET-FLIM to observe cell-type-specific transcription factor interactions in living Arabidopsis roots:

For others to follow in this path, Stefanie Weidtkamp-Peters, Grégoire Denay, and colleagues published a practical guide for fluorescent protein selection in plant FRET experiments:

And recently, the use of FRET-FLIM and scanning FCS as novel tools in plant biology to determine protein dynamics at cellular resolution was covered in the Annual Review of Plant Biology:

Fortunately, PicoQuant`s MicroTime 200 confocal microscope and LSM upgrade kits all enable the rapid acquisition of precise and quantitative FRET-FLIM data, and the MicroTime 200 even supports scanning FCS data acquisition:

LMA 2020 Image Competition: Congratulations, Aria Ahmed-Cox!

Australian PhD student wins the 1st prize with entry depicting vesicle trafficking in brain cancer cells on MicroTime 200

The winners of the 2020 Light Microscopy Australia Image Competition have been announced. Over 100 beautiful entries competed for the top spots in the four categories Live Cell, Life Science, In Vivo, and Materials Science. Congratulations to all winners of this years fierce competition!

Among all of the winning entries, we’d like to highlight the submission “The Paths we Trace: Lifetime of Fluorescent Membranes in Cancer” by Aria Ahmed-Cox, a PhD Student at the Children’s Cancer Institute of the University of New South Wales. In her short video, she traced vesicle trafficking in brain cancer cells on a MicroTime 200 time-resolved fluorescence microscope using PicoQuant’s rapidFLIM approach.

With this entry, she won the 1st prize in the Live Cell category.

Congratulations!

Aria Ahmed-Cox’ work was conducted in collaboration with the Children’s Cancer Institute, Biomedical Imaging Facility, Mark Wainwright Analytical Centre, UNSW Sydney and the Faculty of Medicine, UNSW Sydney. She and her group thank the Cancer Institute NSW for their generous support and acknowledge funding from the NHMRC Program Grant (APP1091261) and ARC Centre of Excellence in Convergent Bio-Nano Science and Technology (CE140100036).
