New ULS Equipment - Nikon AX R MP Upright Multiphoton Microscope

The University Research Facility in Life Sciences (ULS) has been supported by the Collaborative Research Fund (CRF) 2021/22 to acquire a Nikon AX R MP Upright Multiphoton (MP) Microscope.  The system is equipped with a dual-output pulsed laser for simultaneous multi-channel MP imaging and/or photostimulation, and supports high-speed intravital imaging using small animals. The system has been installed at the newly built Animal Imaging Centre (AIC) on Podium of Block Y and is now open for booking.   To introduce the major functions and applications of the new system, the ULS is going to hold a number of demonstration sessions on 5th and 12th July.  Online registration is now open until 2nd July.   Please contact Dr Michael Yuen for enquiries of the equipment or the demonstration.   Thank you for your attention.

Migration of PolyU ULS online booking system to URFMS (8)

ULS has kicked off the migration of the online booking system to University Research Facility Management System (URFMS, https://urfms.polyu.edu.hk/) since 2022.
