Announcement: Free Widefield Light Microscopy Training for Students

The light microscopy training will cover the basic imaging formation principles as well as provide hands-on experience on how to optimize the widefield light microscopes ( for different applications. Samples such as nanoparticles, cells, tissues, mineral thin sections, etc. will be used in the training. Students are also welcome to bring their own samples of interest for the training if it is possible to be imaged on the microscopes. Different imaging modes, including brightfield, darkfield, phase contrast, differential interference contrast, polarized light, and epi-fluorescence imaging modes will be introduced to the trainees. The training will take place in PSC835. Students who are interested in the training can contact Dr. Kuangcai Chen ( for more details.

This microscopy training opportunity can prepare students for their future careers in academia and in the industry as the training in modern microscopy is a transferrable and marketable skill. This training is financially supported by Student Technology Fee (FY21, 21-IST 006 and FY22, 22-IST 007).

05/27/2021 – Working Protocol Updates

Following the new CDC and GSU guidelines, the Confocal Facility users in the Imaging Core Facility are not required to wear a mask, and users that are not fully vaccinated are strongly encouraged to wear a mask, and to maintain the 6 ft social distancing. Starting this moment, you can make your reservation requests without leaving a 15-minute gap. We will also allow maximum 2 users in room 839-A, and 3 users in room 839-B.

04/06/2021 – LSM 700 and 780 are back to service

All the issues have been resolved on both LSM 700 and 780 and they are back to service now.

04/01/2021 – LSM 780 out of Service

The LSM 780 is out of service; the computer does not turn on. A service call has been placed and the engineer will come next Tuesday to diagnose the problem, and hopefully, it can be fixed that same day. All the reservations made until Tuesday are canceled, Reservations from Wednesday and on remain, for now, providing the computer is fixed on Tuesday.

03/29/2021 – LSM 700 out of Service

The LSM 700 is out of service. Zeiss has been contacted to obtain replacing parts. The downtime is estimated to be around one week. Users will be notified as soon as the issue is resolved.

10/20/2020 – Winter Break Notice


As the Holidays and winter break are getting close, the confocal reservations for coming to work in PSC-839 during that time need to be planned with enough time to grant access to the room.

Go ahead and plan your reservations; the deadline for submitting your requests is:

MONDAY DECEMBER 14, 2020, 12:00 (noon).  

You have 2 weeks from today (11/20/2020) to plan your work.

Only users authorized to work afterhours will have access to the room during the Holidays.

Be aware that any request to reserve the Confocal after the deadline is going to be rejected, NO EXCEPTIONS!

You can start to make new reservations on Monday, January 4, 2021, next year.

If you have any questions, contact Ms. Claudia Sanabria (

10/16/2020 – Working Protocol for Confocal Updated

The new minimum mandatory time gap between users is reduced to 15 minutes. This means that the users must respect the time length of their reservations, which should include data transfer, so surfaces can be disinfected, and the disinfectant has time to act before the next user goes to work.
Every user needs to be aware of users that come to work next, be aware of the time, and be aware that every reservation is taken into account for other users to plan their activities in the confocal facility, according to how the Confocal Reservation Calendar is populated by the reservations.

09/15/2020 – NI Professor Dr. Charles Derby’s Paper Published in The Biological Bulletin with SEM Data

NI Professor Dr. Charles Derby’s paper (Chemosensory Basis of Feeding Behavior in Pacific White Shrimp, Litopenaeus vannamei, has been accepted by the Biological Bulletin Journal and published online. Check out more details on how they use SEM to image shrimp’s major chemosensory organs.

08/10/2020 – Working Protocol for Confocal Updated

In view of the evolving situation of the COVID-19 pandemic, the working protocol for working in the confocal lab was established. The updated version can be founded on the facility website ( The protocol may subject to change.

07/21/2020 – Confocal Reservation Calendar

In order to provide transparency of who access the confocal rooms, a public calendar showing the confocal reservation activities is made available. The calendar can be accessed through our website (, under “Confocal Reservations –>> View Reservations”.

06/22/2020 – Working Protocol for using Confocal during the Pandemic Established

In order to protect the health and safety of the users and staff, a working protocol for using confocal during the pandemic is established. All users and staff are required to adhere to the rules and policies to minimize the risk of exposure and/or potential transmission of SARS-CoV-2 virus.
