...An international student has been assigned to this program

A student from Taiwan has been assigned to our laboratory.

My name is Po-wei YI, from Taiwan and I am a PhD student with double degree in Applied chemistry, National Chiao-Tung University, Taiwan. My current research is engaged with “The assembling of protein mechanism through optical trapping”. Do the weight training to strengthen my muscle in gym is my hobby. Thanks for reading

Optical Trapping and Assembling of Protein at Solution Surface

We used the Rhodamine B-labeled lysozyme for observing the fluorescence image. The fluorescence intensity increases from the focus to the outside during the irradiation of trapping laser. The lysozyme concentration becomes locally higher with time, and their assembly expands to a few tens µm. After turning off the trapping laser, the highly concentrated lysozyme domain decreases to the initial value.

Fig. 1 Fluorescence images of the mixed D2O solution of lysozyme and Rhodamine B-labeled lysozyme upon laser trapping. The focus of 1064 nm laser is located at the center of the image.


The degree awarding ceremony was held on a smaller scale than in previous years, D3 Mr. Indra received his degree in our laboratory.

...Our Farm Diary vol.2

Our first crop turned out to be eggplant, zucchini, and peppers!
The other veggies are growing well, especially the watermelon ivy, which is looking amazing!

...Our Farm Diary vol.1

The vegetables were growing nicely during the stay home!
The tomatoes and zucchinies are starting to ripen and we can't wait to eat them!

A photo with the raked leaves (lol)

...Start farming

Students try their hand at farming in a rented field on campus!
Today we plowed the field and planted peppers, tomatoes, eggplants, watermelons, zucchinies, cucumbers, and okras.

We'll be posting growth records on an irregular basis! Stay tuned!

...Farewell party

We held a farewell party at Namba. Thanks to all the M2 students for their master's thesis presentations!
