Textile x Bio x Digital Fab Study Group: Biofabricating Materials

In the first week of the Fabricademy Study Group, we started experimenting with different biofabricating materials that can be used in the textile industry. We conducted 4 experiments: the Kombucha leather, Salmon fish skin leather, coffee ground leather and gelatin-based bioplastic.

You can find the recipes we used in DIYBIO Hong Kong wiki page.

If you are interested to join us in making biomaterials, join the meetup every Thursday from 7PM to 9PM at MakerBay Tsuen Wan.

Bug Keeping Updates #1

Team: Ben & Reynald De Guzman

As we know, there is one track in DIY Bio Bug Hunt program that is based around insect rearing; Hence we are going to post our own documentations on different insects that we have been keeping on this blog, and hopefully we can share and exchange our own experiences with everyone.

Let us first dive into what I have been working on lately~

I recently went on a trip to Lamma island, and I had a blast; It is like a bug catchers paradise~ One of the start insects I have came across is the grasshopper seen as the cover of this blog post. I found it close to the hill tops on the bushes next to the trail, it blends in surprisingly well with the foliage despite of its vibrant colors. I collected 3 individuals hoping to get a breeding pair, together with them I also collected a sample of the plant I found them on (Still yet to be id).

Later on after going through reference books, I found out that they are known as monkey grasshoppers, more specifically I have identified it to be Erianthus dohrni.

I kept them in a plastic tub temporarily until I get my hands on an enclosure, and one thing I have observed so far, they defecate a lot.

More updates will be made about them shortly~ stay tuned.

Let’s Talk Bio! Science x Art = Knowledge Revolution

It is our great honor to have Dr. Yun Wah Lam as our speaker in the Science x Art = Knowledge Revolution talk last week at MakerBay Central. This talk is one of the public lecture from the Let’s Talk Bio! series organised by DIY BIO Hong Kong at PMQ. This is the most popular talk among our previous talks so far. In the talk Dr. Lam shared his personal journey in the teaching of science to art students in CityU’s newly created bachelor programme of Art and Science (BAS). Illustrated by student projects, he also tell you why a dialogue between artists and scientists can lead a new intellectual movement.

Date: 25 May, 7:00 PM – 8:30 PM

Location: MakerBay Central, PMQ H508

About Dr. Yun Wah Lam

Dr Yun Wah Lam was born and educated in Hong Kong. After obtaining his PhD in biochemistry from the University of Hong Kong, he moved to Dundee, Scotland in 1998 to work as a postdoctoral researcher in the Wellcome Trust Centre in Cell Biology. He returned to his hometown in 2007 and joined City University of Hong Kong as an assistant professor. He built a multi-disciplinary research network, consisting of biochemists, chemists, materials scientists and medical doctors, to tackle a variety of biological projects, ranging from environmental sciences to regenerative medicine. Yun is also highly passionate about education and popularisation of science. He teaches on a range of subjects, including genetics, analytical biochemistry, and systems biology, and has developed several innovative courses for City University’s Gateway Education programme. Outside work, Yun is a keen lover of art and design, an amateur illustrator, writer and collector of useless facts.


Some takeaways from the talk:
  • Science is not always about applications. The exploration and discovery element is always neglected in the modern world.
  • When looking back to the great inventors in history, for instance Leonardo Da Vinci, the Wright brothers, Mendel etc. They did not constrain themselves to think solely like a scientist or engineer, but were actually incorporating different disciplines during their inventing journey. To be more precise, they don’t really have a mindset of specialisation. This help them tear down the artificial boundaries between knowledge pools.
  • The students’ work remind us of the joy of making discoveries and curiosity on the surroundings.
  • The mental burden of “usefulness, meaningful to civilisation, profitability” always stop me from doing science.
  • Everyone can do science simply just for fun just like doing art!

DNA Barcoding 2 Day Workshop in Hong Kong

How did you spend your easter holiday? Our team had spent a wonderful weekend with 11 kids in our community biolab, learning DNA barcoding, its applications and some basic molecular biology skills. This was our very first workshop of our Hong Kong DNA Barcoding project. It was held on 15-16 April at our community biolab at MakerBay. There was totally 11 kids, from 8 to 15 years old joining and some parents also participate in the process.

We kickstart our day with a brief introduction of DNA Barcoding and why we do barcoding, then we went out to Lei Yue Mun to collect plants samples and document the collected samples on iNaturalist app. The kids made several new discoveries. One of the 8 year old boy, Joe told us “I didn’t think of plants also have DNA! I thought only human have DNA.” Another girl, Amber, also found that some plants look very similar but when she touched the leaves, she discovered that one plant species actually has hair on the leaf surface while another doesn’t.

We then returned to the lab with the specimen and isolate the DNA from the plant samples. The kids have great interested on using micropipette and centrifuge. Joe was so excited that he even drew out the the lab and the equipments and gave us as a gift.

In day 2, the kids learnt about how PCR works and prepared PCR reaction mix for their own samples. After 2 hours, they took out their PCR products, learn casting agarose gels and analyze the amplified DNA by gel electrophoresis. Below shows the gel photograph:

Though some samples shows no band, we still got 60% successful rate. Yet this was a good learning experience for both us and the kids!

First testing of the DNA Barcoding Project in the DIYBIO Hong Kong community lab!

What is Barcode Hong Kong Project?

The Hong Kong Barcode Project is a citizen science program in Hong Kong. Just like the unique pattern of bars on the products in supermarket, a DNA barcode is a DNA sequence that uniquely identifies each species of living thing. The Hong Kong Barcode Project aims to engage general public using DNA technology to explore biodiversity in Hong Kong.

Projects can use DNA barcodes to examine any aspect of the environment, such as:

  • Sampling biodiversity in a park, garden, office, or school;
  • Checking for invasive plant or animal species;
  • Monitoring disease vectors;
  • Identifying exotic or endangered food products in markets; and
  • Detecting food mislabeling.


Our Barcoding First Test

As a DIYBio community, we decided to run our first testing in a DIY way. We used DIY lab ware like 3D printed gel electrophoresis tank, Blue LED transilluminator and DIY DNA extraction method.

We collected two plants sample nearby our lab and recorded their geographical location in iNaturalist app. We did the DNA extraction using commercial kit as well as our homemade DNA extraction recipe.


Our results

Yeah! We got our DNA bands! It proves our DIY DNA extraction methods and PCR works. Though there are still some adjustments needed to be made.

Our next step

Improve and run again to make the process goes more smoothly. Then we will organise a Barcoding workshop in our meetup to invite general public to try doing wet lab like a DIY biologist! Ultimately, we would like to provide education to general public.
