The Hong
Kong Institution of Engineers (HKIE) – Manufacturing & Industrial Division and
Biomedical Division co-organized the seminar named “When Electronics Meets
Medical Science – A case study of biomedical research and development, from
concept to business launch” on 11th Aug 2018. Lab-On-Chip (LOC)
technology integrates one or several laboratory tests on a single chip of only
millimeters to a few square centimeters to achieve a high-throughput screening.
LOC enables us to deliver accurate assays with extremely small fluid volumes
down to pico-liters, therefore, a microfluidic LOC platform was the dream
device in environmental and biomedial sectors.
Before seminar, Ir. SC Ho (Immediate past chairman, MID, HKIE) presented
a souvenir to the guest speaker Mr. William Yam, then took a group photo with committee members.

Mr.
William Yam (Founder of Sanwa BioTech Limited) was the guest speaker. Firstly, he introduced manufacturing processes
from components to assembly and then to micro technologies included
micro-joining, micro-machining and micro-assembly.
In order
to cut the material sharply and high precision, laser micro machining was
discussed. Because different material
absorption wavelengths were different, they could control the pulse and energy
to achieve very precise requirement. He
also showed some examples such as the WT logo machining on a fly wing.
Then Mr.
William Yam briefed the biomedical application included the machining with UV
short Pulse Laser. The left diagram micro
device was used to dilute/mix fluid samples.
He also
stated the smart LOC systems from 1st Generation to 2nd
Generation and then to 3rd Generation. He said one drop of blood would be detected
different diseases and though internet for more different application in the
latest technology.
Another
concept was integrated microfluidic chip for blood cell viability
analysis. Mr. William Yam said the
diagram of red blood cell was about 6um and it could pass 3um width channel of
microfluidic chip. One of applications was
for red blood cell analysis. Some diseases
would affect the size distribution of red blood cell. The vision of his company “Sanwa BioTech Limited”
aimed to provide leading edge microfluidic technology with tools and service
support to IVD market with fast and accurate detection, so as to achieve “One
drop of sample, multiple results in minutes”.
Finally,
he introduced their design concept named “ALiATM ideal model”
included LOC, IOT and POC. Comparison
with traditional methods (wet laboratory testing), their solution had advantages
in speed, accuracy, simplicity, multi screening, convenience and small, etc. Moreover, they had many public demonstrations
locally and internationally.
After the
seminar, Mr. William Yam demonstrated some LOC to us.
