【Editor’s Note: The finals of the 8th China International College Students “Internet+” Innovation and Entrepreneurship Competition were held online on Nov. 10-13. Zhejiang University ranked 1st by clinching a record high 13 gold medals. Let’s take a look at those gold medal winning projects in this two-part report.】

EFL—A world-leading integrated supplier of 3D biological printing
The EFL team builds a complete scheme for bio-ink and the bio-3D printer, which can be applied to a wide spectrum of scenarios, such as 3D cell culture and micro-needle and micro-sphere preparation. It has, so to speak, cracked a hard nut in terms of high-end reagent consumption in domestic biological laboratories.

A diagnostic system for neurological disorders based on WEPCAST MRI
Neurological diseases affect nearly one-sixth of the global population, and the detection of the blood-brain barrier is the key to early diagnosis and treatment. To this end, the team develops a novel non-invasive WEPCAST MRI technique, which can assess the damage of the blood-brain barrier in five minutes. As compared with traditional techniques, WEPCAST MRI is featured by remarkable efficiency, great convenience, exceptional sensitivity and non-invasiveness.

Biothinker——FACS Sample Preparation Workstation
The Biothinker team is committed to promoting automation in biomedical laboratories. The Biothinker, a FACS sample preparation workstation, will help researchers automate a series of operations, including pipetting, incubation, blowing and washing, thus solving such problems as complex and time-consuming manual operations and high cell loss rates and ultimately improving the efficiency of research and diagnosis appreciably.

TruSense: A clinical testing and analysis platform based on personalized medicine
The TruSense team is devoted to designing and developing a customized paramedical service product for the non-invasive detection of the influenza A (H1N1) virus in saliva. The product can rapidly detect the concentration of the influenza virus in saliva by collecting a saliva sample from a patient and monitor the patient’s condition in real time.

CellBank—An animal cell cryopreservation service
CellBank is a technology- and service-driven one-stop provider for animal stem cell freezing and therapy. With the world’s leading stem cell storage technology, the team brings into full play its multiple collaboration with university laboratories, livestock farms, animal breeders, stem cell storage banks and animal hospitals to provide animal stem cell freezing and storage services for the treatment of future diseases that animals may suffer from, thereby providing a lifelong “health insurance” for animals.

TONKAN Tech: The world’s leading medical-grade respiratory ketone solution
TONKAN Tech is a medical-grade respiratory ketone solution provider integrating R&D, production, sales and service, and its major product is the real0time respiratory acetone analyzer. Through a series of world-leading technologies in vapor removal, gas enrichment and cavity enhancement, TONKAN Tech elevates the accuracy of respiratory acetone to the level of blood ketone detection, thereby brining good news to diabetes patients, pregnant women as well as sport and fitness people.

Paper Day—Socket-type retractable paper straw
The Paper Straw team prides itself on two core technologies—the high-speed rotary extrusion molding technology and the cloud-based precise system for process control, which enables the efficient production of socket-type retractable paper straws. These two core technologies address a suite of problems in traditional paper straws, such as the high scrap rate, the long production cycle, and the poor standard. Moreover, they can be tailored to the required diameter or thickness according to different scenarios.
