University of Hong Kong scientists explore growing organs with 3D printing tech
Professor Michael Chan Chi-wai from HKU's Centre for Immunology and Infection said his team was looking to produce personalised 3D-printed airways for burn victims using organoids or 'mini-organs' grown from patients' own cells collected through a single oral swab.
'Airways are one of our strengths and an area we have dedicated significant time to. When people suffer from burn injuries, they may need to reconstruct their airway,' said Chan, who also belongs to the division of public health laboratory sciences at HKU's medical faculty.
'Existing technologies allow the 3D printing of an airway using biomaterials. But without the cells, it cannot perform the functions of an airway.'
Organoids are developed using a person's stem cells and can mimic the function and structure of the actual organs of a specific patient. They can be used to test a certain person's reaction to medicine, vaccines or diseases.
According to Chan, HKU is one of the world's leading institutions in the research and development of respiratory organoids. The university has set up a spin-off company called C2iTech, specialising in personalised organoid cultivation.

Mathematician Zhang Yitang says he left US for China due to political climate
Mathematician Zhang Yitang, who joined Sun Yat-sen University in Guangzhou from California in June, has called the wave of Chinese researchers exiting the US a 'positive trend'. Zhang, known for his prime number research, told Phoenix TV, a partially state-owned broadcaster, in a programme aired on Monday that he had been thinking about returning to the mainland 'in light of recent international political issues that have strained China-US relations'. 'Many Chinese scholars and professors in the US have already returned, and many others are still considering it,' Zhang said. 'I think this is a positive trend.' 'My field is not greatly affected, but for researchers in computers, chips or anything related to the military industry, they need to be especially careful,' he warned. 'The US is very strict about these areas now.' Zhang (left) receives his letter of appointment as a full-time faculty member at Sun Yat-sen University's Institute of Advanced Studies Hong Kong on June 27, 2025.

Knee surgery patients with ‘penicillin allergy' face higher infection risk: study
Patients labelled as allergic to penicillin – usually incorrectly – are three times more likely to develop a serious joint infection after knee surgery as they receive weaker antibiotics, a Hong Kong study has found, with researchers urging them to seek an evaluation especially before their operation. A team from the University of Hong Kong, which released the findings of the study on Wednesday, said that about 90 per cent of patients recorded as being allergic to the commonly used antibiotic were wrongly labelled. 'We found that if patients are wrongly labelled as allergic to penicillin, there can be a very serious consequence, which is infection,' said study co-leader Dr Steve Cheung Man-hong, an honorary clinical assistant professor in the department of orthopaedics and traumatology at HKU. 'There should be appropriate and timely evaluation on allergy labels.' The study analysed 4,730 patients who had undergone knee replacement surgery at Queen Mary Hospital in Pok Fu Lam between 1993 and 2001. Among them, 165 were labelled allergic to penicillin, the most common and first-line antibiotic used by doctors before joint surgery to prevent infections.
