Dr Chang Lei

Dr Lei is an ARC Discovery Early Career Researcher Award (DECRA) fellow and a trained dentist with expertise in nanotechnology-based bioanalysis, mass spectrometry, lateral flow immunoassay, and tissue regeneration. She completed her PhD at the Australian Institute for Bioengineering and Nanotechnology (AIBN) at The University of Queensland (UQ). Shortly after her PhD, she received the Queensland Government Advance Queensland Research Fellowship to support her research on nanotechnology-enhanced bio-detection with an industry translational focus. She was then awarded the UQ Amplify Fellowship in 2021 and secured the prestigious ARC DECRA in 2024.

Dr Lei has authored 40 publications with an h-index of 21, including articles in prestigious journals such as Natl. Sci. Rev, Small, Biosens Bioelectron, Angew. Chem and Adv. Mater. Additionally, she holds two patents and has secured over $1.13 million in research funding. Dr Lei is a reviewer for scientific journals such as Sci Adv, Journal of Nanobiotechnology, J. Mater. Chem. B., and for ARC and NHMRC grants. She also serves as an editor for Frontiers in Bioengineering and Biotechnology and Nano TransMed.

Next Generation Mass Spectrometry for Single-Cell Metabolomics

Characterising metabolites at the single-cell level will provide valuable insights into the functionality of individual cells and reveal mechanisms that cannot be observed in bulk cell analysis. Mass spectrometry (MS) is a sensitive analytical technique that can measure chemical compounds and biological molecules, and it is widely used in diverse applications including biological research, drug testing, food contamination detection, and pesticide residue analysis. This project will develop a novel platform equipped with innovative nanomaterials featuring carefully designed nanostructures to enhance the sensitivity of MS, enabling high-quality single-cell metabolomics analysis.

A Nano-platform for Affordable and Ultra-sensitive Biomarker Detection

Biomolecules of clinical significance are often various forms of proteins or peptides present at very low concentrations in biological systems. Analysing these biomolecules is a significant challenge due to the complexity of bio-samples, yet it is essential for diagnosis and clinical applications. In this project, we focus on developing novel approaches for the sensitive detection of trace biomolecules using state-of-the-art nanotechnology. The project involves the preparation and characterisation of porous nanomaterials, biomolecule detection, and disease diagnosis.

Silica bio-nanomaterials assisted stem cell differentiation for bone repair

Bone defects, caused by infections, tumours, traumas, or congenial deformity, usually needs surgical interference and to be repaired with bone grafts or biomaterials. The traditional bone repair strategies usually have slow regeneration rate due to the poor cell adhesion and poor differentiation induction capacity of bone repair materials. This project aims to develop novel biomaterials to promote the differentiation of bone marrow stem cell for bone regeneration. Nanomaterials with functional compositions and porous nanostructures will be fabricated. Their cellular internalisation process and the resulted bone regeneration efficiency will be evaluated. On completion of this project, a next generation of biomaterial with high bone repair efficiency will be developed and the in-depth understanding on the interaction between nanomaterial and stem cell differentiation will be revealed.
