CD BioSciences has developed a variety of optical-based, real-time biophysical assays to provide our clients with tumour cell detection services, including differentiating tumour cells from normal cells and detecting and quantifying tumour biomarkers. We are committed to providing scientific services and technical support for basic research and preclinical drug development.
Cancer is the collective name for a large group of malignant tumours and is the second leading cause of death worldwide after cardiovascular disease. Early diagnosis of cancer is important to reduce morbidity and mortality as well as to alleviate the suffering and emotional and financial burden on patients. A variety of optical-based methods have been used to identify, detect, classify and quantify tumour cells. These have the advantage of being non-invasive, rapid, accurate and with high spatial resolution compared to conventional methods.

Traditional methods used to identify tumour cells from normal cells are often slow, non-specific and biologically intrusive. The introduction of Raman spectroscopy in tumour identification avoids these drawbacks and provides rich information on the molecular structure and composition of the material in a non-invasive form, reflecting the structural differences between cancerous and normal tissue at the molecular level. We have established various techniques such as micro Raman spectroscopy and laser tweezer Raman spectroscopy (LTRS) to provide tumour cell detection for our clients.
Tumour cells produce and release certain substances, often in the form of antigens, enzymes, hormones and other metabolites, either within the tumour cells or in the host body fluid. Biomarker detection is a proven method to provide accurate biological information to identify or diagnose tumours. We have developed a variety of biophysical techniques to detect and quantify cancer biomarkers through liquid biopsies to detect disease progression. We offer the following detection services:
The technologies we offer include but are not limited to:
