Binary Research Group

Dr. Chen received his Ph.D. from the University of Maryland, USA in 1998. The BINARY lab (Biology, Information science and Nanotechnology Applications and Research laboratorY) was founded in Spring 2003. The mission is to provide a cross-disciplinary research environment for exploring new nanoscale device & circuit designs and nanotechnology for bio-medical applications. Our primary research focuses include:

  1. Developing a pulsed-wave technology platform to stimulate cell growth (with the applications in cell therapy, tissue engineering, mental health and antibody productions), and microorganism growth (with the applications in increasing renewable biofuel /algal oil, antibiotics, omega-3, and wine/beverage productions);
  2. Building functional nanomaterials for water filtration (removing microorganisms, organic chemicals and heavy metals), gene transformation of agricultural products, targeted cancer imaging and treatment, gene/peptide/microRNA delivery (especially across the blood-brain-barrier);
  3. Designing portable impedance-based point-of-care devices for detecting metabolic biomarkers, monitoring environmental toxins, sensing plant infections at an earlier stage, and screening pathogens for food safety.
  4. Developing smart-phone Apps incorporating artificial intelligence methods to diagnose depression, especially postpartum syndrome, and invoke clinical intervention if needed. Making low-intensity pulsed ultrasound wearable devices for treatment.

The University of Alberta is home to cutting edge facilities such as the National Institute for Nanotechnology, as well as having the interdisciplinary expertise to be an epicentre for new waves of innovation in Biomedical Engineering. The University of Alberta was ranked 46th in the world for the impact of its engineering publications.


"Classification of cannabis strains in the Canadian market with discriminant analysis of principle components using genome-wide single nucleotide polymorphisms" was accepted    (06/06/2021)

"Classification of cannabis strains in the Canadian market with discriminant analysis of principle components using genome-wide single nucleotide polymorphisms" by Dan Jin, Philippe Henry, Jacqueline Shan, Jie Chen was accepted by PLOS ONE AbstractThe cannabis community typically uses the terms "Sativa" and "Indica" to characterize drug strains with high tetrahydrocannabinol (THC) levels. Due to large scale, extensive, and unrecorded hybridization in the past 40 years, this vernacular naming convention has become unreliable and inadequate for identifying or selecting strains for clinical research and medicinal production. Additionally, cannabidiol (CBD) dominant strains and balanced strains (or intermediate strains, which have intermediate levels of THC and CBD), are not included in the current classification studies despite the increasing research interest in the therapeutic potential of CBD. This paper is the first in a series of studies proposing that a new classification system be established based on genome-wide variation and supplemented by data on secondary metabolites and morphological characteristics. This study performed a whole-genome sequencing of 23 cannabis strains marketed in Canada, aligned sequences to a reference genome, and, after filtering for minor allele frequency of 10%, identified 137,858 single nucleotide polymorphisms (SNPs). Discriminant analysis of principal components (DAPC) was applied to these SNPs and further identified 344 structural SNPs, wh [ ... ]

"High-resolution Metabolomic Biomarkers for Lung Cancer Diagnosis and Prognosis" was accepted    (06/06/2021)

"High-resolution Metabolomic Biomarkers for Lung Cancer Diagnosis and Prognosis" by Shi-ang Qi, Qian Wu, Zhenpu Chen, Wei Zhang1, Yongchun Zhou, Kaining Mao, Jia Li, Yuanyuan Li, Jie Chen, Youguang Huang, Yunchao Huang was accepted by Scientific Reports. Abstract Lung cancer is the leading cause of human cancer mortality due to the lack of early diagnosis technology. The low-dose computed tomography scan (LDCT) is one of the main techniques to screen cancers. However, LDCT still has a risk of radiation exposure and it is not suitable for the general public. In this study, plasma metabolic profiles of lung cancer were performed using a comprehensive metabolomic method with different liquid chromatography methods coupled with a Q-Exactive high-resolution mass spectrometer. Metabolites with different polarities (amino acids, fatty acids, and acylcarnitines) can be detected and identified as differential metabolites of lung cancer in small volumes of plasma. Logistic regression models were further developed to identify cancer stages and types using those significant biomarkers. Using the Variable Importance in Projection (VIP) and the area under the curve (AUC) scores, we have successfully identified the top 5, 10, and 20 metabolites that can be used to differentiate lung cancer stages and types. The discrimination accuracy and AUC score can be as high as 0.829 and 0.869 using the five most significant metabolites. This study demonstrated that using 5+ metabolites (Palmitic aci [ ... ]

"Exploratory Study on Neurochemical Effects of Low Intensity Pulsed Ultrasound in Brains of Mice" was accepted    (13/03/2021)

"Exploratory Study on Neurochemical Effects of Low-Intensity Pulsed Ultrasound in Brains of Mice" was accepted for publication Abstract Background. There is now a relatively large body of evidence suggesting a relationship between dysfunction of myelin and oligodendrocytes and the etiology of several neuropsychiatric disorders, including depression and schizophrenia, and also suggesting that ultrasound methods may alleviate some of the symptoms of depression. Methods. We have applied low-intensity pulsed ultrasound (LIPUS) to the brains of mice treated with the demyelinating drug cuprizone, a drug that has been used as the basis for a rodent model relevant to a number of psychiatric and neurologic disorders including depression, schizophrenia, and multiple sclerosis. Prior to conducting the studies in mice, preliminary studies were carried out on the effects of LIPUS in vitro in neuron-like SH-SY5Y cells and primary glial cells. In subsequent studies in mice, female C57BL/6 mice were restrained in plastic tubes for 20 minutes daily with the ultrasound transducer near the end of the tube directly above the mouse's head. LIPUS was used at an intensity of 25mW/cm2 once daily for 22 days in control mice and in mice undergoing daily repetitive restraint stress (RRS). Behavioral or neurochemical studies were done on the mice or the brain tissue obtained from them. Results. The studies in vitro indicated that LIPUS stimulation at an intensity of 15 mW/cm2 delivered for 5 min daily [ ... ]

"Identification of phenotypic characteristics in three chemotype categories in the genus Cannabis" was accepted by Hortscience    (15/02/2021)

"Identification of phenotypic characteristics in three chemotype categories in the genus Cannabis" was accepted by Hortscience Abstract: Modern Cannabis cultivars are morphologically distinguished by their leaflet shapes (wide for “Indica” and narrow for “Sativa”) by users and breeders. However, there are no scientific bases or references for determining the shape of these leaflets. In addition, these two categories contained mostly THC dominant (high THC) cultivars while excluded CBD dominant (high CBD) and intermediate (intermediate level of both THC and CBD) cultivars. This study investigated the phenotypic variation in 21 Cannabis cultivars covering three chemical phenotypes, referred to as chemotypes, grown in a commercial greenhouse. Thirty morphological traits were measured in the vegetative, flowering, and harvest stages on live plants and harvested inflorescences. The collected data were subjected to correlation analysis, hierarchical clustering, principal component analysis, and canonical correlation analysis with preassigned chemotypes. Canonical correlation analysis assigned individual plants to their chemotypes with 92.9% accuracy. Significant morphological differences were identified. Traits usable as phenotype markers for CBD dominant cultivars included light-green and narrow leaflets, a greater number of primary and secondary serrations, loose inflorescences, dense and resinous trichomes, and Botrytis cinerea resistance. Traits for intermediate culti [ ... ]
