Microfluidic Chips and Organ-on-a-Chip

Matexcel is a high-tech company specializing in the research, development, and supply of microfluidic chips and organ-on-a-chip products. By integrating traditional laboratory instruments onto chips measuring just a few square centimeters, microfluidic chip technology enables the miniaturization and micro-scale implementation of systems, demonstrating significant application value in fields such as cell analysis, gene sequencing, and drug screening.

What are Microfluidic Chips?

Microfluidic chips, also known as lab-on-a-chip devices, are an interdisciplinary technology that integrates microelectromechanical systems (MEMS), fluid mechanics, biology, chemistry, materials science, and other fields. Through precision fabrication, it creates micrometer-scale structures such as microchannels, microvalves, micropumps, and micro-reaction chambers on substrates like glass, PDMS, and PMMA. This enables precise control of the transport, mixing, reaction, sorting, cultivation, and detection of liquids, cells, and reagents—ranging from nanoliters to microliters—within the chip.

Our core product—the organ-on-a-chip—is an in vitro organ simulation system built on microfluidic technology. It features high bionic similarity and controllability, enabling precise simulation of human organ microstructures, microenvironments, and metabolic activities. Compared to traditional 2D cell culture models, this technology represents a qualitative leap in terms of physiological microstructure and functional integrity, providing an efficient and reliable alternative to animal testing for drug development and toxicity assessment.

Key Applications of Microfluidic Chips and Organ-on-a-Chip

Drug Screening and Efficacy Evaluation: Utilizing organ-on-a-chip technology to simulate the human physiological environment, enabling high-throughput testing of drug candidates to evaluate efficacy and toxicity, thereby reducing the risk of clinical trial failure.
Disease Modeling: Developing organ-on-a-chip models for organs such as the tumor, liver, and lung to simulate pathological conditions (e.g., cancer metastasis, fibrosis) for mechanistic research and the discovery of new therapeutic targets.
Personalized Medicine: Combining patient cells to construct customized organ-on-a-chip models to test different drug regimens and provide precise medication guidance for individuals.
Toxicity Prediction and Safety Assessment: Real-time monitoring of damage responses to drugs or chemicals in organ-on-a-chip models of the liver, heart, kidneys, and other organs, replacing some animal testing and improving predictive accuracy.
Basic Biological Research: Controlling the cellular microenvironment (e.g., fluid shear stress, concentration gradients) on microfluidic chips to study cell migration, differentiation, and cell-cell interactions.

2. Select Based on Material Properties

Material	Advantages	Limitations	Applications
PDMS (Polydimethylsiloxane)	High gas permeability, excellent elasticity, good biocompatibility, easy prototyping.	Inherent hydrophobicity (surface treatment required), low pressure resistance, difficult for large-scale production.	Academic research, cell culture, organ-on-a-chip.
Glass	High transparency, chemical inertness, high pressure resistance, superior optical performance.	Fragile, high processing cost.	Optical detection, high-pressure applications.
Thermoplastics (PMMA/COC/PC)	Cost-effective, low autofluorescence, suitable for mass production.	Poor gas permeability.	High-throughput screening, industrial applications.
Hydrogel	Mimics the extracellular matrix, supports 3D cell culture.	Low mechanical strength.	Vascularized tissue engineering, organoid culture.
Silicon	Outstanding chemical stability, high thermal conductivity, and high machining precision.	Opaque, highly brittle.	Special chemical processes.

3. Select Based on Structural Parameters

Parameter	Typical Range	Selection Recommendations
Channel Width	5-500 μm	Wider channels for cell research to prevent clogging; narrow channels for droplet generation.
Channel Depth	10-200 μm	Deeper channels bring lower flow resistance, yet may reduce cell adhesion efficiency.
Culture Chamber Volume	5-10 μL (high-throughput) to tens of microliters (research grade).	Choose small-volume chambers for rare samples.
Sealing Performance	No leakage under 0.2 MPa pressure holding for 30 minutes.	Mandatory for dynamic cell culture.
