Overview
Microfluidics, often referred to as "lab-on-a-chip," involves the manipulation of fluids in channels with dimensions typically from tens to hundreds of micrometers. When magnetic beads are introduced into these channels, they can be precisely moved, mixed, and separated using external magnetic fields. This enables a wide array of applications, including:
- Automated Sample Preparation: Magnetic beads can perform sequential steps like cell lysis, nucleic acid extraction, and purification on a single chip, eliminating manual pipetting and reducing contamination.
- Target Enrichment: By conjugating magnetic beads with specific ligands, we can efficiently capture and concentrate low-abundance target molecules from a large volume of sample.
- Multiplexed Assays: Different sets of magnetic beads, each with a unique surface chemistry, can be used to perform multiple assays simultaneously on a single microfluidic chip.
Our service leverages advanced chip fabrication techniques and highly responsive magnetic bead formulations to ensure optimal performance. We understand that every application is unique, and our team works closely with you to design and implement a microfluidic solution that is perfectly tailored to your specific needs.
Our Services
We offer a flexible suite of services that can be used individually or as a complete, integrated solution.
Custom Microfluidic Chip Design and Fabrication
The heart of any microfluidic system is the chip itself. We provide custom design services to create a chip layout optimized for your specific application. Our experts consider factors such as flow dynamics, magnetic field integration, and assay requirements to design a chip that delivers maximum performance. We use a variety of materials, including PDMS, glass, and polymers, and offer both rapid prototyping and large-scale manufacturing.
Magnetic Bead and Reagent Integration
A well-designed chip is only as good as the reagents that run through it. We specialize in integrating our proprietary high-performance magnetic beads and other reagents into microfluidic systems. We develop optimized protocols for bead loading, fluid handling, and magnetic separation to ensure seamless operation on your chip. This service includes selecting the appropriate bead type (e.g., high-affinity, low non-specific binding) and preparing them for microfluidic use.
Assay Development and Automation
Moving a complex assay onto a microfluidic platform requires specialized expertise. Our team can help you transition your manual assay to a fully automated, magnetic bead-based microfluidic workflow. This includes:
- Protocol Optimization: We fine-tune steps such as incubation times, wash volumes, and magnetic separation parameters to ensure high efficiency and reproducibility on the chip.
- Automation Programming: We can program fluidic handling and magnetic control systems to perform your assay with minimal user intervention, reducing errors and increasing throughput.
- Validation: We provide a comprehensive validation report to demonstrate the performance of the automated assay, including sensitivity, specificity, and reproducibility data.
Single-Cell and Rare Cell Isolation
Magnetic bead microfluidics is a powerful tool for isolating rare cell populations or performing single-cell analysis. Our services enable the gentle and efficient capture of specific cells from complex biological samples like blood. This is crucial for applications in cancer research, immunology, and stem cell biology, where a single cell can hold critical information.
Applications
Our services enable transformative advancements across numerous fields:
- Point-of-Care Diagnostics: Develop compact, automated platforms for rapid nucleic acid extraction, immunoassay detection, or pathogen isolation from minimal sample volumes (e.g., blood, saliva).
- Single-Cell Analysis: Achieve high-precision sorting, lysis, and analysis of individual cells using magnetic bead-based capture and barcoding in microfluidic droplets.
- High-Throughput Screening: Implement bead-based assays in microfluidic arrays for drug discovery, antibody screening, or synthetic biology with massively parallel processing.
- Liquid Biopsy and Rare Cell Isolation: Capture circulating tumor cells (CTCs) or exosomes with high purity and viability from complex biological samples.
- Synthetic Biology and Microreactors: Utilize bead-immobilized enzymes or DNA in microfluidic channels for controlled synthesis, PCR amplification, or gene assembly.
- Environmental Monitoring: Create portable systems for on-site detection of contaminants or pathogens in water samples using concentrated magnetic bead capture.
