In the fast-evolving landscape of biomedical diagnostics, genomics, and life sciences, the need for high-quality glass substrates has become increasingly critical. Whether you’re fabricating biochips, engineering microarrays, or developing microfluidic devices, precision optical glass plays a vital role in ensuring consistent results and reliable performance.

At Lighting,we provide a wide range of specialty glass solutions tailored for biomedical applications. From surface-functionalized slides to low-autofluorescence substrates, our products are engineered for compatibility with DNA sequencing, protein analysis, biosensing, Hydrophilic / Hydrophobic Glass Surfaces,Coated Glass for DNA/RNA Binding,and lab-on-a-chip systems.
Glass Solutions for Biochips and Microarrays
Precision and consistency are essential in the fabrication of biochips, microarrays, and microfluidic systems, where every molecular interaction depends on substrate stability and surface characteristics. Our optical glass substrates are designed specifically for these high-sensitivity applications.

We offer a range of materials including aminosilane-coated, epoxysilane-coated, and low-autofluorescence slides. These products provide controlled surface reactivity, ideal for immobilizing DNA, RNA, peptides, or antibodies with high density and uniformity. The extremely low background fluorescence enables accurate optical detection in fluorescence-based assays.
Our glass is dimensionally stable even under temperature fluctuations, with excellent surface flatness and minimal thickness variation—key features that enhance the accuracy of microarray printing systems, biosensor fabrication, and lab-on-a-chip integration. The chemical resistance of the substrate also ensures compatibility with cleaning and sterilization procedures.
Whether used in high-throughput drug screening or academic biosensor development, our microarray glass ensures optimal reproducibility and performance across multiple assays.
To ensure reliable performance across spotting, imaging, and biosensing workflows, we strictly control the optical and physical characteristics of our biochip substrates. Below are key parameters that make our glass ideal for microarrays and lab-on-a-chip applications:
Parameter | Specification | Importance |
---|---|---|
Optical Transmission | ≥ 90% (400–700 nm) | Supports high-clarity fluorescence and visible imaging |
Surface Roughness (Ra) | ≤ 1 nm | Enables consistent biomolecule immobilization |
Thickness Tolerance | ± 0.05 mm or better | Ensures uniform spotting and scanner focus |
Flatness | ≤ λ/4 per inch | Critical for laser-based printing and imaging alignment |
Autofluorescence | Ultra-low | Reduces background noise for sensitive fluorescence detection |
Coating Types | Aminosilane, Epoxysilane, Hydrophilic | Customized for DNA/RNA/protein microarray compatibility |
Glass for DNA Microarrays and Genomic Sequencing

DNA microarrays and next-generation sequencing (NGS) platforms rely heavily on glass substrates for sample anchoring, hybridization efficiency, and signal fidelity. Poor surface uniformity or non-specific background can significantly compromise data accuracy—especially when dealing with low-abundance gene targets.
To meet these challenges, we provide DNA microarray glass slides with highly controlled surface chemistries, including Aldehyde, Aminosilane (Slide A+), and Epoxysilane (Slide E) coatings. These surfaces allow strong and stable binding of nucleic acids, while minimizing non-specific interactions and signal distortion.
Our substrates are optimized for use in:
- NGS sample prep workflows
- Methylation assays (MeDIP-Seq)
- ChIP-Seq and transcriptomic profiling
- DNA/RNA hybridization protocols
- Whole genome and exome sequencing
The excellent optical clarity and biocompatibility of our slides ensure they integrate seamlessly with fluorescence scanners, thermal cyclers, and liquid handling robots. Moreover, our strict quality control and ISO-grade cleanroom production mean that batch-to-batch consistency is guaranteed—making us a trusted supplier for biotech companies and academic genomics labs alike.
Glass used in DNA and genomic applications must support high binding efficiency, thermal stability, and minimal non-specific interaction. The table below summarizes our substrate performance designed for sequencing and hybridization workflows:
Parameter | Specification | Importance |
---|---|---|
Surface Functionalization | Aldehyde / Aminosilane (Slide A+) / Epoxysilane (Slide E) | Enhances nucleic acid attachment for hybridization and PCR workflows |
Thermal Resistance | ≥ 500°C | Supports denaturation, PCR cycling, and high-temp hybridization |
Biocompatibility | High (non-cytotoxic) | Suitable for cell-based genomic platforms |
Fluorescence Compatibility | Yes (low background, high clarity) | Optimized for laser scanners and NGS readouts |
Sequencing Compatibility | MeDIP-Seq, ChIP-Seq, NGS | Proven in methylation, chromatin, and exome/genome workflows |
Glass for Protein Microarrays and Biomolecular Detection
Protein microarrays require specialized substrates capable of retaining functional biomolecules and maintaining signal stability across multiple detection cycles. At Lighting Glass, we offer advanced coated slides tailored for biomolecular immobilization, antibody binding, and fluorescence or chemiluminescence-based detection.

Our 3D polymer-coated glass (Slide P) and 3D thin film surfaces (Slide H) provide a high-capacity, hydrophilic environment that supports the three-dimensional orientation of proteins—preserving their active sites and enhancing assay sensitivity. Meanwhile, our HiSens reflective optical glass slides increase signal reflection and intensify fluorescence emission, making them ideal for low-abundance targets.
These substrates are commonly used in:
- Antigen-antibody interaction analysis
- Pharmaceutical compound screening
- Biochemical pathway monitoring
- Enzyme-linked detection systems
- Multiplex immunoassays
Their compatibility with well-plate arrays, automated printing machines, and laser-based readout systems ensures smooth integration into both research and diagnostic pipelines. In high-throughput labs where precision matters, our glass helps minimize signal variation and maximize result reproducibility.
Protein assays require substrates that promote biomolecule orientation, preserve structure, and enhance signal detection. Here are the performance benchmarks our protein microarray substrates are built to meet:
Parameter | Specification | Importance |
---|---|---|
Coating Types | 3D Polymer (Slide P), 3D Thin Film (Slide H), HiSens Reflective Coating | Preserves protein activity and enhances binding density |
Signal Enhancement | Reflective Optical Coating (HiSens) | Boosts fluorescence sensitivity for low-abundance targets |
Hydrophilicity | Optimized for spotting & biofunctionality | Supports protein folding and active site exposure |
Compatibility | Well-plate readers, robotic printers | Easy integration with standard assay platforms |
Surface Uniformity | ≤ 1 nm Ra | Ensures reproducible signal and high-resolution detection |
