About PNA Microarrays

Development of PNA Microarrays Biosensors

The PNA microarray biosensor, or PNA biochip, is an analytical device based on covalently immobilizing thousands of PNA probes on a solid substrate. The PNA probes are arranged in a miniaturized two-dimensional dot array, the sample is hybridized with the microarray, and the specific target-probe interaction is detected by a high-resolution scanner. Compared with DNA, the improved stability of PNA and its unique hybridization characteristics provide the possibility of label-free and high-throughput analysis, significantly improving the speed and performance of molecular biology experiments.

Our Services

We provide a wide range of PNA microarray development for research, diagnostics and many other life science applications, as well as detection applications for a wide range of fields such as life sciences and environmental and food analysis. The main services of solutions include but are not limited to the following.

  • Custom PNA microarray

    We design PNA probes that are shorter than equivalent DNA or RNA probes. PNA probe molecules can be synthesized separately through standard peptide synthesis procedures in advance or high-density PNA library arrays can be synthesized in situ by using photolithography on a porous support medium.

  • Immobilize on solid substrate

    We prepare a readable substrate that provides a strong bond between the probe and its addressing site. The main substrate materials include glass, plastic, membranes, microtiter plates, conductors, etc. We treat the surface and select a coupling agent to covalently attach the array and functionalize surface.

  • Detect PNA microarray

    We benchmark various contact and non-contact spotters to select the ideal system. Perform customer specific microarray experiments, evaluations, and records, and compare the results obtained with PNA-based arrays and DNA microarrays. Improve the specificity and stability of the product by measuring and optimizing the experiment.
