label-free array systems market is projected to grow at a CAGR of 6.4% during the forecast period 2021 to 2027. Label-free array systems are the devices that monitors the molecular interactions in an array format. These are used in identification and validation of new molecules. The system offers freedom to choose array format. The label-free array systems are used in the biotechnology and pharmacological industries. Increase in the prevalence of chronic diseases has driven the need for discovery of the drugs to treat ailments. Hence, for the identification or validation of new molecules these systems play a vital role and they also reduce the time and cost of the procedure which is expected to drive the growth of the Label-free Array Systems Market. To avoid dosing redundancy in people, modern medicine is aiming toward precision or individualised medication. Individual diversity in therapeutic effectiveness and a lack of translatability of pre-clinical outcomes are, however, the most significant hurdles in drug research and development. As a result, businesses are concentrating their efforts on building appropriate cellular models and readout technologies in order to better understand processes and functional characterisation at the molecular and cellular levels. Furthermore, next-generation label-free technologies such as mass spectrometers, biochips/microarrays, and others have demonstrated successful identification of clinical microorganisms. Label-free array systems are used in the drug discovery process by biotechnology and pharmaceutical businesses. For finding and validating novel compounds as possible drug candidates, it uses the principles of refractive index, impedance-based tests, and optical interferometry. The systems lower the cost and time it takes to identify and validate drugs.
