The global quantum dot sensors market is expected to grow at a CAGR of around 11.3% from 2020 to 2027 and expected to reach the market value of around US$ 196.5 Mn by 2027.

When a blue LED is pumped, quantum dots emit light of a specific wavelength, and the wavelength of the light depends on the size of the Quantum Dots. A quantum dot sensor employs quantum dot technology with an integration method, resulting in image capture accuracy. The quantum dot sensor is used in biological applications such as cellular imaging, real-time tracking of cells and molecules, tumor detection, and cell component observation. Because of their unique electronic properties, quantum dots are used as active materials in single-electron transistors. A quantum dot sensor employs materials that use quantum dot technology and a simple method of integration, allowing for the occupancy of approximately 95% of an image. Depending on the particle size of the quantum dot, QDs have broad absorption spectra with wavelengths ranging from ultraviolet to visible.

Growth Factors

The growing demand for improved sensor technologies, as well as increased awareness of energy-efficient solutions, has accelerated the adoption of quantum dot products. Numerous advantages of quantum dot technology include energy efficiency, ultra-high definition, low cost, and high brightness. It is difficult to use silicon-based sensors in the production of next-generation image sensors. The new sensors employ quantum dot technology and a straightforward integration method to capture the maximum portion of an image with extremely high quality. In addition, quantum films are the camera platform of the future. The growing use of quantum films in mobile phones, cameras, and other applications has increased demand for small-sized, high-performance image sensors. The high cost of technology and the slow adoption of this technology due to extensive research are the key factors that can act as a restraint in the market for quantum dots. Growing adoption of this technology in new applications such as food and packaging, security and defense, and others will create new market opportunities in the coming years.

What's new in QD based sensors market?

Quantum dot sensor have gained huge prominence in the research and development

Transition metal ions are vital natural elements that play critical roles in a wide range of biological processes. An excess of these ions, on the other hand, is harmful. As a result, PL sensors based on transition metal ions have been actively developed. The use of QDs to detect biomolecules such as DNA, proteins, and saccharide has been a focus of recent research. The most commonly used tactic for sensor construction is replacement assay. Bio-functionalized QDs have been used for cellular imaging by taking advantage of their superior optical properties such as high signal brightness and photo stability. QD decorated with a targeting agent capable of facilitating QD uptake by specific cells and/or with a reactive site capable of interacting with a defined intracellular species have been extensively prepared for “target-specific” imaging of live cells. Although there are still arguments against using QDs in vivo to supplement current clinical contrast agents, efforts to evaluate the imaging ability of QDs with animal models have been extensive. Aside from the traditional use of QDs as chemo- and biosensors, some new trends in their use are noteworthy. The synthesis of QDs by living organisms is of great interest. QDs have been used in the development of diagnostic tools due to their photophysical advantages. QDs, in particular, have been used as organic dye surrogates in immunoassays for disease marker detection.

Market Trend

High demand for quantum dot sensors for biomedical and environmental applications

QDs' high luminescence, narrow emission, and (depending on elemental composition) low toxicity and biocompatibility make them an ideal candidate for bioimaging, diagnostics, and bio sensing applications, primarily in biomedical and environmental sciences. Following interaction with BSA, bioimaging and biosensing were demonstrated for QD complexes composed of zinc chalcogenide QDs such as undoped and Mn2+-doped ZnS and surface zinc quinolate (ZnQ2) complexes. Furthermore, QDs were used as a thermometer over a wide, biologically relevant temperature range.

Market Challenges

Cost-effective manufacturing methods are expected to reduce the cost of competitive technologies such as OLED, LCD backlight, and LED. Prices for quantum dot hardware are expected to fall in the coming years. The price of small quantum dots display substrates is expected to fall as well; however, this drop is likely to be offset in the long run by an increase in substrate size, which would be more expensive than existing panels. As a result, in order to compete effectively with LCDs, quantum dot display prices must be reduced. A drop in the prices of competing technologies can have a significant impact on quantum dot-based displays in the short and long term.
