What Are 100 nm NV Center Nanodiamonds?
Nanodiamonds embedded with nitrogen-vacancy (NV) centers have become a critical material for researchers and engineers who need quantum-level sensitivity in extremely small form factors. Among the various particle sizes available, 100 nm NV center nanodiamonds occupy a unique position: they are large enough to host multiple NV centers for stable signal generation, yet small enough to be used in intracellular environments, thin-film coatings, and miniaturized sensing devices. ViQium Technologies Co., Ltd., operating under the brand name ViQium, has developed a dedicated Nano-NV Diamond product line that includes 100 nm particles as part of its broader Micro-nano NV Diamond series, giving customers a scalable, customizable option for advanced quantum sensing work.
The Science Behind NV Center Nanodiamonds
To understand why 100 nm NV nanodiamonds are valuable, it helps to look at how the underlying technology works. ViQium's core technology is based on nitrogen-vacancy (NV) centers, a quantum defect embedded within the diamond lattice that functions as an extremely small quantum sensor. The operating principle consists of three steps: optical initialization, where a green laser prepares the NV center's quantum state; quantum manipulation, where a precisely tuned microwave field adjusts the spin state; and optical readout, where red fluorescence is analyzed to extract information about the surrounding physical environment.
A key advantage of NV centers is their room-temperature operation capability combined with nanoscale sensing resolution. This combination makes NV-based nanodiamonds particularly suitable for applications requiring flexible operating environments and extremely high spatial resolution—precisely the conditions found in biological imaging and compact sensor design, where 100 nm particles are frequently deployed.
ViQium's Nano-NV Diamond Product Line
Within its Micro-nano NV Diamond category, ViQium offers Nano-NV Diamond products with an NV Density of 0.2–3 ppm and particle sizes of 30 nm, 50 nm, and 100 nm. The specific product codes covering these sizes include NDP-NV-01-30 (1 ppm, 30 nm), NDP-NV-01-50 (1 ppm, 50 nm), and NDP-NV-03-100 (3 ppm, 100 nm). This structured product coding allows customers to identify the exact NV density and particle size combination needed for their experiments without ambiguity.
These nanodiamonds are described as well suited for super-resolution bioimaging and cell tracking, intracellular quantum sensing, miniaturized magnetometers and thermometers, as well as information security and anti-counterfeiting applications. The 100 nm size in particular offers a practical balance between signal strength, from a higher 3 ppm NV density, and the small footprint required for cellular-scale or device-integrated sensing tasks.
Customization Capabilities for 100 nm NV Diamonds
A defining feature of ViQium's offering is its customer service commitment: product customization alongside factory calibration and characterization data. Rather than limiting customers to fixed specifications, ViQium supports tailored requests for NV concentration and particle dimensions within its nanodiamond platform. This flexibility extends from ViQium's broader manufacturing philosophy, where the company provides "a comprehensive product portfolio covering (111)-oriented high-density and ultra-high-density NV diamonds, shallow NV diamonds, nanodiamond powders, C12-enriched diamond materials, and single NV center diamonds," with support for customized specifications including diamond dimensions and NV center concentration.
On delivery timing, ViQium states that standard products can be delivered within 28 days, while conventional customized products can be delivered within 45 days, giving customers a clear expectation for planning research or production schedules around custom 100 nm NV nanodiamond orders.
Manufacturing Advantages Behind the Product
ViQium has independently established a complete production process covering diamond crystal growth, ion irradiation, and high-temperature annealing. This integrated process supports the company's ability to produce NV center diamond materials across a range of densities and formats, including the nano-scale particles used in the 100 nm product line. The company notes that its products achieve high ODMR contrast performance, with key parameters positioned to be comparable to established international supplier product series, while also supporting flexible customization starting from a single piece.
This approach addresses a documented industry gap: many suppliers offering small-batch customization still show gaps in key material parameters such as NV center concentration, uniformity, and coherence time. ViQium's stated response is to combine flexible small-batch customization with advanced in-house fabrication capabilities, allowing parameters such as crystal orientation, NV concentration, sample dimensions, and microstructure processing to be tailored to specific requirements.

Applications Across Research and Industry
The target use cases for 100 nm NV nanodiamonds span both academic and applied settings. For research institutes and universities, the core need is high-quality, reproducible quantum materials that support fundamental physics validation, with emphasis on technical performance, pricing, delivery timelines, and technical support. For advanced industrial inspection and precision manufacturing companies, the priority shifts toward system integration, long-term operational reliability, and scalable supply capacity, moving beyond conventional measurement toward high-sensitivity, non-invasive, real-time sensing.
Addressing Common Customer Challenges
ViQium's documented customer support approach responds directly to challenges frequently encountered when selecting NV diamond materials. One challenge is the lack of clear selection criteria for first-time users, who often struggle to determine optimal crystal orientation and NV center concentration for their specific experiments. ViQium's response is a comprehensive NV Diamond Selection Guide paired with professional online consultation, with products categorized by application requirements such as magnetic field sensing, magnetic imaging, and temperature sensing.
A second challenge involves limited access to small-batch customization combined with high-performance material specifications. ViQium addresses this by combining flexible small-batch customization with in-house fabrication, aiming to deliver comparable performance to high-end products with more competitive pricing and shorter delivery cycles for customized orders.
