5 wt. % nanodiamond 2‐Butoxyethanol colloid; additive to inks, paints, varnishes, herbicides, enamels, defoamers, glues, etc.Highly dispersed &Stable; Average grain size: 3.5-6.0 nm, high photoluminiscence
In the frame of this project RAY has developed special techniques for nanodiamonds surface modification enabling high photo-luminescence (PL). These bright nanodiamonds with the average size of 5 nm are studied as efficient multi-modal bio-imaging agents for luminescence, photo-induced electrical and acoustic techniques for their localization in living cells. Moreover, photo-exciting properties used for the bio-imaging purpose are applied for therapy of cancer cells and tissues. Fig.1. PL map of RAY nanodiamonds. Fig. 2. RAY nanodiamonds demonstrate high efficiency in cell imaging. Fig. 3. Specially modified RAY nanodiamonds in the concentration of 1 mg/ml "kill" cancer cells (Panc01) almost not affecting the healthy tissue (3T3-L1). Panc01 control and 3T3-L1 control graphs were obtained without nanodiamonds in the added solution. Cell index indicates that, in contrast to Panc01 control, Panc01 treated with 1mg/mL nanodiamonds stopped multiplying, while 3T3-L1 cells with and without nanodiamonds behave similar. This fact confirmed using various cancer and non-cancer cell lines opens prospect of use nanodiamonds as non-toxic therapeutic agent.

Diamond is absolutely dielectric and has the highest thermal conductivity observed; this combination is unique and not found in any other material in nature. Therefore, nanodiamonds having the same properties, is an especially promising component in solving the problem of overheat of active elements in microelectronics. Used as a dielectric diathermic filler, nanodiamonds efficiently enhance material's ability to dissipate heat. Consequently, using nanodiamonds in pastes, glues and substrates provides an unprecedented opportunity of avoiding burnout and increasing speed of active elements, as well as reducing the size of devices and increasing their reliability and durability. Insufficient thermal conductivity of existing isolating materials limits further size reduction and frequency increase of active elements in microelectronics, as well as their reliability. Using nanodiamonds as a filler improving heat dissipation in the electronic industry should solve the most painful problem, overheating of active elements. Ray nanodiamonds being metal free, much purer and more homogeneous have significant advantages for heat dissipators in comparison with detonation nanodiamonds existing today in the market. Numerous applications include: - Thermo-conductive greases - Die attach adhesives - Heat spreaders for high-power laser diodes - Compounds for PCB fabrication - Submounts for integrated circuits - Substrate material for multi-chip modules Currently nanodiamonds are making a breakthrough into high power electronics.

RAY offers nanodiamond additives of high and constant quality for various products and processes. RAY's additives are in the form of functionalized powders, slurries in various solvents and customized masterbatches based on diverse polymers. RAY's additives do not require additional developments for their mixing with other materials. Nanodiamonds consist of diamond grain in the core (usually 4 nm in average) and hybrid graphene-like structure with various functional groups on the surface. Controlled interaction between functional groups and other molecules enable to bond them with diamond nano-crystallites, "to transfer" them unique features of diamond and to create new materials and objects with improved properties.
