Biotemplated nanomaterials offer versatile functionality for multimodal imaging, biosensing, and drug delivery. There remains an unmet need for traceable and biocompatible nanomaterials that can be synthesized in a precisely controllable manner. Here, we report self-assembled quantum dot DNA hydrogels that exhibit both size and spectral tunability. We successfully incorporate DNA-templated quantum dots with high quantum yield, long-term photostability, and low cytotoxicity into a hydrogel network in a single step. By leveraging DNA-guided interactions we introduce multifunctionality for a variety of applications, including enzyme-responsive drug delivery and cell-specific targeting. We report that quantum dot DNA hydrogels can be used for delivery of doxorubicin, an anticancer drug, to increase potency 9-fold against cancer cells. This approach also demonstrated high biocompatibility, trackability and in vivo therapeutic efficacy in mice bearing xenografted breast cancer tumors. This work paves the way for the development of new tunable biotemplated nanomaterials with multiple synergistic functionalities for biomedical applications.

Quantum Dot Enhancement Film (QDEF)
See also: Quantum dot display
Nanosys Quantum Dot Enhancement Film, or QDEF, is an optical film component for LED driven LCDs. Each sheet of QDEF contains trillions of tiny Quantum Dot Phosphors. QDEF enables LED-backlit LCDs to be brighter and more colorful by providing a high quality, tri-color white light from a standard blue LED light source. Larger than a water molecule, but smaller than a virus, these tiny phosphors convert blue light from a standard Gallium Nitride (GaN) LED into different wavelengths based upon their size. Larger dots emit longer wavelengths (red), while smaller dots emit shorter wavelengths (green). Blending together a mix of dot colors allows Nanosys to precisely engineer a new spectrum of light to customer specifications.[2]
The Quantum Dots are tuned to create better color by changing their size during fabrication to emit light at just the right wavelengths. Traditional light emitting materials such as crystal phosphors have a broad fixed spectrum. Quantum dots can convert light to nearly any color in the visible spectrum, giving display designers the ability to tune and match the spectrum more accurately to color filters while improving energy efficiency.
QDEF was announced on May 17, 2011 at the Society for Information Display (SID) Display Week tradeshow.[3][4] It has been adopted in products such as the Amazon Kindle Fire HDX 7 (2013)[5] and the ASUS Zenbook NX-500 (2014).[6]
At the Consumer Electronics Show 2015 it became known that Nanosys has licensed Samsung Electronics as well as 3M to manufacture QDEF products. QDEFs from 3M are used by top US TV brand Vizio (M-Series Quantum, P-Series Quantum & P-Series Quantum X) as well as TV manufacturers Hisense (ULED TV) and TCL (QLED TV) TV sets.[7]
In 2020, Nanosys announced a supply agreement with Shoei Chemical, a Japan-based producer of nanoparticles, under which the latter became the sole manufacturing partner of QD materials.[8]
