Summary: This study presents a biomimetic crystallization-empowered self-assembly method for a tumor-targetable DNA-inorganic hybrid nanocomposite aptasensor, enabling quantitative interpretation of changes in cellular target abundance using Forster resonance energy transfer (FRET). Leveraging the design programmability and high-throughput fabrication of rolling circle amplification-driven DNA nanoarchitecture, this platform offers a method to self-assemble a robust nanosensor from a multifunctionality-encoded template including a cell-targeting aptamer, a ratiometric aptasensor, and a cholesterol-decorating element.

Summary: Tunable full-color luminescence is achieved by mixing rare-earth-doped SrAl2O4: Eu2+, Dy3+ (green emission), Y2O2S: Eu3+, Mg2+, Ti4+, Ti4+ 0.05 (red emission), and Sr2MgSi2O7: Eu2+, Dy3+ (blue emission) phosphors with different ratios. The phosphors exhibit white light and full-spectra emission under low excitation energy. The strategy enables enhanced encryption capacity of luminescent unit-based 3D codes with infinite emission colors.

Summary: ATP has been used as an anionic biocomponent in the design of dynamic and stimuli-responsive supramolecular assemblies. By enhancing Fo''rster resonance energy transfer (FRET), tunable multiluminescent materials can be generated in aqueous solutions, polymer, and solid films. The emission covering a wide range of visible spectrum and the FRET ON/OFF features controlled by various stimuli make it suitable for encryption-decryption applications.

Summary: HIV-1 infectivity relies on virion maturation, with most proviruses in individuals on antiretroviral therapy having large deletions but preserving the ability to express viral structural proteins. A novel single-virion visualization technique using fluorescence resonance energy transfer allowed for the distinction between mature and immature virions based on their FRET signal. This tool can be used to assess maturation efficiency and understand the impact on immune responses of intact and defective viruses.

Summary: This research proposes a strategy to achieve tunable and water-processable room temperature afterglow (RTA) from carbon dots (CDs). By mixing RTA CDs with green-emissive silica nanoparticles (GCDs@SiO2) as energy donors and FRET-matched orange-emissive CDs (OCDs) as energy acceptors in aqueous solution, the delayed fluorescence of GCDs@SiO2-OCDs can be tuned from green to orange. The resulting water-processable RTA CDs can be used in information security and fingerprint recognition.
