Cambridge Researchers Develop LEDs from Electrically Insulating Nanoparticles

Scientists at the University of Cambridge have developed a new type of LED using materials previously thought impossible to power electrically. The breakthrough centers on lanthanide-doped nanoparticles, which are excellent at emitting highly pure near-infrared light but are electrical insulators, making them unsuitable for traditional LED technology. By attaching specially designed organic molecules called 'molecular antennas' to these nanoparticles, the team created a hybrid system that efficiently transfers electrical energy into the insulating material. These molecules absorb electrical charges, enter an excited triplet state, and then transfer energy to the lanthanide ions with over 98% efficiency, causing the nanoparticles to emit bright, highly pure light. The resulting LEDs, called 'LnLEDs,' operate at low voltage and produce a very narrow spectral output, making them ideal for medical imaging, optical communication, and highly sensitive detection applications. Early devices already show a peak external quantum efficiency above 0.6%, with potential for further optimization. This approach opens the door to a new class of optoelectronic devices with tailored properties for applications not previously possible, such as deep tissue imaging, precision medical sensors, and interference-resistant optical communication systems.

Nanoparticles of Different Nature in Plant Biotechnology: Effectiveness, Safety, and Prospects of Application - Cytology and Genetics

Abstract Data on the biological activity of nanoparticles of various natures—metallic (Ag, Cu, Zn, Ti), silicon (Si), and carbon nanomaterials—on plants are summarized. Their influence on the growth, development, and resistance of plants to biotic and abiotic stresses at the molecular, cellular, and organismal levels is considered. Special attention is paid to nanoparticles obtained by “green” synthesis, which are characterized by high bioactivity, biocompatibility, stability, and environmental safety. The physiological and biochemical effects of the action of nanoparticles are analyzed, in particular their influence on seed germination, photosynthetic activity, antioxidant system, expression of stress-induced genes, etc. It has been demonstrated that biosynthesized nanoparticles cause a positive effect without toxicity in most cases, while chemically synthesized analogues can cause significant negative changes in plants. The advantages of biosynthesized nanoparticles are emphasized: their high level of environmental safety, fungicidal, antibacterial, and antiviral activity. The need for further research to optimize dosage, methods of application, and assessment of long-term effects of nanomaterials, taking into account the balance between efficiency and environmental safety, is emphasized. The obtained results demonstrate the prospects for the use of nanomaterials in cell biology, physiology, and biotechnology of plants.
