Summary: Carbon dots (CDs) have gained attention for their biocompatibility and tunable photoluminescence, but further analysis is needed before their use in clinical trials. A new type of carbon nitride dot (CND) has been found to selectively uptake cancer cells due to structural similarities with glutamine. The study investigates the effects of surface structural differences on the cellular uptake of CNDs and finds that the uptake mechanism is linked with ASCT2 and LAT1 transporters. CNDs show promise for selective cancer cell targeting by utilizing highly expressed transporters on cancer cells.

Summary: Metal-containing nanomaterials have diverse compositions and structures, making them attractive for various applications. In this study, we modified dendritic polyethylene glycol on a folate-nickel nanotube to create a new type of metal-containing nanotube, PEG-FA-Ni NTs. These nanotubes exhibited excellent antitumor activity comparable to commonly used drugs, and may achieve optimal antitumor effects by damaging DNA, blocking cell cycle, and inducing apoptosis. The results suggest that PEG-FA-Ni NTs could be a promising nanomedicine for cancer therapy.

Summary: Researchers have explored the use of ferroelectric materials to improve the performance of two-dimensional photonic and optoelectronic devices. Ferroelectrics can adjust the carrier concentration, mobility, and bandgap of two-dimensional materials, allowing for control over their photonic and optoelectronic properties. The polarization of ferroelectrics can be modulated by incident light, and the wavelengths of light can be tuned by switching the polarization, thereby enhancing the performance of two-dimensional photonic and optoelectronic devices. Two-dimensional materials have great potential in photonics and optoelectronics due to their tunable bandgap.

Summary: Perovskites have great potential for use in photodetectors due to their exceptional electrical and optical properties. By integrating two-dimensional materials with perovskites, it is possible to achieve excellent optoelectrical properties by utilizing the high carrier mobility of the 2D materials and strong light absorption of perovskite. In this study, a photodetector based on the WTe2/CsPbI3 heterostructure is demonstrated. The WTe2/CsPbI3 heterojunction facilitates efficient charge transfer, leading to quenching and shortened lifetime of photoluminescence for CsPbI3 perovskite. Coupling with WTe2 significantly improves the photoresponsivity of the CsPbI3 photodetector due to the high-gain photogating effect. The WTe2/CsPbI3 heterojunction photodetector exhibits a large responsivity of 1157 A W-1 and a high detectivity of 2.1 x 10(13) Jones, paving the way for high-performance optoelectronic devices based on 2D materials/perovskite heterojunctions.
