The developed approach allows making a step toward stable, low-cost, and highly efficient bioimaging platforms that are spectrally tunable and have narrow emission.īiological fluids in vitro and in vivo stability lead halide perovskites microchambers microsized carriers water-resistant perovskites. Thats when his mother began a journey that would shake her beliefs to the core. ![]() Further in vitro and in vivo experiments revealed enhanced stability of PNCs even after their introduction directly into the biological microenvironment (CT26 cells and DBA mice). The obtained encapsulated PNCs demonstrate bright green emission at 510 nm (CsPbBr 3) and red emission at 688 nm (CsPbI 3) under one- and two-photon excitation, and they possess an enhanced stability in water and biological fluids (PBS, human serum) for a prolonged period of time (1 week). In this work, we have developed a universal approach for the encapsulation of lead halide perovskite nanocrystals (PNCs) (CsPbBr 3 and CsPbI 3) as water-resistant fluorescent markers, which are suitable for fluorescence bioimaging. However, their poor stability in aqueous media and biological fluids significantly limits their further use for in vitro and in vivo applications. ![]() The outstanding optical properties and multiphoton absorption of lead halide perovskites make them promising for use as fluorescence tags in bioimaging applications. ![]()
