Title: Innovations of Ignacy Gryczynski
Introduction
Ignacy Gryczynski is a notable inventor based in Baltimore, MD (US). He has made significant contributions to the field of fluorescence sensing and nanotechnology. With a total of 5 patents, his work has advanced the understanding and application of luminescent materials.
Latest Patents
One of his latest patents focuses on low frequency modulation sensors using nanosecond fluorophores. This innovative approach to fluorescence sensing involves a mixture of fluorophores, where one is sensitive to the desired analyte. By combining a long lifetime analyte-insensitive fluorophore with a short lifetime analyte-sensitive fluorophore, the modulation of the emission at low frequencies can be utilized to determine analyte concentration. This method can be applied to any fluorophore that changes intensity in response to an analyte, without requiring a change in lifetime. The feasibility of this modulation-based sensing was demonstrated using mixtures of 6-carboxyfluorescein and [Ru2,2′(bipyridyl)] as a pH sensor, as well as the calcium probe Fluo-3 and [Ru2,2′(bipyridyl)] as a calcium sensor.
Another significant patent describes the luminescence spectral properties of CdS nanoparticles. The study details the steady state and time-resolved luminescence of two types of novel CdS nanoparticles. These nanoparticles, formed in the presence of an amine-terminated dendrimer, exhibit blue emission that varies with the excitation wavelength. The CdS/dendrimer nanoparticles show polarized emission, with anisotropy values increasing from 340 to 420 nm excitation. Additionally, polyphosphate-stabilized CdS nanoparticles display a longer wavelength red emission maximum than bulk CdS and exhibit zero anisotropy across all excitation wavelengths. Both types of nanoparticles demonstrate strong photostability and can serve as new luminophores for various applications, including chemical sensing and DNA sequencing.
