Novel graphitic carbon nitride nanocones (g-CNNCs) were synthesized for the first time in this study. The SEM, TEM, XPS and FT-IR were used to research the structure of the g-CNNCs. We found that the g-CNNCs showed high selective and sensitive for fluorescence enhancement detection of Pb ion via covalent interaction. In addition, the g-CNNCs exhibit stable and specific concentration-dependent fluorescence intensity in the presence of Pb ion in the range of 1-200 μmol·dm, and the limit of detection was estimated to be 0.0438 μmol·dm (3S/k). More importantly, the g-CNNCs were used to detect practical samples with satisfactory results.

A new fluorescent sensor was designed and synthesized from 5-nitro-1,2-dihydroacenaphthylene, n-butyl amine and 1-(2-pyridyl)piperazine. In DMF/HO (3:1, v/v), the sensor showed excellent selectivity a...
A cerium-based metal-organic tetrahedron has been developed as a highly selective and sensitive fluorescence sensor for the recognition of 4-amino-2,6-dinitrotoluene (4-ADNT). The redox-active tetrahe...
Carbon dots (C-dots) were used to study the binding mechanisms with serum protein, bovine serum albumin (BSA) by using two notable binding systems known as non-covalent and covalent interaction. Inter...
A simple phosphoryl quinolone (L) based sensor has been synthesized for the selective recognition of Lu by spectrofluorimetric method. In methanol-water (1:1, v/v), the ligand L exhibits a weak emissi...
The interaction of fluorescent dyes with serum proteins has garnered significant interest owing to potential for non-covalent labeling and imaging applications. In this work, dimeric benzothiazole-bas...
This study is designed to evaluate background fluorescence of participants of different ages, gender, and skin color. In addition, 48-hour tolerability of the sensor and adhesive will be e...
The goal of this clinical research study is to learn about a new minimally invasive glucose monitoring device called Fluorescence Affinity Sensor (FAS). In this study, the FAS will be used...
The aim of this study was to evaluate the impact of fluorescence imaging on the location of colorectal transection lines based on evaluation of perfusion with indocyanine green, how it's g...
Cystic Fibrosis (CF) is a hereditary multi-system disease affecting approximately 30,000n children and adults in the USA. The diagnosis of CF requires biochemical confirmation (either abno...
This study aims to evaluate the feasibility of indocyanine green (ICG)-based fluorescence imaging in the detection of prostate tumors and metastatic lymph nodes. By correlating the ICG flu...
A stromal interaction molecule that functions as a highly sensitive calcium sensor in the ENDOPLAMSIC RETICULUM and CYTOSOL. It can regulate CALCIUM RELEASE ACTIVATED CALCIUM CHANNELS in response to minor variations in intracellular calcium.
Fluoroimmunoassay where detection of the hapten-antibody reaction is based on measurement of the increased polarization of fluorescence-labeled hapten when it is combined with antibody. The assay is very useful for the measurement of small haptenic antigens such as drugs at low concentrations.
A scanning microscope-based, cytofluorimetry technique for making fluorescence measurements and topographic analysis on individual cells. Lasers are used to excite fluorochromes in labeled cellular specimens. Fluorescence is detected in multiple discrete wavelengths and the locational data is processed to quantitatively assess APOPTOSIS; PLOIDIES; cell proliferation; GENE EXPRESSION; PROTEIN TRANSPORT; and other cellular processes.
A benzofuran derivative used as a protein reagent since the terminal N-NBD-protein conjugate possesses interesting fluorescence and spectral properties. It has also been used as a covalent inhibitor of both beef heart mitochondrial ATPase and bacterial ATPase.
The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.
