Chlorophyll fluorescence emission spectrum inside a leaf.
Chlorophyll a fluorescence can be used as an early stress indicator. Fluorescence is also connected to photosynthesis so it can be proposed for global monitoring of vegetation status from a satellite platform. Nevertheless, the correct interpretation of fluorescence requires accurate physical models. The spectral shape of the leaf fluorescence free of any re-absorption effect plays a key role i...
متن کاملPolymeric assemblies and nanoparticles with stimuli-responsive fluorescence emission characteristics.
Fluorescent polymeric assemblies and nanoparticles (NPs) of nanoscale dimensions have become a focus of intensive investigations during the past few decades due to combined advantages such as improved biocompatibility, water dispersibility, stimuli-responsiveness, facile integration into optical detection devices, and the ability of further functionalization. In addition, the chemical compositi...
متن کاملUltrastructural alterations and HSP 70 induction in Elodea ca- nadensis Michx. exposed to heavy metals
The effects of the heavy metals lead (Pb) and cadmium (Cd) on the ultrastructure and the induction of Heat Shock Protein 70 (HSP 70) have been studied in Elodea canadensis Michx. As for the ultrastructural effects, sublethal concentrations of the metals caused alterations of the cell fine ultrastructure. Lead and cadmium induced alterations: chloroplast were swollen with altered thylakoid organ...
متن کاملQuantitative study of fluorescence excitation and emission spectra of bean leaves.
A quantitative and comprehensive knowledge of leaf fluorescence is required for the interpretation of fluorescence signals at the canopy level and also for the modelling of leaf and canopy fluorescence. In this work we present full range fluorescence excitation and emission spectra of intact leaves, expressed in units of apparent spectral fluorescence yield, from both the adaxial and the abaxia...
متن کاملExtraction of Fig Leaves to Synthesize of Ag Nanoparticles for Determination of Atorvastatin by Spectrophotometery
In this method, firstly, extracts of Fig tree leaves are taken with a simple laboratory method, and then the research begins on a very important drug in medical science. The effects of different variables such as pH, volume and type of buffer, volume of nanoparticles and time of stay were investigated. The results showed that optimal amounts of pH = 6, 1.5 mL citrate buffer, 0.15 mL optimum vol...
