Abstract: Calcium hydroxide nanoparticles (Ca(OH)2NPs) synthesized using carob pulp extract may be hexagonal nanoparticles with a diameter ranging from about 31.22 nm to about 81.22 nm. The Ca(OH)2NPs may be synthesized by heating ethylene glycol, adding calcium hydroxide to the ethylene glycol to provide a first mixture, heating the first mixture, adding a carob pulp aqueous extract to the first mixture to form a second mixture, heating the second mixture, adding sodium hydroxide (NaOH) to the second mixture to form a third mixture, heating the third mixture, resting the third mixture at room temperature after heating, centrifuging the third mixture, collecting a colloid sediment, extracting any unwanted contaminants from the colloid sediment, and drying the colloid sediment to obtain Ca(OH)2NPs.

Abstract: A method of synthesizing silver nanoparticles includes using sesame (Sesamum indicum) oil cake extract as a reducing agent. The silver nanoparticles can range in size from about 6 nm to about 15 nm. The silver nanoparticles can have an average particle size of about 10 nm.

Abstract: The synthesis of silver nanoparticles from plant extract includes providing a solution including silver nitrate; providing an aqueous extract of the Abelmoschus esculentus (Okra) plant or plant part; mixing the silver nitrate solution and the extract solution to form an aqueous mixture; and resting the aqueous mixture for a period of time to form silver nanoparticles (AgNPs). The resulting silver nanoparticles demonstrate antimicrobial activity against both gram-positive and gram-negative pathogens.

Abstract: The method of detecting bladder cancer by optical analysis of bodily fluids utilizes optical techniques to determine a concentration of porphyrin in a patient's bodily fluid sample. The patient is administered 5-aminolevulinic acid and, approximately eight hours later, a bodily fluid sample is collected from the patient, and this bodily fluid sample is optically analyzed to measure a concentration of porphyrin therein. Optical analysis is preferably performed by laser-induced fluorescence spectroscopy. If the measured concentration of porphyrin is approximately three times a pre-determined porphyrin concentration for a healthy person of the same age as the patient, then the patient is diagnosed with bladder cancer.

Abstract: The spectral method for quantifying hemoglobin fragility caused by smoking is based on decreased concentration of tryptophan and elevated concentrations of the biomolecules nicotinamide adenine dinucleotide (NADH), flavin adenine dinucleotide (FAD), and porphyrin in the presence of hemoglobin fragility. The method involves the steps of obtaining a blood sample from a patient who is a smoker; separating blood plasma from the samples; obtaining synchronous excitation spectra (SXS) of the blood plasma with a spectrofluorometer at a scan offset of 70 nm and at a scan offset of 10 nm; comparing the patient's SXS with the SXS of normal control samples; and diagnosing hemoglobin fragility when the excitation maxima of NADH, FAD, and porphyrin are between 30% and 70% higher than the maxima for these metabolites in the normal control samples, or when the excitation maximum for tryptophan is 60% of the control sample.

Abstract: The synthesis of silver nanoparticles from Pimpinella anisum L seeds includes providing a silver nitrate (AgNO3) solution, providing an extract of Pimpinella anisum L. plant seeds, and combining the silver nitrate solution with the extract of the Pimpinella anisum L. plant seeds to produce silver nanoparticles. The synthesis of silver nanoparticles from Pimpinella anisum L. seeds does not require toxic chemical solvents.
