fluorodensitometry 是由“fluoro-”（荧光）和“densitometry”（光密度测定法）组合而成的专业术语，指通过荧光技术测量物质光密度的分析方法。以下是详细解释：

1. 定义与构成

   • 词根解析：
     • Fluoro-：源自“fluorescence”（荧光），指物质吸收特定波长光后发射更长波长光的现象。
     • Densitometry：光密度测定法，用于量化物质对光的吸收或反射程度。
   • 综合含义：结合荧光特性与光密度测量，常用于检测物质浓度或分布，例如在薄层色谱（TLC）分析中通过荧光标记物定量目标成分。

2. 应用场景
   该方法在化学、生物医学领域应用广泛，如：

   • 药物分析中检测微量化合物；
   • 生物样本（如蛋白质、核酸）的定量分析；
   • 环境监测中的污染物检测。

3. 相关术语区分

   • Fluorometry：广义的荧光测定技术，不特指光密度测量。
   • Fluorodensitometric determination：专指基于荧光光密度测定的定量分析方法。

fluorodensitometry 是一种结合荧光标记与光密度测量的精密分析技术，适用于需要高灵敏度和定量的科学场景。

网络扩展资料二

Fluorodensitometry（荧光密度计）is a noun that refers to a scientific technique that involves measuring the intensity of fluorescent light to analyze the composition and quantity of substances, such as proteins or nucleic acids.

The word can be broken down into two parts: "fluoro" (meaning fluorescent) and "densitometry" (meaning the measurement of density).

Example sentence:

• The researcher used fluorodensitometry to determine the concentration of the protein in the sample. (研究人员使用荧光密度计来测定样品中蛋白质的浓度。)

Part of speech: noun

Definition: a scientific technique that measures the intensity of fluorescent light to analyze the composition and quantity of substances

Pronunciation: /flʊərəʊˌdɛnsɪˈtɒmɪtri/

Usage: Fluorodensitometry is commonly used in molecular biology and biochemistry to quantify and analyze biological molecules.

Explanation: Fluorodensitometry works by labeling a substance with a fluorescent dye and then measuring the intensity of the fluorescent light emitted by the substance. The more fluorescent light emitted, the more of the substance is present. This technique is useful for analyzing and quantifying substances in complex mixtures.

Synonyms:

• Fluorescence spectroscopy (荧光光谱法)
• Fluorescence microscopy (荧光显微镜)
• Fluorescence assay (荧光分析法)

Antonyms:

• None.
