| چکیده | ||
| هدف از این مطالعه، مروری بر فناوری نانو و کاربرد آن در علوم دامی است. نانو یک واحد اندازه‌گیری است برابر با 9-10 متر و تمام اشیاء و موجوداتی که اندازۀ آن‌ها در حد 1 تا 100 نانومتر است، اشیاء و موجودات نانو مقیاس نامیده می‌شوند. خواص مواد در مقیاس نانو بسیار متفاوت از مقیاس ماکرو است. با کاهش اندازۀ ذرات، نسبت سطح به حجم افزایش یافته و خواص و عملکرد آن‌ها تغییر می‌کند. به عبارت دیگر اگر ذراتِ یک ماده خاص در حد چند نانومتر (1 تا 100 نانومتر) کوچک شود، این ذرات ویژگی‌های متفاوتی با ذرات بزرگ اولیه خواهند داشت. رنگ، شفافیت، واکنش‌پذیری، خواص الکتریکی، خواص مغناطیسی، سختی، حلّالیّت و نقطه ذوب از جمله ویژگی‌هایی هستند که با کاهش اندازۀ ذرات در اندازۀ نانومتر تغییر پیدا می‌کنند. این امر سبب شده است تا مقیاس نانو بیش از سایر مقیاس‌های مختلف در صنعت دامپروری مورد توجه قرار گیرد. در حوزۀ علوم دامی استفاده از فناوری نانو سبب بهبود در حوزه‌های مختلف از جمله تحقیقات تولید مثل، ساخت واکسن‌های دامی، حسگرها و افزایش کیفیت خوراک و بسته‌بندی مواد غذایی شده است. بنابراین، به نظر می‌رسد با توجه به تغییر خواص مواد در اندازۀ نانو و دستاوردهای حاصل شده در این زمینه، می‌توان در تحقیقات علوم دامی و در حوزه‌های مختلف، از این فناوری بهره برد. | ||

| چکیده [English] | ||
| The purpose of this study is to review nanotechnology and its application in animal sciences a Nano is a unit of measurement equal to 10-9 meters, and all objects and organisms ranging in size from 1 to 100 nanometers are called Nano scale objects and organisms. The properties of materials at the Nano scale are very different from those at the macro scale. As the particle size decreases, the surface-to-volume ratio increased and their properties and performance change. In other words, if we reduce the particles of a particular substance to a few nanometers (1 to 100 nanometers), these particles will have different properties from the original large particles. Color, transparency, reactivity, electrical properties, magnetic properties, hardness, solubility, and melting point are some of the properties that change with decreasing particle size to Nano scale. This has led to the Nano scale being considered more than any other scale, including the livestock industry. In the field of animal science, the use of nanotechnology has led to improvements in various fields, including reproductive researches, the development of livestock vaccines, sensors, and increased feed quality and food packaging. Therefore, it seems that due to the change in the properties of materials at the Nano scale and achievements in this field, this technology can be used in animal science industry in various fields. | ||
