چکیده مقاله :
بخش مهم فرآیندها در شناسایی علائم مولکولی با روش های آزمایشگاهی پیچیده انجام می شود. آنچه امروزه قابل مشاهده است، مربوط به بهره برداری از دستاوردها و ترکیب آن ها به عنوان، فناوری های جدید قابل دسترس می باشند. انجام این هدف نیازمند پیشرفت فناوری های 100-1 نانومتر می باشد تا بتوانند در تجسم و حس برهمکنش های بین گیرنده ها و اجزای خاص کمک کند. نقاط کوانتومی گرافن با سهولت تولید و زیست سازگاری و سمیت کم قابل استفاده این در همه زمینه ها شده است. این نوع نقاط کوانتومی، حاوی گروه های عاملی کربوکسیلیک اسید در سطح خود هستند که قابلیت تعویض با گروه های عاملی دیگر را داشته و موجب حلالیت بسیار بالا آن ها در آب شده است. همچنین آن-ها را برای عامل دار کردن با مواد آلی مختلف مثل پلیمرها، مناسب کرده است. قالبگیــری مولکولــی روشی ســریع و دقیــق بــرای تشــخیص مولكولها و یکــی از مهمتریــن روشهــای تشــخیص و تعییــن کمــی آنها می باشد. استفاده از حسگر پلیمرهای قالب مولکولی بر پایه نقاط کوانتومی گرافن به جهت گزینش پذیری و حساسیت بالا و همچنین قابلیت انحلال در محیط های آبی، موجب عملکرد بالای آن ها استفاده در اکثر زمینه های تشخیص و اندازه گیری شده است.
An important part of molecular markers identification has been performed by sophisticated laboratory methods. What is visible today is referred to exploit the achievements and combine them as new available technologies. To accomplish this gold, we need to develop technologies of 1 to 100 nm to help imagine and sense the interactions between the receptors and specific components. Graphene quantum dots have been developed with easy production methods, biocompatibility, and low toxicity and have been applicable in all fields. This type of quantum dots contains carboxylic acid functional groups on their surfaces, which are interchangeable with other functional groups and have a high solubility in water. It also makes them appropriate for functionalizing with various organic materials such as polymers. Molecular imaging is a fast and accurate method for molecule detection and it is one of the most important methods for molecule detection and quantification. Molecularly imprinted polymer based on graphene quantum dots have being had high-performance applications in most fields of detection and measurement, due to their high selectivity and sensitivity as well as solubility in aqueous media.
