[ 1 ] - Design and Fabrication of Biosensor Based on Immobilized AchE on Modified Electrode by Graphene-multiwall Carbon Nanotubs/Beta Cyclodexterin-chitosan
Organophosphorus (OP) forms an important class of toxic compounds. They inhibit acetyl cholinesterase (AChE, EC 3.1.1.7) that results in respiratory and myocardial malfunctions. Pesticides could be accumulated in vegetables and fruits, so detection of them is very important. The goals of this study are decreasing detection time and detection limit of methyl parathion bioprobe. In this research ...
[ 2 ] - Design and Fabrication of Glucose/O2 Enzymatic Biofuel Cell
Enzyme-based biofuel cells (EBFCs) are systems that use a variety of organic compounds to produce electricity through oxido-reductase enzymes, such as oxidase or dehydrogenase as biocatalysts immobilized on electrodes. In this study, a single-chamber EBFC consisting of carbon electrodes that operating at ambient temperature in phosphate buffer, pH 7 is reported. The EBFC anode was based on gluc...
[ 3 ] - Isolation and Study of S-layer Nanostructure of Deinococcus Radiodurans R1
Crystalline surface layer proteins (S-layer proteins) have considerable potential for the crystalline arrays in biotechnology, biomimetics and nonlife applications, including areas such as microelectronics and molecular nanotechnology. The extensive application potential of surface layers in nanobiotechnology is according to the particular inherent attributes of the single molecular arrays cons...
[ 4 ] - Designing a Label Free Aptasensor for Detection of Methamphetamine
A label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (MA) by the immobilization of thiolated self-assembled DNA sequences on a gold nanoparticles-chitosan modified electrode is constructed. When MA was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...
[ 5 ] - Immobilization of Subtilisin Carlsberg on Modified Silica Gel by Cross-linking and Covalent Binding Methods
Proteases are important enzymes that their role in various industries is undeniable. However, keeping enzymes stable during its activity in harsh conditions is so important. In this study, protease enzyme was immobilized on the porous silica particles and its stability in different temperatures and pHs was evaluated. First silica particles were aminated by 3-aminopropyltriethoxysilane then the ...
[ 6 ] - Evaluation of Immobilized Bacteriorhodopsin’s Function by Laser Irridiation
Bacteriorhodopsin (BR) is a retinal protein that is a light-driven proton pump and has an important role in photosynthesis in archaebacterium Halobacterium salinarum. The BR molecule absorbs light and photochemical changes occur in it, and different intermediates will be produced in its photochemical cycle that some of them like P and Q intermediates have a long half-life. There have been many ...
[ 7 ] - ارزیابی مقاومت کارباپنمازی در سودوموناس آئروژینوزا و باکتری های خانواده انتروباکتریاسه جدا شده از نمونه های بالینی با استفاده از روش های فنوتیپی در سال 93-94
مقدمه: کارباپنم ها داروهایی با طیف اثر گسترده هستند اما مقاومت روزافزون نسبت به کارباپنم ها مشکلاتی را به وجود آورده است. سودوموناس آئروژینوزا یک پاتوژن بیمارستانی مهم تلقی می شود ، اما مقاومت به ایمی پنم که در خط دوم درمان عفونت های چند مقاومتی سودوموناس آئروژینوزا قرار گرفته، در حال افزایش است. اهمیت خانواده انتروباکتریاسه در کثرت مبتلایان می باشد و به طوریکه 30% تا 40% سپتسمی ها و7...
[ 8 ] - بررسی فاکتورهای مؤثر در بهینه‌سازی تولید پروتئین لایه سطحی HPI در سویه دینوکوکوس رادیودورانس R1، با روش سطح پاسخ (RSM)
زمینه و اهداف: پروتئین لایه سطحی جداشده از سطح باکتری‌ها، به دلیل خاصیت خودآرایی بر روی انواع سطوح و ایجاد گروه‌های عاملی منظم کاربردهای قابل‌توجهی درزمینه‌های نانو بیوتکنولوژی، مانند ساخت حسگرهای زیستی، سیستم‌های دارو رسان هوشمند و مهندسی بافت‌دارند. در این تحقیق، بهینه‌سازی ترکیبات محیط کشت ناپیوسته برای تولید پروتئین لایه سطحی HPI از سویه دینوکوکوس رادیودورانس R1 با استفاده از روش سطح پاسخ (...
