Biosensor technology has developed extremely rapidly in recent years. This technology brings along precise measurements as well as specific measurements. Thanks to its ability to be miniaturized and be easily accessible to the end user, it is one-step ahead of other similar methods. The selectivity of biological molecules and the sensitivity of electrochemical methods enable the continuous evolvement of these new technologies. In this chapter, the use of nucleic acids as both recognition agents and target molecules, the way they are used in biosensor technology and their electrical properties are explained in detail with examples. Aptamers, which are synthetic nucleic acids, and their use in electrochemical biosensor systems with different electrochemical and immobilization methods have been compared extensively.

Clinical Determination

Nowadays, rapid determination of several viruses which caused pathogen diseases is really important. Most of rapid detection of human pathogen viruses was developed by using biosensor technology. Biosensor technology offers several advantages, such as simple, efficient, low cost, fast response, easy to operate, and reliable. Viral detection by using biosensor can also avoid the delay of diagnosis, so the doctor can determine the type of drugs quickly and also can decide the type of patient care, properly. Most of biosensor for virus detection was exploited by using electrochemical principle, with amperometric and volumetric transducer. Almost of virus biosensor used immobilized antibody onto electrode surface as a biorecognition element. Some of viruses that could be detected by using electrochemical biosensor are HCV, HBV, HIV and influenza virus. However, quality control of the biosensor result is important, so the biosensor could be selected as an alternative method for on-site determination, especially in clinical determination.

Au Thin Films

In a study of the properties of a Ta-Au metallization system for thin film technology application, the interdiffusion between Ta(bcc)-Au, βTa-Au and Ta2M-Au films was studied. Considered here is a discussion of the use of the transmission electron microscope(TEM) in the identification of phases formed and characterization of the film microstructures before and after annealing.The films were deposited by sputtering onto silicon wafers with 5000 Å of thermally grown oxide. The film thicknesses were 2000 Å of Ta and 2000 Å of Au. Samples for TEM observation were prepared by ultrasonically cutting 3mm disks from the wafers. The disks were first chemically etched from the silicon side using a HNO3 :HF(19:5) solution followed by ion milling to perforation of the Au side.

Teachers Perceptions

The integration of Information and Communications Technology (ICT) in classrooms has been a challenge for the educational systems that aim to cope with the needs and the demands of the 21st century. The TPACK framework represents the knowledge needed by teachers bringing together content knowledge, technological knowledge and pedagogical knowledge with the aim of integrating ICTs into teaching-learning processes. The aim of this study is to determine the primary science teachers’ perceptions of technological pedagogical content knowledge (TPACK) addressing teachers’ perceptions of the affordances of technology application in instruction. A total of 133 prımary science teachers in Malaysia were surveyed (Female= 67, Male= 66). Data were collected through “Technological Pedagogical and Content Knowledge” (TPACK) scale. The questionnaire consisted of 47 questions about TPACK and is based on the survey instrument developed by Schmidt et al. (2009). TPACK involving the seven factors of technological knowledge (TK), pedagogical knowledge (PK), content knowledge (CK), technological content knowledge (TCK), technological pedagogical knowledge (TPK), pedagogical content knowledge (PCK), as well as synthesized knowledge of technology, pedagogy, and content (TPC). The findings indicate that primary science teachers perceive higher self-confidence in pedagogical knowledge in general. Further, no differences between science teachers’ perceptions according to thier gender, while there are diferences between the teachers perceptions of PK, CK, and PCK accordıng to their age
