Scientific Fields

In recent years, biosensing has played an irreplaceable position in scientific fields as well as our daily lives. A biosensor is an instrument that is sensitive to biological substances and converts its concentration into electrical signals for detection. It is an analysis tool or system composed of immobilized biologically sensitive materials as identification elements, appropriate physical and chemical transducers and signal amplification devices, and it has the functions of both a receiver and a converter. Pregnancy test sticks, blood glucose testing, etc. in life are all potential biosensors. The main point of this paper is to introduce several main techniques of biosensing for better understanding, like ELISA, fusion proteins, fluorescent probe and others. In the future, the bright future for them is also worth looking forward to if more researches and experiments can be processed in this area, for example, in the detection and treatment of cancer, medical technology can be further improved.

Absorption Characteristics

ABSTRACTOpto-chemical transducers, which exhibit changes in luminescence and/or absorption characteristics as a function of local conditions, are currently of great interest for use in performing quantitative chemical analyses. Present research is focused on the preparation and characterization of novel optrode materials which may be remotely interrogated via optical fiber carriers. The approach under investigation involves preparation of sol-gel derived films which are sensitized by the entrapment of analyte-complexing organic probe molecules. Zn(II)aq induced perturbations to the luminescence behavior of a porphyrin derivative entrapped within a porous sol-gel derived host matrix are detailed.
