Important working characteristics of the biosensors for analysis of substances in real samples are their sensitivity and linear range of determination.
First, they have rather a narrow linear range of determination and it is a characteristic trait of urease-based biosensors, which are used in urea assays.
The excellent electrocatalytic activity of the biocomposite film resulted in the detection of glucose under reduced over potential with a wider range of determination from 1.5 × 10−8 M to 1.8 × 10−3 M and with a detection limit of 3 × 10−9 M.
Moreover, a wide range of qualitative determinations, e.g. for authenticity control, sample discrimination, the assessment of sensory, rheological or technological properties, and physical attributes have been reported.
This technique has allowed us the processing of a large number of tissue specimens for a wide range of protein determinations.
The objectives of the present work were to evaluate the morphological expression and clinical relevance of several MMPs and TIMPs of biological importance in invasive ductal carcinomas of the breast, by using the tissue microarray (TMA) technique, which has allowed us to process a large number of tissue specimens for a wide range of protein determinations (Kononen et al, 1998; Camp et al, 2000).
Differential pulse voltammetry (DPV) was used as a sensitive analytical method for the determination of BPA, and a much wider linear dynamic range of BPA determination was found between 0.1 nM and 50 μM.
"We are very excited to bring her range of interests, determination to get to the bottom of the story, and her capacity to surprise, to a television audience".
A significant extension of the linear range of urea determination was demonstrated.
As the Si/Al ratio increases, hydrophobicity increases too, and the dynamic range of the determination becomes wider.
