Microhardness, Ceramic-Knoop

Sub-Second Measurements of Glutamate and Other Neurotransmitter Signaling Using Enzyme-Based Ceramic Microelectrode Arrays

We have set out to develop a novel, implantable microelectrode array that has the capabilities to detect neurotransmitters with enhanced sensitivity, selectivity, and temporal sampling capabilities compared to other current technologies

食饵实验 feeding experiment

　　 向动物的食饵中添加某种物质以研究该物质的代谢路径（添加实验），或者通过喂饲缺乏某种成分的食饵以了解该成分的作用（缺乏试验），这种试验叫食饵实验。添加实验的例子如：F.Knoop（1904）发现，添加苯乙酸喂饲给狗时，不能完全被氧化，而是以与甘氨酸结合的取代酰胺和苯乙酰氨乙酸（phe－nylaceturic acid）的形式而排出，如果给与苯甲酸，则变成马尿酸排出。利用此原理，又喂以高级脂肪酸的ω－苯环衍生物，其结果脂肪酸链的碳原子如为偶数，则排出苯乙酰胺乙酸；若为奇数碳原子

Immunostaining of Cells Adherent to Coverslips

coverslips. Those for immunostaining are placed vertically in two ceramic coverslip holders . The remainder can be stored at -70°C. 5) Coverslips in ceramic holders are washed two times in PBS. For washes and incubations, use a 250 ml beaker and a 100 ml
