Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

The Ideal Diode

The Ideal Diode

A diode is a semiconductor device that allows current to flow in one direction only, making it a crucial component in electronic circuits for controlling the direction of current flow. An ideal diode is a simplified version of a real diode used to understand how diodes work in circuits. It possesses two terminals: the positive anode and the cathode, which is negative. When a positive voltage is applied to the anode relative to the cathode, the diode is in a forward-biased state, allowing...
