摘要:
Provided herein is a surface acoustic wave (“SAW”) sensor device including an isolation component of a target biomolecule. A sample containing the target biomolecule is separated by its size using electrophoresis, and sequentially reacts with a SAW sensor. In other words, the device is capable of detecting the target biomolecule by separating biomolecules using electrophoresis, and applying the separated biomolecules to the SAW sensor.

A method for controlling a game character is provided. The method includes analyzing a game situation in which a character appears; and controlling a behavior of the character depending on a result of the analyzing. Accordingly, situation recognition and behavior control depending on the recognized situation are simultaneously performed using the same algorithm, so that the calculation amount can be reduced, and thus high artificial intelligence can be implemented with less computer resources. Also, a game developer does not need to implement individual behavior rules of characters depending on game situations since a situation of the game may be recognized through learning of an artificial neural network using a game database of game situations, and thus the behavior of characters can be controlled depending on the recognized situation.

Provided herein is a fluid sensor, which includes a closed reaction unit in which reaction of a fluid sample takes place. The reaction unit is tapered on a side through which the fluid is injected so as to prevent generation of air bubbles during the injection of the fluid. Thus, the sensor has improved sensitivity.

Provided is a method for amplifying a frequency variation of a detected signal in a biosensor that is used for detecting a biomolecule by measuring a change in frequency of an oscillating signal, the change being caused by pressure a biomolecule applies to a piezoelectric substance. The method for amplifying a frequency variation of a detected signal comprises the steps of: (a) applying a sample to a probe being fixed to an upper portion of a substrate of the biosensor to allow a biomolecule in the sample to be bound to the probe; (b) applying protein tagged with a metal particle to the biosensor to allow the protein and the biomolecule to be bound with each other; and (c) applying a metal enhancer to the biosensor to allow the metal enhancer to be bound to the metal particle having been bound to the protein.

A surface acoustic wave (“SAW”) device including a SAW element, a first material, a luminescence material and a light source, and a method for signal amplification of a SAW element. The first material may be positioned on the SAW element and bound to a target material in a sample. The luminescence material may be bound to the target material. The light source may apply light to the luminescence material. The SAW device and the method for signal amplification of a SAW element using the same allow amplification of a signal of the SAW element by an electromagnetic wave generated when light is applied to the luminescence material.
