The present invention provides systems and methods for determining enzymatic competency, which is important in determining whether a patient may suffer an adverse drug reaction, has a disease associated with defects in specific enzymatic function, and/or has an enzyme defect that is likely to cause pathophysiology. As contemplated herein, a parent molecular entity is administered to a patient in whom enzymatic competency is to be determined. A sample of the patient's bodily fluid is exposed to a sensor of the invention to distinguish, detect, and quantify a detectable entity in the bodily fluid. Sensor-acquired data regarding the detectable entity is used to determine enzymatic competency. Preferably, a sample of a patient's exhaled breath is collected and exposed to the sensor of the invention. Types of sensor systems of the invention include, but are not limited to, surface resonance arrays; microelectromechanical sensors (such as microcantilever-based technology); molecularly imprinted polymer sensors; amplifying fluorescent sensor technology; aptamer-based sensor technology; SAW sensors; infrared sensors; fuel cells; chemical reactors; and pH sensitive sensors.
本发明提供了确定酶的能力的系统和方法,这对于确定患者是否可能遭受不良药物反应、是否患有与特定酶功能缺陷有关的疾病以及是否存在可能导致病理生理学的酶缺陷非常重要。如本文所述,将一种母分子实体注入到需要确定酶能力的患者体内。将患者体液样品暴露于本发明的传感器上,以区分、检测和量化体液中的可检测实体。使用传感器获取的有关可检测实体的数据来确定酶的能力。最好收集患者呼出的气息样品并将其暴露于本发明的传感器上。本发明的传感器系统类型包括但不限于表面共振阵列、微电子机械传感器(如基于微悬臂臂技术)、分子印迹聚合物传感器、放大荧光传感器技术、适配体传感器技术、SAW传感器、红外传感器、燃料电池、化学反应器和pH敏感传感器。
