The development of a simple and accurate quantitative method for the determination of 6-mercaptopurine (6-MP) is of great importance because of its serious side effects. Ratiometric fluorescence (RF) sensors are not subject to inter-ference from environmental factors, and exhibit enhanced precision and accuracy. Therefore, a novel RF sensor for the selective detection of 6-MP was developed. The present work reports a sensitive and selective RF sensor for the detection of 6-mercaptopurine, by hybridizing carbon nanodots (CDots) and gold nanoclusters (AuNCs) capped with bovine serum albumin (BSA). The CDots serve as the reference signal and the AuNCs as the reporter. On addition of the 6-MP, AuNCs formed aggregates, because the existing cross-links within the AuNCs and BSA structure were broken in favour of the Au-S bonds, which can enhance the fluorescence of AuNCs, while the fluorescence of CDots is stable against 6-MP, leading to distinct ratiometric fluorescence changes when exposed to 6-MP. 6-MP could be detected in the range of 0 - 30.22 μM with a detection limit of 54 nM. The developed sensor was applied for the determination of 6-MP in human serum samples and satisfactory results were obtained.

In this study, a simple Arduino-based experiment was designed to examine the acceleration of the object during free fall and to calculate the value of “g” (acceleration due to gravity). Experimental data on the free fall of a plastic box through the air was gathered with the help of an ultrasonic distance sensor (HC-SR04). Readings were taken at different intervals during the fall to obtain distance time curves. Acceleration during the free fall was then determined by applying the standard kinematic equations. The shape of the dis-tance-time graphs obtained from the experimental setup was in good agree-ment with the predicted graphs and the calculated values of g lie within the expected range. After repeated experiments, value of gravitational acceleration was found to be 9.805 m/s 2 . Hardware and software prepared for the experiment are sufficient to examine movement of ordinary objects during free fall, therefore the experiment can be easily settled in a laboratory for the pur-pose of learning and teaching.
在本研究中，设计了一个简单的基于arduino的实验来检查物体在自由落体过程中的加速度，并计算“g”的值(重力加速度)。在超声波距离传感器(HC-SR04)的帮助下，收集了塑料盒在空气中自由落体的实验数据。在下降过程中以不同的间隔进行读数，以获得距离时间曲线。然后通过应用标准运动学方程确定自由落体时的加速度。实验装置得到的距离-时间图的形状与预测图吻合较好，g的计算值在预期范围内。经过反复实验，得出重力加速度值为9.805 m/s 2。为实验准备的硬件和软件足以检测普通物体在自由落体过程中的运动，因此实验可以很容易地在实验室中进行学习和教学。
