With the latest technologies enabling smartphones to work like mini computers, there are now numerous opportunities to use smartphones for the development of mobile apps. Given the multiple Operating Systems (OS) available, there is a significant demand for apps for the various platforms. To meet this demand, some apps exist to impart the necessary knowledge to make apps, while others make the programming of apps possible on these devices. Surveying both the Google Play and Apple App stores, there are a plethora of such programming apps, classified based on the various languages.
Quantification of samples is an integral step in numerous biological and chemical experiments. Spectrophotometers are often used together with colorimetric assays that react with the compound of interest in the samples. However, spectrophotometers are often costly, bulky and immobile. To increase the convenience and ease the process of spectrophotometry, the APD SpectBT was developed using the Arduino-based platform to create a smartphone dependent mobile spectrophotometer.
The counting of colonies to quantitate bacteria is an important process in labs for research, clinical diagnosis, and environmental monitoring e.g. in water. Generally counted manually, progress in technology has automated the process through colony counters that can be purchased but can be costly. While efficient, there remains also a challenge correctly detecting clustered colonies compromising inaccurate counts. Leveraging on the smartphone camera, we developed an app that processes images of colony plates and automatically counts them.
StanXY is a free standalone native Android application. It is developed to provide convenience and efficiency to graph plotting. By simply downloading the application, StanXY provides the portability to easily plot graphs on the go as compared to manual plotting and desktop graphing software. The StanXY generates a best fit line based on a set of coordinates entered by the user. The equation of the line (y = mx + c) and its coefficient of determination (R2) are calculated and displayed.
