Microbial Biosensors

Microbial Biosensors

Microbial biosensors are analytical devices that utilize living microbes to detect specific substances through measurable signals. These devices consist of two main components: biosensing organisms and signal-transducing elements. Biosensing organisms, such as Escherichia coli or Saccharomyces cerevisiae, are typically housed in multiwell plates connected to transducers, enabling rapid, real-time detection of target analytes.Signal Generation MechanismWhen a target analyte—such as...

Bacterial Signaling

Bacterial Signaling

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Background:

Microscopy and spectroscopy are crucial for scientific research and medical diagnostics.
Existing commercial platforms are often expensive and not easily portable.
Integration of advanced optical capabilities into ubiquitous mobile devices remains a significant challenge.

Purpose of the Study:

To develop low-cost, portable attachments for commercial cell phones to function as a microscope and spectrometer.
To evaluate the performance and applicability of these cell phone-based optical instruments for medical and educational purposes.

Main Methods:

Designed and fabricated two distinct attachments for a commercial cell phone, utilizing its integrated lens and image sensor.
The microscope attachment was configured for transmission and polarized light microscopy.
The spectrometer attachment was designed for visible-light spectral analysis.

Main Results:

The cell phone microscope achieved 1.5-micron resolution and a field-of-view up to 350x350 pixels with post-processing.
The spectrometer demonstrated a 300 nm bandwidth and a spectral resolution of approximately 5 nm.
Successful imaging of blood smears for potential clinical pathology diagnosis and acquisition of tissue transmission and fluorescence spectra were achieved.

Conclusions:

Cell phone attachments can effectively transform mobile devices into capable microscopy and spectroscopy tools.
These devices offer a viable, cost-effective solution for medical diagnostics and hold significant potential for scientific education.
The developed technology expands the accessibility of advanced optical analysis in resource-limited settings.
