Summary
This study introduces an ingestible biosensor system using a radio-frequency identification (RFID)-tagged capsule for direct medication adherence monitoring. This technology offers real-time tracking to improve patient compliance and enable timely interventions.
Area of Science:
- Biomedical Engineering
- Pharmaceutical Sciences
- Digital Health
Background:
- Current medication adherence monitoring relies on indirect methods like self-reports and pill counts.
- These indirect methods often lack accuracy and real-time feedback capabilities.
- There is a need for direct, objective measures of medication ingestion.
Purpose of the Study:
- To describe an innovative ingestible biosensor system for direct medication adherence monitoring.
- To present a system utilizing a radio-frequency identification (RFID)-tagged capsule for real-time ingestion detection.
- To explore the potential of this technology in improving medication compliance.
Main Methods:
- Development of an ingestible biosensor system featuring an RFID-tagged gelatin capsule.
- The RFID tag activates upon capsule dissolution in the stomach, transmitting a signal.
- A relay device captures the signal, sending time-stamped data to a cloud server for direct adherence measurement.
Main Results:
- The system provides a direct, real-time measure of medication ingestion.
- Successful transmission of unique signals from the ingestible RFID tag to a cloud-based server was demonstrated.
- The technology integrates with mobile systems for comprehensive adherence tracking.
Conclusions:
- Ingestible biosensors offer a direct and accurate method for monitoring medication adherence.
- This technology has the potential to significantly improve patient compliance through real-time monitoring and intervention.
- Further research into device design and adherence interventions is crucial for widespread adoption.

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...

01:26Oral Drug Delivery Systems: Continuous-Release Systems
222
Continuous-release drug delivery systems offer a strategic approach to maintaining therapeutic drug levels over extended periods following oral administration. By modulating the release rate of active pharmaceutical ingredients, these systems minimize fluctuations in plasma concentrations, which enhances clinical efficacy and reduces the need for frequent dosing. Such characteristics make them particularly advantageous in managing chronic diseases where patient adherence and stable drug...

01:30Modified-Release Drug Delivery Systems: Bioavailability
113
Modified-release (MR) dosage forms are designed to extend drug release over time, thereby maintaining stable plasma concentrations and reducing dosing frequency. However, their bioavailability is typically below 100% due to incomplete drug release and presystemic metabolism, and limitations in drug permeability across the gastrointestinal epithelium, all of which can restrict the fraction of the drug reaching systemic circulation. Consequently, studying the in vivo bioavailability of MR...

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...

123
Stimuli-activated drug delivery systems are designed to release drugs in response to specific physical, chemical, or biological stimuli. These systems often utilize hydrogels—three-dimensional, hydrophilic polymer networks capable of swelling in aqueous environments and retaining significant fluid volumes. Upon exposure to particular stimuli, these hydrogels undergo structural transitions that allow the embedded drug to be released. Due to this adaptive behavior, such systems are also...

Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...
