ELECTROCHEMICAL MICROCELL

Domenica Tonelli, Isacco Gualandi, Stefano Gianvittorio et al. · Archivio istituzionale della ricerca (Alma Mater Studiorum Università di Bologna) · 2023

In recent years, enzymatic electrochemical biosensors have become increasingly popular in the field of rapid determination of analytes of industrial and environmental interest. The employment of such biosensors permits to avoid or limit the use of analytical methods that involve more complex and time-consuming techniques. One of the main goals in the last years is the development of reagentless electrochemical biosensors, i.e., ready-to-use devices which are directly usable by analysts regardless of their experience. In a reagentless electrochemical biosensor all the reagents which are necessary to perform the electrochemical measurement (i.e. supporting electrolytes, buffers, enzymes, co-factors) are pre-loaded onto or near the working electrode surface, thus allowing the operator to perform the electrochemical measurement by putting a small volume (i.e. 10-100 μL) of the sample onto the sensor and without the addition of reagents to the sample. In this thesis work, a reagentless amperometric biosensor has been developed by using alkaline phosphatase (ALP) enzyme as the biological recognition element and a commercial Screen-Printed Carbon Electrode (SPCE) as a transducer. This biosensor was tested toward the detection of the enzymatic substrate “sodium ascorbil-phosphate (AAP)” as an analyte. AAP is a widely used antioxidant in the cosmetic industry and can be found in several formulations such as anti age serums or hydrating creams. In the presence of alkaline phosphatase, AAP is dephosphorylated generating ascorbic acid (AA) which can be electrooxidized at the working electrode surface. To obtain a reagentless device, small electrochemical microcells were fabricated by 3D-printing and were specifically designed to host the commercial SPCE electrodes used. The possibility of pre-loading all the reagents into these 3D printed microcells and subsequently inserting SPCE electrodes inside, allowed to fabricate ready-to-use electrochemical biosensors kits for the detection of target analytes. The use of such reagentless devices allowed to perform fast electrochemical measurements by using the ALP enzyme in solution (not immobilized on the WE surface) with a minimum volume of sample required and with a higher sensitivity in respect to a traditional ALP biosensor built by immobilizing the ALP enzyme on the working electrode surface. We will demonstrate the use of these reagentless biosensors toward the determination of AAP in cosmetic samples and toward the detection of ALP enzyme in food samples.

BioSpark Microcell

Jonathan Howson · Open Science Framework · 2026

The BioSpark Microcell is an open, ethically licensed bio-electrochemical micro-power concept intended as an alternative to lithium-based micro-energy systems for low-power electronics. The architecture uses microbial or biochemical redox processes to accumulate charge within an internal storage element, enabling short bursts of power delivery suitable for LEDs, sensors, basic computational events, and STEM demonstrations. This registration serves as a formal concept disclosure, establishing open prior art and a timestamped record to enable future laboratory prototyping, educational use, and technologically curious research. It includes a patent-style technical dossier, technical whitepaper, figure plates, ethical licensing, citation metadata, and prior-art documentation. The project invites laboratories, educators, curators, and institutions to explore and extend the design space openly under a CC BY 4.0 license with a No Harmful Use addendum.

All-fiber micromachined microcell

Denis Đonlagić · Optics Letters · 2011

This Letter presents an open-path, all-fiber microcell and a micromachining method for its production. The proposed micromachining method utilizes the selective etching of a purposely designed phosphorus-doped fiber that is spliced in between two standard lead-in fibers. Microcells with various open optical-path lengths were successfully demonstrated. The proposed microcell can be used as a transmission cell or as a miniature Fabry-Perot resonator. The transmission losses and fringe contrast were experimentally investigated over a range of prototype microcells with different lengths. For example, the insertion losses below 1 dB were demonstrated for 50 μm or shorter open path prototype microcells, when immersed in dematerialized water.

microcell concentrating photovoltaics for space

Christian J. Ruud, Jeffrey M. Gordon, Noel C. Giebink · 2024

Rapid growth in the number of Earth-orbiting satellites with electric propulsion as well as plans for colonizing the Moon will dramatically increase the demand for solar photovoltaic (PV) power in space. Most of these missions will be commercially driven, heightening the need for PV systems that are more compact, lower-mass, more efficient, reliable, and affordable than ever before. In this talk, I will describe how microscale PV cells integrated with ultracompact concentrating optics offer a new opportunity to improve performance and reduce cost without sacrificing reliability. I will overview the unique constraints imposed on nonimaging concentrator design by operation in space and describe an experimental prototype <2 mm thick that achieves 26% power conversion efficiency at a geometric gain of 18x with a specific power &gap;100 W/kg and an acceptance angle of nearly &plusmn;10°.
