Source: Logan G. Kiefer, Andrew R. Falkowski, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a thin coating on an electrode. Other thin film deposition techniques include chemical vapor deposition (CVD), spin coating, dip coating, and sputter deposition among others. CVD uses a gas-phase precursor of the element to be...

Anti-retroviral therapy to treat HIV/AIDS is monitored in South Africa on a large scale. Flow cytometry is combined for haematology (CD45), immunology (CD4) and viral-load linked CD38 assay. Recorded at NHLS-SA laboratories, Johannesburg, these modern methods are cost-efficient with heightened local internal quality control, serving as role-models for resource-limited diagnostics.

We describe a method for the fabrication of large-area (up to 13 cm diameter) and ultrathin (as thin as 8 nm) polymer films. Instead of using a sacrificial interlayer to delaminate the film from its substrate, we use a self-limiting surface treatment suitable for arbitrarily large areas.

The two-thermal annealing method enables the fabrication of thin films of type II semiconductor silicon clathrate. Post-synthesis treatments, including thermal pressing and reactive ion etching, were performed to improve the material properties. This approach provides an accessible pathway for fabricating tunable clathrate films suitable for next-generation electronic and photonic devices.

Decontamination for Laboratory Biosafety

2023
Robert M. Rioux and Zhifeng Chen, Pennsylvania State University, University Park, PA Decontamination is essential for laboratory biosafety, as the accumulation of microbial contamination in the laboratory can lead to the transmission of disease. The degree of decontamination can be classified as either disinfection or sterilization. Disinfection aims to eliminate all pathogenic microorganisms, with the exception of bacterial spores on lab surfaces or equipment. Sterilization, on the other hand,...
FAQs
Stretching allows the film to conform closely to the shape of a tube, flask, plate, or vial opening. This close fit helps create a barrier without requiring the vessel to have a standard shape or size. As a result, the covered container is better protected against spills, evaporation, and exposure to airborne contaminants during biological work.
The film can help limit changes caused by evaporation and reduce unwanted exposure from the surrounding air. These effects are important when cultures or samples need more consistent conditions during handling or storage. It does not independently control every experimental variable, but it supports procedures by helping preserve the condition of the material inside the covered vessel.
Laboratory film provides a physical barrier, but the overview identifies it as a complement to sterile technique rather than a substitute. Sterile practice remains part of maintaining sample and culture integrity, while the film helps reduce exposure after a container is covered. Using both approaches supports more consistent biological procedures and reduces handling-related risks.
The film is placed over the vessel opening and stretched so it conforms to the container. Once the opening is covered, the close-fitting barrier helps limit spills, evaporation, and airborne exposure. When access is needed, the film can be removed, allowing the container to be handled without permanently altering the vessel or its contents.
Its uses extend across cell culture, microbiology, molecular biology, and sample storage. In each setting, the purpose is to protect cultures or samples while helping preserve experimental conditions during handling or temporary storage. The same adaptable sealing approach can therefore support different biological workflows involving tubes, flasks, plates, vials, or other covered containers.
By helping limit evaporation, spills, and exposure to airborne contaminants, laboratory film can reduce some sources of unwanted variation during biological work. It also helps lower handling risks when cultures or samples are covered. These protective effects support the integrity of procedures and can contribute to more stable, reproducible outcomes when combined with appropriate laboratory practices.
