Objectives: To use a mobile air decontamination unit (MADU) for a microbial destruction and decreased particle burden making a cleanroom controlled environment in a Centralized Chemotherapy Preparation Unit (CCPU). Good manufacturing practices (GMP) in France specify that the ambient air in the vicinity of a class III biosafety cabinet (isolator) complies with air cleanliness ISO 8 level in CCPU. This guideline has a significant impact because implementing a dedicated air handling unit (AHU) brings some engineering constraints and generates substantial additional costs.
Methods: Authors have previously studied some technical and economical aspects to evaluate the feasibility of the MADU option.
Results: Using a MADU was the chosen option. Qualification of the CCPU showed that results were in compliance with the French GMP. After one year of use, the efficiency of the MADU was confirmed. According to these results, using a MADU constitutes a beneficial option for CCPU previously equipped with an isolator when compared to renovation work involving a standard built-in AHU.

Controlled breakdown has emerged as an effective method for fabricating solid-state nanopores in thin suspended dielectric membranes for various biomolecular sensing applications. On an unpatterned membrane, the site of nanopore formation by controlled breakdown is random. Nanopore formation on a specific site on the membrane has previously been realized using local thinning of the membrane by lithographic processes or laser-assisted photothermal etching under immersion in an aqueous salt solution.

Microbubbles, acting as cavitation nuclei, undergo cycles of expansion, contraction, and collapse. This collapse generates shockwaves, alters local shear forces, and increases local temperature. Cavitation causes severe changes in pressure and temperature, resulting in surface erosion.

Compounders worldwide are responsible for ensuring that the sterile preparations they dispense are pure, potent, and safe. To achieve that result, proper cleaning and disinfection of International Organization for Standardization controlled environments must occur. Because those tasks must be performed according to established standards, the compounding pharmacist must research regulatory requirements and appropriate products for use.

Cleanrooms are controlled environments where the number of airborne particles is reduced to a level defined by an International Organization for Standardization (ISO) standard. These facilities have applications in different fields, such as the electronic, pharmaceutical, and healthcare sectors, and are also necessary for the assembly, testing and handling of space hardware. Cleanrooms are expensive to build and maintain and require the permanent designation of infrastructures and dedicated spaces within a building.

As the field of cell and gene therapy (CGT) continues to grow, so too must the infrastructure and regulatory guidance supporting the manufacture of these potentially life-saving products-especially early-phase products manufactured at an increasing number of academic or hospital-based facilities providing decentralized (or point of care) manufacturing. An important component of current good manufacturing practices, including those regulating cell and gene therapies, is the establishment of an effective environmental monitoring (EM) program. While several guidelines for establishing an EM program are available, these guidelines do not specifically address the unique aspects of manufacturing CGT products and they do not provide real-world evidence demonstrating the effectiveness of the program.
