Microbial Aerosols: Sources, Properties, Health Effects, Exposure Assessment—A Review Read more
Editor’s picks

Microorganisms are ubiquitous in the Earth’s biosphere. Majority of them poses a threat for humans, being either naturally occurring or artificially introduced into the air and forming bioaerosols. Bringing together the contemporary status of information in the area, this ‘eye-opening’ article characterizes in condensed form the environmental sources of microbial aerosols, their role in atmospheric processes, provides their physical and biological characteristics which result in adverse health effects, discusses analytical techniques used for their quantitative and qualitative evaluation, presents methods for establishing standards of exposure, and comments on their usefulness in the control and protection of environment and health.

Fine Particle Filtration Technology Using Fiber as Dust Collection Medium Read more
Editor’s picks

Despite the facts that the applied particle concentration and the field of usages are completely different, air filter and bag filter are regarded as similar because of at the point of using fine fibers as dust collecting body. The article reviewed the collection performance of a single fiber collection efficiency at different mechanisms and time changes of collection performance of both filters is reviewed precisely based on numerous previous studies.

Challenges Associated with the Pulmonary Delivery of Therapeutic Dry Powders for Preclinical Testing Read more
Editor’s picks

Inhaled dry powder therapeutics occupy a growing sector in the pharmaceutical market and meet demands unmet by alternative formulation counterparts. The dry powder inhaler offers the benefits of short delivery times, ease of administration, increased bioavailability, and excellent shelf-life. However, dry powder therapeutics have not transitioned to the market at the same rate as alternative pulmonary delivery platforms. This article addresses some of the barriers to the success of dry powder therapeutics from the preclinical stage to the market. The article concludes with a discussion on improvements needed to address current research model failures and identifies barriers to dry powder formulation and development.

Droplet Microfluidics as a Tool for the Generation of Granular Matters and Functional Emulsions Read more
Editor’s picks

Droplet microfluidics is a novel discipline of science dealing with generation, manipulation and creative use of emulsions - fluidic equivalent of granular matter. In this work Authors provide a comprehensive introduction to droplet microfluidics. The review covers fundamentals and presents some of the most important applications of the emulsions - representative to the broad interest in droplet microfluidics ranging from material science, through biomedical experiments and diagnostics, to applications in pharmaceutical, food, and cosmetic industries.
