Polluted air and the presence of numerous airborne pathogens affect our daily lives. The sensitive and fast detection of pollutants and pathogens is crucial for environmental monitoring and effective medical diagnostics. Compared to conventional detection methods (PCR, ELISA, metabolic tests, etc.), biosensors bring a very attractive possibility to detect chemicals and organic particles with the mentioned reliability and sensitivity in real time. Moreover, by integrating nanomaterials into the biosensor structure, it is possible to increase the sensitivity and specificity of the device significantly. However, air quality monitoring could be more problematic even with such devices. The greatest challenge with conservative and sensing methods for detecting organic matter such as bacteria is the need to use liquid samples, which slows down the detection procedure and makes it more difficult. In this work, we present the development of a polyacrylonitrile nanofiber bioreceptor functionalized with antibodies against bacterial antigens for the specific interception of bacterial cells directly from the air. We tested the presented novel nanofiber bioreceptor using a unique air filtration system we had previously created. The prepared antibody-functionalized nanofiber membranes for air filtration and pathogen detection (with model organisms E. coli and S. aureus) show a statistically significant increase in bacterial interception compared to unmodified nanofibers. Creating such a bioreceptor could lead to the development of an inexpensive, fast, sensitive, and incredibly selective bionanosensor for detecting bacterial polluted air in commercial premises or medical facilities.

“…Electrospinning can produce fibres with diameters ranging from a few tens of nanometres (5-10 nm) to a few micrometres (5-10 µm), which is commonly used to create these mats [17]. Nanofiber mats consist of a network of interwoven fibres that form an extremely porous and lightweight structure [18]. This makes them useful for several applications in biomedical engineering [19; 20], energy [21], and environmental sciences [22].…”

“…Hence, enhancing the separator performance is a top research priority [28]. The advantage of employing the PAN nanofiber mat in the composite is that it has a higher strength compared to the PA6 nanofiber mat [18], but the disadvantage is that it has a bigger porosity than the PA6 nanofiber mat; whereas the PA6 nanofiber mat has extremely low porosity, making it a suitable separator in batteries [29]. This study focuses on the fabrication of polymeric composite mats and the mechanical characteristics of these nanofiber mats.…”

In recent years, as microelectronics technology advances, the number of miniature devices has increased as well as the demand for power supply. Polymer-based electrospun nanofiber membranes have been used as lithium-ion (LI) battery separators and filtration medium. This study investigates the mechanical properties of orientated polyamide 6 (PA6) and polyacrylonitrile (PAN) nanofiber mats prepared by electrospinning a solution containing PAN and PA6, separately. The PA6 granules and the PAN powder were dissolved in formic acid solvent and N, N-dimethylformamide solvent, respectively. To generate the composite mat, the PA6 nanofiber mat was first electrospun, followed by the PAN nanofiber mat directly electrospun on the PA6 nanofiber mat. In our experiment, we employed the following electrospinning parameters: a voltage of 25 kV, a flow rate of 0.65 ml/h, 25 cm between the tip of the syringe and the drum collector centre, and a constant rotating speed of 1800 rpm. The mechanical properties of nanofiber composite mats, such as the tensile strength and Young’s modulus, were examined. The results demonstrate a reduction in the tensile strength and an increase in the elastic modulus of the composite nanofiber mats by 12% and 126% compared to PA6 nanofiber mats, respectively. The structure of spun nanofibers enables their use as separators for lithium-ion batteries and as a filtering medium. This article suggests the improved mechanical characteristics of nanofiber membranes for use as a barrier in lithium-ion batteries and for filtration.

“…However, while the objective of rejuvenating the existing city has been high on national and international administrative agendas for some time, the techniques and means of altering the physical environment have remained more complex. Furthermore, it evaluates the economic benefits of using the existing building stock and building materials by using smart materials [5][6][7] instead of destruction and reconstruction. [8].…”

Property reuse secures the reuse of developed land as part of new projects, cleans up polluted properties, and reuses and uses the land around development or social housing. Identifying unoccupied land and determining which properties may be used for social housing are significant challenges to regenerating idle land. Most municipalities need appropriate economic incentives to assist in maintaining and restoring unoccupied land, abandoned constructions, cultural assets, and historical buildings. It is challenging to determine deserted terrain using picture classification, since the morphology of such areas can include, among other characteristics, abandoned structures and barren soil. Although it may solve significant issues, social housing offers people a secure, long-term residence. In many countries, social integration remains the main objective of the social housing sector. However, the sector has an increasing proportion of low-income and vulnerable renters and a smaller range of income levels. This may threaten the industry’s economic viability and exacerbate the geographical concentration of poverty and disadvantages. What will the total effect of the reuse of property for social housing be? is the research question. What types of properties may be used for social housing? How do you recognise them? Furthermore, what effects would the repurposing of properties for social housing have? This research uses qualitative content analysis to discuss the location of houses for reuse and conversion to social housing. Additionally, the implications of social housing were examined.
