Therapeutic Hybrid Systems Using Hydrogels and Nanotechnology
Topical and transdermal drug delivery are advantageous administration routes, especially when treating diseases and conditions with a skin etiology. Nevertheless, conventional dosage forms often lead to low therapeutic efficacy, safety issues, and patient noncompliance. To tackle these issues, novel topical and transdermal platforms involving nanotechnology have been developed. The development of nanoemulgels for skin application is focused, encapsulating a wide variety of molecules, including already marketed drugs (miconazole, ketoconazole, fusidic acid, imiquimod, meloxicam), repurposed marketed drugs (atorvastatin, omeprazole, leflunomide), natural-derived compounds (eucalyptol, naringenin, thymoquinone, curcumin, chrysin, brucine, capsaicin), and other synthetic molecules (ebselen, tocotrienols, retinyl palmitate), for wound healing, skin and skin appendage infections, skin inflammatory diseases, skin cancer, neuropathy, or anti-aging purposes. Developed formulations revealed adequate droplet size, PDI, viscosity, spreadability, pH, stability, drug release, and drug permeation and/or retention capacity, having more advantageous characteristics than current marketed formulations.

Poly(Vinylidene Fluoride) and Copolymer-Based Piezoelectric Nanogenerators
The highest energy conversion efficiencies are typically shown by lead-containing piezoelectric materials, but the harmful environmental impacts of lead and its toxicity limit future use. At the bulk scale, lead-based piezoelectric materials have significantly higher piezoelectric properties when compared to lead-free piezoelectric materials. However, at the nanoscale, the piezoelectric properties of lead-free piezoelectric material can be significantly larger than the bulk scale.

Advantages of 2D Materials and Cellulose in Biosensors
The use of 2D materials in biosensor applications provides several advantages, including excellent mechanical, optical, and electrical properties. These properties are essential for the development of wearable biosensors that enable real-time monitoring of human health information and accurate measurement of vital signs. Integrating 2D materials into wearable biosensors has expanded opportunities for early detection of life-threatening diseases and continuous health tracking. In addition to 2D materials, cellulose-based biosensors also offer significant benefits. They are cost-effective, highly sensitive, and compatible with portable sensing devices used in biomedical applications. One major advancement in this field is the functionalization of cellulose papers with antibodies, nucleic acids, and nanomaterials in PBBs (paper-based bioassays) and μPADs (microfluidic paper-slip devices). Hence, the application of 2D materials and cellulose in medical diagnostics and biosensors has shown great potential. These materials have unique properties that make them suitable for various applications, including disease detection, real-time monitoring, and point-of-care diagnostics.

Nanotechnology Platform for Advancing Vaccine Development Against COVID-19
The COVID-19 pandemic has had a profound impact on societies, public health, healthcare systems, and the world economy. Vaccination emerged as the most effective strategy to combat this infectious disease. For vaccination strategies, any conventional vaccine approach using attenuated live or inactivated/engineered virus, as well as other approaches, typically requires years of research and assessment. However, the urgency of the situation promoted a faster and more effective approach to vaccine development against COVID-19. The role of nanotechnology in designing, manufacturing, boosting, and delivering vaccines to the host to counter this virus was unquestionably valued and assessed.

Bright and Stable Nanomaterials for Imaging and Sensing
Optical techniques for imaging and diagnosis are at the center of the wonderous developments in the biomedical field, which are paving the way to personalized medicine. Fluorescence-based techniques, in particular, have allowed dramatic progress in the analysis of biological systems and other complex processes. This is because they present better specificity, sensitivity, contrast, and versatility than techniques based on the absorption/reflection of light. Their performance is closely related to the brightness and photostability of the light-emitting materials: the amount of light emitted for a given illumination and the ability to withstand high-power illumination without degrading.

Traditional Group-IV Material Batteries through Ion Migration
Ion migration refers to the process of ions moving within a medium driven by an external electric field or a chemical gradient. The prerequisite for the implementation of ion migration technology lies in the construction of suitable electrodes, electrolytes, and media. Group-IV materials, due to their abundant raw materials, low production costs, non-toxic nature, and excellent electrochemical properties, serve as ideal anode materials for various ion migration-based batteries. Group-IV materials, as crucial components of ion migration-driven energy storage technologies, have been a focal point of research for decades. Various studies encompass the design and fabrication of rational structures, as well as selecting metal ions with different valence states (Li+, Na+, K+, Zn2+, Mg2+, Al3+, etc.) to enhance the performance of ion batteries.

Imaging Techniques for Morphological Characterization of Magnetic Films
Microscopy imaging techniques are critical for the morphological characterization of thin films because they provide nanoscale structural and compositional information that impacts properties. Techniques discussed below reveal grain size, grain boundaries, surface roughness and interfaces, and defects at high resolution. When coupled with spectroscopy, microscopy may provide compositional mapping and magnetic information. This multiscale morphological information is key to elucidating structure–property relationships in thin films.
