Aspergillosis is one of the most common fungal infections that can threaten individuals with immune compromised condition. Due to the increasing resistance of pathogens to the existing antifungal drugs, it is difficult to tackle such disease conditions. Whereas, nikkomycin is an emerging safe and effective antifungal drug which causes fungal cell wall disruption by inhibiting chitin synthase. Hence, the study aims at the development of nikkomycin loaded PEG coated PLGA nanoparticles for its increased antifungal efficiency and inhibiting infections. The P-PLGA-Nik NPs were synthesized by w/o/w double emulsification method which resulted in a particle size of 208.3 ± 15 nm with a drug loading of 52.97 %. The NPs showed first order diffusion-controlled drug release which was sustained for 24 h. These nanoparticle's antifungal efficacy was tested using the CLSI - M61 guidelines and the MIC defined against and was found to be >32 μg/ml which was similar to the nikkomycin MIC. The hyphal tip bursting showed the fungal cell wall disruption. The non-cytotoxic and non-haemolytic nature highlights the drug safety profile.

Cow milk is readily adulterated due to its complex properties that can emulsify many adulterants. Among the commonly used adulterants in cow milk are hydrogen peroxide (HP) and nitrite. Commercially available HP is added to extend cow milk's shelf life, while nitrite enters through the tap or pond water added to increase cow milk's volume.

Biodegradable polymeric coatings are being explored as a preventive strategy for orthopaedic device-related infection. In this study, titanium surfaces (Ti) were coated with poly-D,L-lactide (PDLLA, (P)), polyethylene-glycol poly-D,L-lactide PEGylated-PDLLA, (PP20)), or multi-layered PEGylated-PDLLA (M), with or without 1 % silver sulfadiazine. The aim was to evaluate their cytocompatibility, resistance to biofilm formation, and their potential to enhance the susceptibility of any biofilm formed to antibiotics.

Liposomes are employed for the delivery of molecular cargo in several classes of systems. For instance, the embedding of loaded liposomes in polymeric fibrous scaffolds has enabled the creation of hybrid materials that mimic biological membranes. Liposomes with unmodified surfaces have been predominantly integrated into fibers, which leads to instabilities due to interfacial incompatibility.

The microfluidic-based point-of-care (POC) diagnostic tool has garnered significant interest in recent years, offering rapid and cost-effective disease detection. There is a growing trend toward integrating microfluidic platforms with biosensors, aligning lab-on-a-chip technologies with POC diagnostic devices. Despite numerous efforts to incorporate biosensors into microfluidic systems, researchers have performed very limited investigations on the stability of biomarker detection when biosensors operate under microfluidic shear flow conditions.

3D printing, as a layer-by-layer manufacturing technique, enables the customization of tissue engineering scaffolds. Surface modification of biomaterials is a beneficial approach to enhance the interaction with living cells and tissues. In this research, a polylactic acid/polyethylene glycol scaffold containing 30 % bredigite nanoparticles (PLA/PEG/B) was fabricated utilizing fused deposition modeling (FDM) 3D printing.
