Special Issue Information

Dear Colleagues,

The development of new and effective drug delivery systems will depend on our ability to fully understand their behaviour once administered to patients. Depending on the route of administration, drug carriers will encounter many structures and environments that can differ widely. Although there is a broad understanding of how composition and surface properties can affect pharmacokinetics and distribution, a lot remains to be uncovered about the performance of these systems in various physiological environments, in health and disease, looking at the whole body or down to single-cell level. There is also a need to reassess how drug delivery systems are characterised in the early stages of development to ensure the conditions used reflect the physiological environment as closely as possible.

This Special Issue invites studies and reviews on all aspects related to the investigation of the behaviour of new delivery systems in physiological environments, from how disease can affect the performance of delivery systems through to interaction with cells and intracellular trafficking and suggesting new methodologies for a more thorough assessment of newly developed drug carriers.

Nanoparticles (NPs) designed for various theranostic purposes have hugely impacted scientific research in the field of biomedicine, bringing forth hopes of a future revolutionized area called nanomedicine. A budding advancement in this area is the conjugation of various cell membranes onto nanoparticles to develop biomimetic cells called ‘Nanodecoys’ (NDs), which can imitate the functioning of natural cells. This technology of coating cell membranes on NPs has enhanced the working capabilities of nano-based techniques by initiating effective navigation within the bodily system. Due to the presence of multiple functional moieties, nanoparticles coated with cell membranes hold the ability to interact with complex biological microenvironments inside the body with ease. Although developed with the initial motive to increase the time of circulation in the bloodstream and stability by coating membranes of red blood cells, it has further outstretched a wide range of cell lines, such as mesenchymal stem cells, beta cells, thrombocytes, white blood cells, and cancer cells. Thus, these cells and the versatile properties they bring along with them open up a brand-new domain in the biomedical industry where different formulations of nanoparticles can be used in appropriate dosages to treat a plethora of diseases. This review comprises recent investigations of nanodecoys in biomedical applications. Full article

Nanoparticles (NPs) are versatile candidates for nanomedical applications due to their unique physicochemical properties. However, their clinical applicability is hindered by their undesirable recognition by the immune system and the consequent immunotoxicity, as well as their rapid clearance in vivo. After injection, NPs are usually covered with layers of proteins, called protein coronas (PCs), which alter their identity, biodistribution, half-life, and efficacy. Therefore, the characterization of the PC is for in predicting the fate of NPs in vivo. The aim of this review was to summarize the state of the art regarding the intrinsic factors closely related to the NP structure, and extrinsic factors that govern PC formation in vitro. In addition, well-known opsonins, including complement, immunoglobulins, fibrinogen, and dysopsonins, such as histidine-rich glycoprotein, apolipoproteins, and albumin, are described in relation to their role in NP detection by immune cells. Particular emphasis is placed on their role in mediating the interaction of NPs with innate and adaptive immune cells. Finally, strategies to reduce PC formation are discussed in detail. Full article
