Targeted drug delivery, also known as smart drug delivery or active drug delivery, is a subcategory of nanomedicine. Using this strategy, the medication is delivered into the infected organs in the patient's body or to the targeted sites inside the cells. In order to improve therapeutic efficiency and pharmacokinetic characteristics of the active pharmaceutical agents, conjugation of biomacromolecules such as proteins, nucleic acids, monoclonal antibodies, aptamers, and nanoparticulate drug carriers, has been mostly recommended by scientists in the last decades. Several covalent conjugation pathways are used for biomacromolecules coupling with nanomaterials in nanomedicine including carbodiimides and "click" mediated reactions, thiol-mediated conjugation, and biotin-avidin interactions. However, choosing one or a combination of these methods with suitable coupling for application to advanced drug delivery is essential. This review focuses on new and high impacted published articles in the field of nanoparticles and biomacromolecules coupling studies, as well as their advantages and applications.

Pain management in pregnant and postpartum people with an opioid use disorder requires a balance among the risks associated with opioid tolerance, including withdrawal or return to opioid use, considerations around the social needs of the maternal-infant dyad, and the provision of adequate pain relief for the birth episode that is often characterized as the worst pain a person will experience in their lifetime. This multidisciplinary consensus statement from the Society for Obstetric Anesthesia and Perinatology, the Society for Maternal-Fetal Medicine, and the American Society of Regional Anesthesia and Pain Medicine provides a framework for pain management in obstetrical patients with opioid use disorder. The purpose of this consensus statement is to provide practical and evidence-based recommendations and is targeted to healthcare providers in obstetrics and anesthesiology.

Exosomes are nanoscale extracellular vesicles widely present in various body fluids. They carry a variety of substances, including proteins, lipids, and nucleic acids, and play significant roles in the body by participating in immune regulation, intercellular signal transduction, and the transport of proteins and nucleic acids. Exosomes can regulate tumor development and drug resistance by modulating ferroptosis.

Objectives: Small interfering RNA (siRNA) can silence disease-related genes through sequence-specific RNA interference (RNAi). Cationic lipid-based liposomes effectively deliver nucleic acids into the cytoplasm but often exhibit significant toxicity. This study aims to synthesize a novel ionizable lipid, Nε-laruoyl-lysine amide (LKA), from natural amino acids, constructed LKA-based liposomes, and perform physicochemical characterization and cell-based experiments to systematically evaluate the potential of these ionizable lipid-based liposomes for nucleic acid delivery.

Mechanisms for absorption improvement of drugs with low water-solubility by self-microemulsifying drug delivery system (SMEDDS) are still controversial except for solubility improvement. We attempted to clarify the mechanisms by utilizing model drugs classified as biopharmaceutics classification system class II. In the in-vitro transport study for microemulsions (MEs) formed from SMEDDS, the permeation clearance (CL) calculated based on free drug concentrations in MEs, was significantly larger than the CL for aqueous solution.

Traditional mRNA vaccine formulation loaded by lipid nanoparticle (mRNA-LNP) has several shortcomings in clinical application, including the need for cryopreservation, discomfort associated with intramuscular injections, and the risk of liver aggregation. Dissolvable microneedles (DMNs), as a novel transdermal drug delivery platform, can overcome the skin barrier to deliver drugs directly into the skin in a minimally invasive manner. However, mRNA-LNP is unstable and easily degraded during the solidification of DMN.
