    Abstract Dementia impairs memory, critical thinking, and decision-making. Alzheimer's disease is caused by extracellular amyloid fibrils containing the peptide Amyloid beta (Aβ) accumulating in the brain. Alzheimer's disease is the most common form of dementia. A slew of small molecule inhibitors developed over several decades has targeted dementia and related diseases. The drugs and inhibitors cannot cross the BBB due to their insurmountable nature. Many molecular nanomedicines have been developed that can cross the BBB via adsorptive-mediated transcytosis. Drug-loaded nanosized formulations, such as polymeric nanoparticles, solid lipid nano transporters, liposomes, nanoemulsions, exosomes, gold nanoparticles, and dendrimers, have a significant impact on dementia diagnosis and treatment. This review focuses on recent developments in nanotechnology-based drug delivery systems for dementia and related disorders such as Alzheimer's disease. Recent advances in nanotechnology may help overcome drug delivery limitations for dementia therapy. Nanoparticles' size, composition, and structural variety bring up new therapeutic possibilities, including treating and diagnosing neurodegenerative diseases. It is possible to enhance therapeutic effectiveness by enhancing pharmacokinetics, bioavailability, water solubility, and stability under physiological conditions while reducing adverse effects by restricting their location in healthy tissues.

    Abstract Despite advances in cytotoxic treatments, colorectal cancer remains a leading cause of death. Metastatic colorectal cancer (mCRC) patients have a poor prognosis despite improved treatments and more prolonged median survival. Monoclonal antibodies like cetuximab and panitumumab target the epidermal growth factor receptor (EGFR). They play an essential role in the treatment of metastatic colorectal cancer (mCRC) due to their efficacy in multiple phase III clinical trials across multiple treatment lines. It was discovered that anti-EGFR moAbs were only effective for a small number of patients. Mutations in KRAS and NRAS have been identified as biomarkers of drug resistance. New molecular predictors and prognostic markers are used clinically. The K-Ras mutation is the first molecular marker of a lack of response to EGFR-targeted therapy in K-Ras-mutant patients. Validating predictive and prognostic markers will improve cancer treatments. This article examines molecular markers that can predict colorectal cancer prognosis.

    Abstract Colorectal cancer (CRC) is common cancer that is one of the leading causes of cancerrelated deaths around the world. The creation of new biomarkers for this disease is an important public health strategy for lowering the disease's mortality rate. According to new research, exosomes may be important sources of biomarkers in CRC. Exosomes are nanometer-sized membrane vesicles (30-200 nm) secreted by normal and cancer cells that transport RNA and proteins between cells and are thought to help with intercellular communication. Exosomes have been linked to CRC initiation and progression, and some differentially expressed RNAs and proteins in exosomes have been identified as potential cancer detection candidates. As a result, studying the relationship between exosomes and CRC may aid in the development of new biomarkers for the disease. This article discusses the importance of exosomes as biomarkers in the diagnosis of CRC, as well as their use in the treatment of CRC metastasis, chemoresistance, and recrudescence. The benefits and drawbacks of using exosomes as tumour markers are also discussed.

    Abstract Nanocarriers have emerged as a promising class of nanoscale materials in the fields of drug delivery and biomedical applications. Their unique properties, such as high surface area-- to-volume ratios and enhanced permeability and retention effects, enable targeted delivery of therapeutic agents to specific tissues or cells. However, the inherent instability of nanocarriers poses significant challenges to their successful application. This review highlights the importance of nanocarrier stability in biomedical applications and its impact on biocompatibility, targeted drug delivery, long shelf life, drug delivery performance, therapeutic efficacy, reduced side effects, prolonged circulation time, and targeted delivery. Enhancing nanocarrier stability requires careful design, engineering, and optimization of physical and chemical parameters. Various strategies and cutting-edge techniques employed to improve nanocarrier stability are explored, with a focus on their applications in drug delivery. By understanding the advances and challenges in nanocarrier stability, this review aims to contribute to the development and implementation of nanocarrier- based therapies in clinical settings, advancing the field of nanomedicine.

    Abstract This review investigates the revolutionary application of cell membrane-coated nanoparticles (CMNPs) as a promising avenue for cancer therapy within the embryonic landscape of nanotechnology. Nanoparticles, pivotal in cancer treatment, are systematically examined for their diverse physicochemical structures, categorized as organic (lipid-based, protein-based, and polymer-assisted) and inorganic (carbon-based and metal) varieties. A significant focus is placed on CMNPs, which serve as an innovative drug delivery vehicle, overcoming limitations associated with conventional nanoparticle therapies. This manuscript accurately explores the advantages and challenges of various cell membranes, including those derived from cancer cells, red blood cells, platelets, stem cells, and white blood cells. Importance is placed on their roles in enhancing drug delivery precision, immune system circumvention, and targeted recognition. Detailed insights into the crafting of CMNPs are provided, elucidating membrane extraction and fusion techniques, such as sonication, extrusion, co-extrusion, and microfluidic electroporation. Maintaining membrane integrity during extraction and the benefits of coating techniques in augmenting biocompatibility and targeted drug delivery are underscored. This comprehensive resource consolidates the latest advancements in targeted drug delivery, positioning itself at the forefront of nanotechnology and biomedicine research. Encapsulating various methodologies like membrane extrusion, electrospray, and chemical conjugation, this manuscript showcases the expanding toolbox available to researchers in this dynamic field. Focusing on the unique characteristics of CMNPs, this review explores their multifaceted applications in biomedical research, particularly in tumour therapy. It provides an indepth analysis of the biocompatibility of CMNPs, their stability, immune evasion capabilities, targeted drug delivery precision, increased payload capacity, and retained biological functionality.

    Abstract Colorectal cancer (CRC) is a significant global health concern. We need ways to detect it early and determine the best treatments. One promising method is liquid biopsy, which uses cancer cells and other components in the blood to help diagnose and treat the disease. Liquid biopsies focus on three key elements: circulating tumor DNA (ctDNA), circulating microRNA (miRNA), and circulating tumor cells (CTC). By analyzing these elements, we can identify CRC in its early stages, predict how well a treatment will work, and even spot signs of cancer returning. This study investigates the world of liquid biopsy, a rapidly growing field. We want to understand how it can help us better recognize the molecular aspects of cancer, improve and diagnostics, tailor treatments to individual patients, and keep track of the disease over the long-term. We explored specific components of liquid biopsy, like extracellular vesicles and cell-free DNA, and how they are used to detect CRC. This review sheds light on the current state of knowledge and the many ways a liquid biopsy can be used in treating colorectal cancer. It can transform patient care, disease management, and clinical outcomes by offering non-invasive cancer-targeting solutions.

    Abstract Cancer is a global health issue that requires modern treatments. Biocompatibility, variable size, and customisable targeting ligands make polymeric nanoparticles (PNPs) a flexible cancer therapy platform. Dynamic nanocarriers, Hyaluronic Acid (HA) coated PNPs, target the overexpressed CD44 receptor in cancer. Through improved permeability and retention, HA, a naturally occurring, biodegradable polymer, increases tumor accumulation and penetration. Hyaluronic acid-grafted polymeric nanoparticles (HA-PNPs) provide a number of advantages over other varieties due to their distinct characteristics. They used CD44 receptor upregulation on cancer cells for selective administration, leveraging the EPR effect for cancer site accumulation. Their natural composition improves biocompatibility while promoting conjugation with a variety of medicinal compounds and providing influence over size and surface features. HA-PNPs facilitate effective cellular uptake, safeguard their cargo, and have the possibility for regulated release, which leads to better delivery of drugs and therapeutic efficacy. While problems, such as CD44 expression variability and drug loading modification, persist, HA-PNPs offer a viable path for targeted and successful treatment of cancer due to their intrinsic benefits. HA-PNPs can be coupled with imaging agents to enable real-time tracking of the delivery of drugs and therapy response, hence enhancing individualized treatment regimens. HA-PNPs can be programmed to respond to particular environmental signals found in the tumor's microenvironment (such as pH, redox potential, and enzymes). This enables for controlled dispensing of therapeutic cargo only when it reaches the target site, reducing systemic exposure and associated negative effects. HA-PNPs have the ability to overcome common MDR processes used by cancer cells, thereby enhancing the efficiency of previously ineffective chemotherapeutic medicines. Recent advances in HA-functionalized PNP fabrication and cancer applications are covered in this article. It discusses complete treatment effectiveness and HA's targeting of tumors and receptors. The study describes production, clinical trials, and problems and prospects in turning HA-coated PNP platforms into viable therapeutic nanomedicines. HA-functionalized PNPs are versatile, targeted nanotherapeutics for various tumor types and disease stages, as shown in this comprehensive study.
