Introduction

Engineered nanoparticles have become a cornerstone in the advancement of regenerative medicine and immunotherapy, providing innovative strategies for targeted therapeutic interventions [1]. The ability to design and manipulate nanoparticles with specific physicochemical properties allows for the precise delivery of therapeutic agents, such as drugs, genes, and growth factors [2], to targeted cells or tissues. This targeted approach ensures enhanced therapeutic efficacy by minimizing off-target effects and improving the bioavailability of the active agents [3]. Nanoparticles can be tailored for optimal interaction with biological systems, which significantly contributes to their role in advancing regenerative medicine by supporting tissue repair, immune system modulation, and overall disease management [4]. The engineering of nanoparticles involves a fine balance of size, surface charge, morphology, and functionalization, all of which influence their behavior within the body and impact their therapeutic potential [5].

The application of engineered nanoparticles in regenerative medicine primarily focuses on their ability to accelerate tissue regeneration and repair damaged or diseased tissues [6]. These nanoparticles can serve as delivery vehicles for growth factors, signaling molecules, or genetic materials that are crucial for stimulating cell growth [7], differentiation, and tissue reconstruction. For example, nanoparticles can carry stem cells or gene-editing tools to facilitate tissue regeneration in conditions such as heart disease, neurodegeneration, or skin wounds [8]. The controlled release of bioactive molecules, facilitated by nanoparticles, provides a localized, sustained effect, thereby enhancing the regenerative process without causing systemic toxicity [9]. This localized treatment minimizes the risk of adverse effects, providing a safe and effective approach to tissue repair [10].

Nanoparticles also play a critical role in immunotherapy, where their versatility allows them to enhance the body's immune response against diseases, particularly in cancer and autoimmune disorders [11]. By functionalizing nanoparticles with targeting ligands, it is possible to direct them specifically to immune cells or tumor sites, improving the selectivity of therapeutic interventions [12]. In cancer therapy, for instance, engineered nanoparticles can be used to deliver chemotherapeutic agents directly to tumor cells, thereby minimizing damage to surrounding healthy tissues [13]. Furthermore, nanoparticles can be designed to modulate the immune system, either by boosting the body's natural defenses or by suppressing undesirable immune responses in autoimmune diseases [14]. This capability allows for the development of personalized immunotherapy regimens that are tailored to the specific needs of individual patients, improving therapeutic outcomes and minimizing side effects [15].
