Cancer has become the leading cause of death in recent years. As great advances in medical treatment, emerging therapies of various cancers have been developed. Current treatments include surgery, radiotherapy, chemotherapy, immunotherapy, and targeted therapy. Aptamers are synthetic ssDNA or RNA. They can bind tightly to target molecules due to their unique tertiary structure. It is easy for aptamers to be screened, synthesized, programmed, and chemically modified. Aptamers are emerging targeted drugs that hold great potentials, called therapeutic aptamers. There are few types of therapeutic aptamers that have already been approved by the US Food and Drug Administration (FDA) for disease treatment. Now more and more therapeutic aptamers are in the stage of preclinical research or clinical trials. This review summarized the screening and development of therapeutic aptamers against different types of cancer cells.

Targeted drug delivery significantly enhances therapeutic efficacy across various diseases, particularly in cancer treatments, where conventional approaches such as chemotherapy and radiotherapy often cause severe side effects. In this context, nucleic acid aptamers-short, single-stranded DNA or RNA oligonucleotides capable of binding specific targets with high affinity-have emerged as promising tools for precision drug delivery and therapy. Aptamers can be selected against whole, living cells using SELEX and chemically modified for diverse applications.

Breast cancer (BC), characterized by its heterogeneity and diverse subtypes, necessitates personalized treatment strategies. This study presents MF3Ec-TBPP nanoparticles (NPs) as a promising approach, integrating an aggregation-induced emission (AIE)-based photosensitizer, TBPP, with the MF3Ec aptamer to enhance targeted photodynamic therapy (PDT) for Luminal A subtype BC cells. The nanoparticles also feature a 1, 2-distearoyl-sn-glycero-3-phosphoethanolamine-poly(ethylene glycol) shell and dipalmitoyl phosphatidylcholine (DPPC), which stabilize the structure and inhibit singlet oxygen generation, effectively reducing off-target effects and protecting healthy tissues.

Musculoskeletal disorders, including bone fractures, osteoarthritis, and muscle injuries, represent a leading cause of global disability, revealing the urgency for advanced therapeutic solutions. However, current therapies face limitations including donor-site morbidity, immune rejection, and inadequate mimicry of dynamic tissue repair processes. DNA-based hydrogels emerge as transformative platforms for musculoskeletal reconstruction, with their sequence programmability, dynamic adaptability, and biocompatibility to balance structural support and biological functions.

Neurodegenerative diseases (NDs), including Alzheimer's, Huntington's, and Parkinson's disease, are associated with significant declines in cognitive function and mobility. The accumulation of misfolded proteins such as β-amyloid, tau, α-synuclein, and polyglutamates is a key factor in the progression of these conditions. Unfortunately, traditional small-molecule drugs face major obstacles in effectively targeting these proteins.

However, this approach infers rather than quantify aptamer specificity. Here we present a novel strategy for directly quantifying aptamer specificity within enriched libraries termed Aptamer Specificity Sequencing for Efficient Targeting (ASSET).
