However, due to the intricate matrix composition of biological samples, there remains a need for further enhancement of sensitivity and specificity in current liquid biopsy methods to adequately meet clinical requirements. Rolling circle amplification (RCA) is an efficient isothermal enzymatic reaction capable of rapidly producing numerous ultra-long single-stranded DNA molecules with repetitive sequences. By custom-designing the DNA template sequence, RCA can generate functional products that integrate with various functional groups, achieving signal amplification and output with exceptional specificity and sensitivity in liquid biopsy. In this review, the fundamental principles and classifications of RCA are first introduced. Then, the coupling strategies of RCA with various detection technologies are systematically summarized, along with their prospects and challenges of clinical applications that have not been addressed in previous reviews, and the recent developments of RCA-based biosensors in liquid biopsy are explored.

With disturbed electrical conduction and oxidative stress in infarcted myocardium, injured heart experiences a negative ventricle remodeling process, and finally leads to heart failure. Nitric oxide (NO) is a short-lived signaling molecule regulating cardiovascular homeostasis, while vasodilation of systemic vasculature is accompanied by its exogenous supplementation. Meanwhile, connexin 43 (Cx43), a gap junction protein for electrical propagation in myocardium, is downregulated by NO derived from inducible nitric oxide synthase (iNOS). The seesaw-like relationship of Cx43 and NO in cardiac repair raises an intractable issue of how to address localized-specific NO administration and simultaneously reconstruct electrical conduction. Given that both iNOS accumulation and NO metabolism affected by oxidative stress occur in mitochondria, mitochondria-specific l-arginine (l-Arg) delivery systems are developed and are encapsulated in conductive microneedle patches. When implanted onto myocardium, l-Arg is catalyzed by iNOS to synthesize NO in mitochondria, which contributes to sustained NO administration and alleviates oxidative stress. Functional patch with equivalent conductivity to myocardium repairs electrophysiological properties of heart and upregulates Cx43 expression.
