The interaction between light and individual molecules is weak due to the size of biomolecules (≤ 10 nm) being significantly smaller than the wavelength (<i>λ</i>) of light. This limitation results in a reduced optical gradient force and diminished detection sensitivity of light on biomolecules. To overcome this challenge, we propose a single-molecule trapping and sensing method that utilizes whisper-gallery mode (WGM) coupled photonic nanojets (PNJs). Our theoretical analysis demonstrates that a focused beam with a waist radius of <i>λ</i>/6 can be generated by WGM-coupled PNJs. By harnessing this sub-diffraction-limit focused beam, we create a stable nano-optical potential well for DNA molecules. The stiffness of the potential well is measured at 0.04 pN/nm/W, which is four orders of magnitude greater than that of conventional optical tweezers. Furthermore, the molecular configuration and refractive index of an individual DNA molecule can be detected by analyzing the shift in the WGM resonance peak and the intensity variation of the backscattering signal. This work provides theoretical guidance for the trapping and sensing of single molecules in the fields of chemistry, biology, and materials science. </p></div>","PeriodicalId":51136,"journal":{"name":"Nanoscale Research Letters","volume":"20 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s11671-025-04253-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The neutralization of SARS-CoV-2 is paramount in controlling the spread and impact of COVID-19. In this context, the integration of aptamers and aptamer-related nanotherapeutics presents a valuable and scientifically significant approach. Despite the potential, current reviews in this area are often not comprehensive and specific enough to encapsulate the full scope of therapeutic principles, strategies, advancements, and challenges. This review aims to fill that gap by providing an in-depth examination of the role of aptamers and their related molecular medicine in COVID-19 therapeutics. We first introduce the unique properties, selection, and recognition mechanism of aptamers to bind with high affinity to various targets. Next, we delve into the therapeutic potential of aptamers, focusing on their ability to inhibit viral entry and replication, as well as modulate the host immune response. The integration of aptamers with nucleic acid nanomedicine is explored. Finally, we address the challenges and future perspectives of aptamer and nucleic acid nanomedicine in COVID-19 therapeutics, including issues of stability, delivery, and manufacturing scalability. We conclude by underscoring the importance of continued research and development in this field to meet the ongoing challenges posed by COVID-19 and potential future pandemics.

Doxorubin (DOX) was loaded onto the skAu, and the average size of the DOX-loaded AuNPs (c-skAuD) was measured to be 14.6 ± 0.5 nm by high-resolution transmission electron microscopy. Reaction parameters such as reaction time and DOX concentration were optimized for preparing c-skAuD. DOX was successfully loaded, as confirmed by the FT-IR results. In addition, FT-IR characterization revealed that chondroitin sulfate and collagen in the extract were involved in the synthesis of skAu. Although c-skAuD is cytotoxic to four different types of cancer cells (AGS, HeLa, A549 and MDA-MB-231), their cytotoxic effects were greatest on MDA-MB-231 cells. Analyzing cytotoxicity onto MDA-MB-231 cells revealed that c-skAuD had the greatest cytotoxicity, followed by a positive control (c-citAuD) and DOX. Furthermore, this cytotoxicity was dependent on the incubation time and DOX concentration. Cellular uptake of Au by inductively coupled plasma‒mass spectrometry demonstrated that compared with AGS cells (15.1%), MDA-MB-231 cells showed approximately two-fold greater Au uptake (29.9%) of c-skAuD. However, the Au uptake of the positive control (c-citAuD) did not significantly differ between the MDA-MB-231 and AGS cells.
