“…Table 3 lists the surface tension of typical liquids. Water droplet, [142][143][144][145] ferrofluid, [128][129][130][131] oil droplet, [141] and liquid metal robots [132][133][134][135][136][137][138][139][140] are some examples of soft liquid robots. These robots are substantially softer and more compliant than other soft materials, making them extremely deformable with a higher degree of freedom while navigating through constrained spaces.…”

Small‐scale robots (SSRs) have emerged as promising and versatile tools in various biomedical, sensing, decontamination, and manipulation applications, as they are uniquely capable of performing tasks at small length scales. With the miniaturization of robots from the macroscale to millimeter‐, micrometer‐, and nanometer‐scales, the viscous and surface forces, namely adhesive forces and surface tension have become dominant. These forces significantly impact motion efficiency. Surface engineering of robots with both hydrophilic and hydrophobic functionalization presents a brand‐new pathway to overcome motion resistance and enhance the ability to target and regulate robots for various tasks. This review focuses on the current progress and future perspectives of SSRs with hydrophilic and hydrophobic modifications (including both tethered and untethered robots). The study emphasizes the distinct advantages of SSRs, such as improved maneuverability and reduced drag forces, and outlines their potential applications. With continued innovation, rational surface engineering is expected to endow SSRs with exceptional mobility and functionality, which can broaden their applications, enhance their penetration depth, reduce surface fouling, and inhibit bacterial adhesion.

“…In the last step, the CFs pretreated by thermal oxidation and 0.1 M C 6 H 8 O 6 as a reducing agent were added to enable the 3D flower-like Ag to grow spontaneously and anisotropically. The color of the solution immediately changed into dark brown, and the reaction lasted different times (5,15,25) The encapsulation process of composite 3D flower-like Ag-CF electrodes is provided in Section S1 in the Supporting Information.…”

“…Nevertheless, it is difficult to apply the direct geological observation method commonly used on land because of the obstruction of seawater when detecting the deep seabed . Hence, a great deal of research efforts had been dedicated to the development of submarine oil exploration. , Among various marine electric field sensors, capacitive composite electrodes (CCEs) − have attracted tremendous scientific interest thanks to their impressive properties of fast response, safe operation, low cost, and long service lifetime. However, compared to electrochemical composite electrodes (ECEs), − the pristine potential difference stability of CCEs is relatively poor, which limits their usage in practical applications.…”

Construction of three-dimensional (3D) flower-like nanostructures with controlled morphologies has emerged as an attractive tool by scientists in the marine electric field sensor research field due to their peculiar structural features. Herein, novel 3D flower-like Ag-CF capacitive composite electrodes have been created by an eco-friendly water-bath strategy via AgNO3 as a sliver source and subsequently compounded with carbon fibers (CFs) pretreated by thermal oxidation. A series of electrode samples with various morphologies obtained by modulating different reaction times and temperatures bring about the dominant formation mechanism of these nanostructures and the influence behavior on the CF electrode in detail. Especially, the 3D flower-like Ag-CF electrode shows a large surface area acquired under the conditions of 80 °C and 15 min, which can provide more electroactive sites in electrochemical analysis and exhibit a maximum areal specific capacitance of 619.75 mF·cm–2 at a scanning speed of 10 mV·s–1. This is mainly due to the synergistic behavior of the unique 3D flower-like morphology and the large specific surface area of CFs. Furthermore, a cylinder-shaped Ag-CF sensor is designed, which delivers a superior potential difference of 33.08 μV, a potential difference drift of 18.62 μV/24 h for 30 days, and a self-noise of 0.92 nV/rt (Hz)@1 Hz. In this work, the intriguing synthesis strategy can be a promising facile approach to manufacture the controllable 3D flower-like Ag-CF electrode for electric field sensor applications.

“…In 2006, Inglese et al came up with a quantitative HTS (qHTS) strategy in order to enhance screening precision and accuracy; in a manner, the assays are conducted with numerous compounds’ concentrations in a magnitude ranging at more than four orders to create dose–response curves, which are in all of the tested compounds ( 71 ). This method of qHTS has led to an increase in the accuracy of screening compared with the old traditional HTS, since there is no longer a need for the primary single-concentration screening step that was known for its possibility of producing a high rate of false negatives and false positives ( 72 ).…”

Cancer is a devastating disease that takes the lives of millions of people globally every year. Precision cancer therapy is based on a patient’s tumor histopathology, expression analyses, and/or tumor RNA or DNA analysis. Only 2%–20% of patients with solid tumors benefit from genomics-based precision oncology. Therefore, functional diagnostics and patient-derived cancer models are needed for precision cancer therapy. In this review, we will summarize the potential use of conditional cell reprogramming (CR) and robotic high-throughput screening in precision cancer medicine. Briefly, the CR method includes the co-culturing of irradiated Swiss-3T3-J2 mouse fibroblast cells alongside digested primary non-pathogenic or pathogenic cells with the existence of Rho-associated serine–threonine protein kinase inhibitor called Y-27632, creating an exterior culture environment, allowing the cells to have the ability to gain partial properties of stem cells. On the other hand, quantitative high-throughput screening (qHTS) assays screen thousands of compounds that use cells in a short period of time. The combination of both technologies has the potential to become a driving force for precision cancer therapy.
